disruptor-proxy

Byte-code generator to create Disruptor-backed proxies

Example

final RingBufferProxyGeneratorFactory generatorFactory = new RingBufferProxyGeneratorFactory();

final T tImpl = new ConcreteT();

final RingBufferProxyGenerator generator = generatorFactory.create(GeneratorType.BYTECODE_GENERATION);

final T proxy = generator.createRingBufferProxy(tImpl, T.class, disruptor);

disruptor.start();

GeneratorType

• GeneratorType.JDK_REFLECTION - uses java.lang.reflect.Proxy to generate a dynamic proxy that will add events to the RingBuffer. Use this for minimal dependencies.
• GeneratorType.BYTECODE_GENERATION - uses Javassist to generate classes that will add events to the RingBuffer. Use this for maximum performance.

Performance

Tests performed on Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz

[JDK_REFLECTION] - Ops per second: 14461091.00, avg latency 69ns

[BYTECODE_GENERATION] - Ops per second: 18313904.00, avg latency 54ns

Issues

Currently creates wrapper objects (java.lang) for any primitive method arguments, so generates unnecessary garbage.

Dependencies

Minimal dependency is the Disruptor JAR.

If you are using byte-code generation for the proxy class (specified by GeneratorType), you'll also need the Javassist JAR. Both are included in the download.
