Interface OperationService

public interface OperationService

The OperationService is responsible for executing operations. A single operation can be executed locally using runOperation(Operation) and executeOperation(Operation). Or it can executed remotely using the one of the send methods. It also is possible to execute multiple operation one multiple partitions using one of the invoke methods.
