-= JVpp
-
-JVpp is JNI based Java API for VPP.
-
-== Features
-It is:
-
-* Asynchronous
-* Fully generated
-* Lightweight
-
-== Architecture
-
-=== Plugin support
-

-  \----------/
-
-
-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

-* 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).

-== 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

-
-- Make sure VPP is running
-- From VPP's build-root/ folder execute:
-  - release version: sudo java -cp build-vpp-native/vpp/vpp-api/java/jvpp-registry-18.01.jar:build-vpp-native/vpp/vpp-api/java/jvpp-core-18.01.jar io.fd.vpp.jvpp.core.examples.[test name]

-
-Available examples:
-CallbackApiExample - Similar to ControlPingTest, invokes more complex calls (e.g. interface dump) using low level JVpp APIs
-CallbackJVppFacadeNotificationExample - Example of interface notifications using Callback based JVpp facade
-CallbackJVppFacadeExample - Execution of more complex calls using Callback based JVpp facade
-CallbackNotificationApiExample -  Example of interface notifications using low level JVpp APIs
-CreateSubInterfaceExample - Example of sub-interface creation
-FutureApiNotificationExample - Example of interface notifications using Future based JVpp facade
-FutureApiExample - Execution of more complex calls using Future based JVpp facade
-L2AclExample - Example of L2 ACL creation
-LispAdjacencyExample - Example of lisp adjacency creation and read (custom vpe.api type support showcase)
-
-CallbackApiReadPerfTest, FutureApiReadPerfTest, CallbackApiWritePerfTest - test provide two ways to count invocations:
-1) maximum number of invocations and received replyies within 1 sec

-This package contains basic tests for jvpp. To run the tests:
-
-- Make sure VPP is running
-- From VPP's build-root/ folder execute:
-  - release version: sudo java -cp build-vpp-native/vpp/vpp-api/java/jvpp-registry-17.10.jar:build-vpp-native/vpp/vpp-api/java/jvpp-core-17.10.jar io.fd.vpp.jvpp.core.test.[test name]

-
-Available tests:
-CallbackApiTest - Similar to ControlPingTest, invokes more complex calls (e.g. interface dump) using low level JVpp APIs
-CallbackJVppFacadeNotificationTest - Tests interface notifications using Callback based JVpp facade
-CallbackJVppFacadeTest - Execution of more complex calls using Callback based JVpp facade
-CallbackNotificationApiTest - Tests interface notifications using low level JVpp APIs
-ControlPingTest - Simple test executing a single control ping using low level JVpp APIs
-CreateSubInterfaceTest - Tests sub-interface creation
-FutureApiNotificationTest - Tests interface notifications using Future based JVpp facade
-FutureApiTest - Execution of more complex calls using Future based JVpp facade
-L2AclTest - Tests L2 ACL creation
-LispAdjacencyTest - Tests lisp adjacency creation and read (custom vpe.api type support showcase)
