+= 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 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]
+2) measure time in ns from first request to receiving last reply over set amount of requests
