+= JVpp
+
+JVpp is JNI based Java API for VPP.
+
+== Features
+It is:
+
+* Asynchronous
+* Fully generated
+* Lightweight
+
+== Architecture
+
+=== Plugin support
+
+ /-------------\ /--------------\ /---------------\
+ | JvppPlugin1 +<-------+ JVppRegistry +--------->+ VppConnection |
+ \-------------/ inits \--+-----------/ uses \---------------/
+ |
+ /-------------\ |
+ | JvppPlugin2 +<----------+ inits
+ \-------------/ |
+ |
+ ... |
+ |
+ /----------\ |
+ | JVppCore +<-------------+
+ \----------/
+
+
+VppRegistry opens connection to vpp (VppConnection) and manages jvpp plugins.
+Each plugin needs to be registered in the VppRegistry. Registration involves
+plugin initialization (providing JNI implementation with JVppCallback reference,
+vpp client identifier and vpp shared memory queue address).
+
+API user sends message by calling a method of appropriate plugin interface.
+The call is delegated to JNI implementation provided by the particular plugin.
+When JNI code receives reply, it invokes callback method of JVppCallback
+that corresponds to the received message reply.
+
+=== JVppCore as an example of JVpp plugin architecture
+
+ JVpp Java
+
+ /--------------\ /----------\ /------------\ /------\
+ | JVppRegistry | | JVppCore | | Callbacks | | DTOs |
+ \----+---------/ \----+-----/ \------+-----/ \------/
+ ^ ^ ^
+ | implements | implements | implements
+ /----+--------------\ /---+----------\ /-----+---------\
+ | JVppRegistryImpl* +-------->+ JVppCoreImpl | | JVppCallback |
+ \-------+-----------/ inits \---+----------/ \-------+-------/
+ | | ^
+ | | uses | calls back
+ | | |
+----------|--------------------------|-----------------------|---------------------
+ | | |
+ C JNI | +-------------------+ | /-----------------\
+ v | | +-->+ jvpp_core_gen.h |
+ /--------+--------\ | | | \-----------------/
+ | jpp_registry.c* +---+ /--------+----+----\ | | |
+ \-----------------/ | | << shared lib >> | /-+--+---+------\
+ + ->+ jvpp_common* <--------+ jvpp_core.c* |
+ uses \------------------/ uses \---------------/
+
+
+* Components marked with an asterisk contain manually crafted code, which in addition
+to generated classes form jvpp. Exception applies to Callbacks and DTOs, since there are
+manually crafted marker interfaces in callback and dto package (dto/JVppRequest, dto/JVppReply,
+dto/JVppDump, dto/JVppReplyDump, callback/JVppCallback)
+
+Note: jvpp_core.c calls back the JVppCallback instance with every response. An instance of the
+JVppCallback is provided to jvpp_core.c by JVppRegistryImpl on JVppCoreImpl initialization.
+
+Part of the JVpp is also Future facade. It is asynchronous API returning Future objects
+on top of low level JVpp. It wraps dump reply messages in one DTO using control_ping message
+(provided by JVppRegistry).
+
+
+Future facade
+
+ /----------------\ /---------------\
+ | FutureJVppCore | +-->+ JVppRegistry* |
+ \-----+----------/ | \---------------/
+ ^ |
+ | implements | uses
+ | |
+ /--------+-------------\ | /------------------------------\
+ | FutureJVppCoreFacade +---+--->+ FutureJVppCoreFacadeCallback |
+ \---------+------------/ uses \-------+----------------------/
+ | |
+---------------|-----------------------------|-------------------------------
+ | uses | implements
+JVpp Java | |
+ | |
+ /----------\ | |
+ | JVppCore +<-+ |
+ \----+-----/ |
+ ^ |
+ | implements v
+ /----+---------\ /--------+---------------\
+ | JVppCoreImpl | | JVppCoreGlobalCallback |
+ \--------------/ \------------------------/
+
+
+
+Another useful utility of the JVpp is Callback facade. It is asynchronous API
+capable of calling specific callback instance (provided when performing a call)
+per call.
