接口摘要

WorkerComputable<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	Worker computation interface for an application.
WorkerInterceptor<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	WorkerInterceptor is a entry point for all services in worker implementation.

类摘要

AbstractWorkerComputable<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable,KEY extends Bytable,VALUE extends Bytable>	Abstract implementation to load data one by one.
AbstractWorkerCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	AbstractWorkerCoordinator has some common implementation for both async and sync worker coordinator.
AsyncWorkerCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	AsyncWorkerCoordinator is used to as a worker barrier for each iteration.
BasicWorkerInterceptor<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	Empty WorkerInterceptor implementation for user to choose which function should be override.
GuaguaWorkerService<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	GuaguaWorkerService is the basic implementation as a worker for whole application process.
InternalWorkerCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	InternalWorkerCoordinator is local coordinator implementation on one jvm instance.
MemoryStatsWorkerInterceptor<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	MemoryStatsWorkerInterceptor is used to print memory usage for each worker checkpoint.
SyncWorkerCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	SyncWorkerCoordinator is used to as a worker barrier for each iteration.
TraceWorkerInterceptor<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	TraceWorkerInterceptor is used to trace whole application process.
WorkerComputableTimer<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	WorkerComputableTimer is used to get execution time for computation.
WorkerContext<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	WorkerContext is a context to contain all objects used in master computation.
WorkerTimer<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	WorkerTimer is used to get execution time of the post intercepters and computation.
