-This package contains basic examples for jvpp. To run the examples:
-
-- 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
-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]

-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