+
+
+Callback facade
+
+ /------------------\ /---------------\
+ | CallbackJVppCore | +-->+ JVppRegistry* |

+ ^ |
+ | implements | uses
+ | |
+ /--------+---------------\ | /--------------------------\
+ | CallbackJVppCoreFacade +---+--->+ CallbackJVppCoreCallback |
+ \---------+--------------/ uses \-----+--------------------/
+ | |
+---------------|-----------------------------|-------------------------------
+ | uses | implements
+JVpp Java | |
+ | |
+ /----------\ | |
+ | JVppCore +<-+ |
+ \----+-----/ |
+ ^ |
+ | implements v
+ /----+---------\ /----------+-------------\
+ | JVppCoreImpl | | JVppCoreGlobalCallback |
+ \--------------/ \------------------------/
+
+
+== Package structure
+
+* *io.fd.vpp.jvpp* - top level package for generated JVpp interface+ implementation and hand-crafted
+VppConnection interface + implementation - packaged as jvpp-registry-version.jar
+
+* *io.fd.vpp.jvpp.[plugin]* - top level package for generated JVpp interface + implementation
++ plugin's API tests - packaged as jvpp-[plugin]-version.jar
+
+** *dto* - package for DTOs generated from VPP API structures + base/marker hand-crafted interfaces
+(in case of jvpp-registry)
+** *callback* - package for low-level JVpp callbacks and a global callback interface implementing each of
+the low-level JVppcallbacks
+** *future* - package for future based facade on top of JVpp and callbacks
+** *callfacade* - package for callback based facade on top of JVpp and callbacks. Allowing
+users to provide callback per request
+** *test* - package for JVpp standalone tests. Can also serve as samples for JVpp.
+
+C code is structured into modules:
+
+* *jvpp_common* - shared library that provides jvpp_main_t reference used by jvpp_registry and plugins.
+
+* *jvpp_registry* - native library used by JVppRegistryImpl, responsible for:
+
+** VPP connection open/close
+** Rx thread to java thread attach
+** control ping message handling
+
+* *jvpp_core* - native library used by jvpp core plugin:
+** *jvpp_core.c* - contains hand crafted code for core plugin initialization
+** *jvpp_core_gen.h* - contains generated JNI compatible handlers for all requests and replies defined in vpe.api
+
+== Code generators
+All of the required code except the base/marker interfaces is generated using
+simple python2 code generators. The generators use __defs_vpp_papi.py__ input
+file produced by __vppapigen__ from vpe.api file.
+
+=== JNI compatible C code
+Produces __jvpp_[plugin]_gen.h__ file containing JNI compatible handlers for each VPP
+request and reply.
+
+[NOTE]
+====
+Source: jvpp_c_gen.py
+====
+
+=== Request/Reply DTOs
+For all the structures in __defs_vpp_papi.py__ a POJO DTO is produced. Logically,
+there are 4 types of DTOs:
+
+* Request - requests that can be sent to VPP and only a single response is expected
+* DumpRequest - requests that can be sent to VPP and a stream of responses is expected
+* Reply - reply to a simple request or a single response from dump triggered response stream
+* ReplyDump - collection of replies from a single dump request
+* Notifications/Events - Not implemented yet
+
+[NOTE]
+====
+Source: dto_gen.py
+====
+
+=== JVpp
+Produces __JVpp.java__ and __JVppImpl.java__. This is the layer right above JNI compatible C
+code.
+
+[NOTE]
+====
+Source: jvpp_impl_gen.py
+====
+
+=== Callbacks
+Produces callback interface for each VPP reply + a global callback interface called
+__JVpp[plugin]GlobalCallback.java__ aggregating all of the callback interfaces. The JNI
+compatible C code expects only a single instance of this global callback and calls
+it with every reply.
+
+[NOTE]
+====
+Source: callback_gen.py
+====
+
+=== Future facade
+Produces an asynchronous facade on top of JVpp and callbacks, which returns a Future that provides
+matching reply once VPP invocation finishes. Sources produced:
+__FutureJVpp[plugin].java, FutureJVpp[plugin]Facade.java and FutureJVpp[plugin]Callback.java__
+
+[NOTE]
+====
+Source: jvpp_future_facade_gen.py
+====
+
+=== Callback facade
+Similar to future facade, only this facade takes callback objects as part of the invocation
+and the callback is called with result once VPP invocation finishes. Sources produced:
+__CallbackJVpp[plugin].java, CallbackJVpp[plugin]Facade.java and CallbackJVpp[plugin]Callback.java__
+
+[NOTE]
+====
+Source: jvpp_callback_facade_gen.py

+This is the experimental version of Lua API, aimed for the luajit use.
+
+Please take a look and send the feedback to ayourtch@gmail.com.
+
+To run the examples here:
+
+1) install luajit - "sudo apt-get install luajit" on ubuntu
+
+2) "make build-vpp-api" in the top VPP directory
+
+3) "make run" in a separate terminal window
+ This ensures you have an instance of VPP running
+
+4) sudo luajit examples/example-cli.lua
+
+This will result in something like this:
+
+Version:
+00000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................

+,["retval"] = 0,["context"] = 0,} ,}
+---
+
+5) You can also run the performance test bench:
+
+$ sudo luajit bench.lua
+10001 iterations, average speed 5624LL per second
+10001 iterations, average speed 6650LL per second
+10001 iterations, average speed 6053LL per second
+10001 iterations, average speed 7056LL per second
+10001 iterations, average speed 6388LL per second
+10001 iterations, average speed 5849LL per second
+10001 iterations, average speed 6321LL per second
+10001 iterations, average speed 6368LL per second
+10001 iterations, average speed 5958LL per second
+10001 iterations, average speed 6482LL per second
+Average tps across the tests: 6274LL
+
+Note: the above is run in an lxd container running inside 2-core
+xhyve VM on a Macbook Pro, so I would not take the performance numbers for granted :)
+
+The "examples" directory contains a few naive examples, as well as a couple of more
+advanced ones - a tab-completing CLI for VPP that can call both the APIs and CLI,
+and also a small test utility which I use for automating some small tests using
+VPP.

+This is a small helper utility to automate some simple tests
+that one might need to do.
+
+Think of it as a hybrid of a screen and expect who
+also took some habits from HTML inline code.
+
+It is quite probably useless for building anything serious,
+but practice shows it is quite efficient at allowing
+convenient temporary quick tests, and for something
+that was written over a course of a couple of evenings it
+is quite a nice little helper tool.
+
+It allows do launch and drive multiple shell sessions,
+and by virtue of having been written in Lua, it of course
+also allows to add the business logic using the Lua code.
+
+If you launch the lute without parameters, it gives you
+the interactive shell to execute the commands in.
+
+If you launch it with an argument, it will attempt to
+read and execute the commands from the file.
+
+Commands:
+
+shell FOO
+
+ spawn a shell in a new PTY under the label FOO.
+
+run FOO bar
+
+ Send "bar" keystrokes followed by "ENTER" to the session FOO
+
+ Special case: "break" word on its own gets translated into ^C being sent.
+
+cd FOO
+
+ "change domain" into session FOO. All subsequent inputs will go,
+ line-buffered, into the session FOO. To jump back up, use ^D (Control-D),
+ or within the file, use ^D^D^D (caret D caret D caret D on its own line)
+
+expect FOO blablabla
+
+ Pause further interpretation of the batch mode until you see "blablabla"
+ in the output of session FOO, or until timeout happens.
+
+sleep N
+
+ Sleep an integer N seconds, if you are in batch mode.
+
+echo blabla
+
+ Echo the remainder of the line to standard output.
+
+For Lua code, there is a pre-existing pseudo-session called "lua",
+which accepts "run lua" command which does what you would expect
+(evaluate the rest of the string in Lua context - being the same
+as lute itself). Also you can do "cd lua" and get into a
+multiline-enabled interpreter shell.
+
+This way for the VPP case you can automate some of the things in your routine
+that you would have to have done manually, and test drive API as well
+as use the realistic native OS components to create the environment around it.

+# VPP API module {#vapi_doc}
+
+## Overview
+
+VPP API module allows communicating with VPP over shared memory interface.
+The API consists of 3 parts:
+
+* common code - low-level API
+* generated code - high-level API
+* code generator - to generate your own high-level API e.g. for custom plugins
+
+### Common code
+
+#### C common code
+
+C common code represents the basic, low-level API, providing functions to
+connect/disconnect, perform message discovery and send/receive messages.
+The C variant is in vapi.h.
+
+#### C++ common code
+
+C++ is provided by vapi.hpp and contains high-level API templates,
+which are specialized by generated code.
+
+### Generated code
+
+Each API file present in the source tree is automatically translated to JSON
+file, which the code generator parses and generates either C (`vapi_c_gen.py`)
+or C++ (`vapi_cpp_gen.py`) code.
+
+This can then be included in the client application and provides convenient way
+to interact with VPP. This includes:
+
+* automatic byte-swapping
+* automatic request-response matching based on context
+* automatic casts to appropriate types (type-safety) when calling callbacks
+* automatic sending of control-pings for dump messages
+
+The API supports two modes of operation:
+
+* blocking
+* non-blocking
+
+In blocking mode, whenever an operation is initiated, the code waits until it
+can finish. This means that when sending a message, the call blocks until
+the message can be written to shared memory. Similarly, receiving a message
+blocks until a message becomes available. On higher level, this also means that
+when doing a request (e.g. `show_version`), the call blocks until a response
+comes back (e.g. `show_version_reply`).
+
+In non-blocking mode, these are decoupled, the API returns VAPI_EAGAIN whenever
+an operation cannot be performed and after sending a request, it's up to
+the client to wait for and process a response.
+
+### Code generator
+
+Python code generator comes in two flavors - C and C++ and generates high-level
+API headers. All the code is stored in the headers.
+
+## Usage
+
+### Low-level API
+
+Refer to inline API documentation in doxygen format in `vapi.h` header
+for description of functions. It's recommened to use the safer, high-level
+API provided by specialized headers (e.g. `vpe.api.vapi.h`
+or `vpe.api.vapi.hpp`).
+
+#### C high-level API
+
+##### Callbacks
+
+The C high-level API is strictly callback-based for maximum efficiency.
+Whenever an operation is initiated a callback with a callback context is part
+of that operation. The callback is then invoked when the response (or multiple
+responses) arrive which are tied to the request. Also, callbacks are invoked
+whenever an event arrives, if such callback is registered. All the pointers
+to responses/events point to shared memory and are immediately freed after
+callback finishes so the client needs to extract/copy any data in which it
+is interested in.
+
+#### Blocking mode
+
+In simple blocking mode, the whole operation (being a simple request or a dump)
+is finished and it's callback is called (potentially multiple times for dumps)
+during function call.
+
+Example pseudo-code for a simple request in this mode:
+
+`
+vapi_show_version(message, callback, callback_context)
+
+1. generate unique internal context and assign it to message.header.context
+2. byteswap the message to network byte order
+3. send message to vpp (message is now consumed and vpp will free it)
+4. create internal "outstanding request context" which stores the callback,
+ callback context and the internal context value
+5. call dispatch, which in this mode receives and processes responses until
+ the internal "outstanding requests" queue is empty. In blocking mode, this
+ queue always contains at most one item.
+`
+
+**Note**: it's possible for different - unrelated callbacks to be called before
+the response callbacks is called in cases where e.g. events are stored
+in shared memory queue.
+
+#### Non-blocking mode
+
+In non-blocking mode, all the requests are only byte-swapped and the context
+information along with callbacks is stored locally (so in the above example,
+only steps 1-4 are executed and step 5 is skipped). Calling dispatch is up to
+the client application. This allows to alternate between sending/receiving
+messages or have a dedicated thread which calls dispatch.
+
+### C++ high level API
+
+#### Callbacks
+
+In C++ API, the response is automatically tied to the corresponding `Request`,
+`Dump` or `Event_registration` object. Optionally a callback might be specified,
+which then gets called when the response is received.
+
+**Note**: responses take up shared memory space and should be freed either
+manually (in case of result sets) or automatically (by destroying the object
+owning them) when no longer needed. Once a Request or Dump object was executed,
+it cannot be re-sent, since the request itself (stores in shared memory)
+is consumed by vpp and inaccessible (set to nullptr) anymore.
+
+#### Usage
+
+#### Requests & dumps
+
+0. Create on object of `Connection` type and call `connect()` to connect to vpp.
+1. Create an object of `Request` or `Dump` type using it's typedef (e.g.
+ `Show_version`)
+2. Use `get_request()` to obtain and manipulate the underlying request if
+ required.
+3. Issue `execute()` to send the request.
+4. Use either `wait_for_response()` or `dispatch()` to wait for the response.
+5. Use `get_response_state()` to get the state and `get_response()` to read
+ the response.
+
+#### Events
+
+0. Create a `Connection` and execute the appropriate `Request` to subscribe to
+ events (e.g. `Want_stats`)
+1. Create an `Event_registration` with a template argument being the type of
+ event you are insterested in.
+2. Call `dispatch()` or `wait_for_response()` to wait for the event. A callback
+ will be called when an event occurs (if passed to `Event_registration()`
+ constructor). Alternatively, read the result set.
+
+**Note**: events stored in the result set take up space in shared memory
+and should be freed regularly (e.g. in the callback, once the event is
+processed).
