Examples of com.hazelcast.core.IExecutorService

com.hazelcast.core.IExecutorService
Distributed implementation of {@link ExecutorService}. IExecutorService provides additional methods like executing tasks on a specific member, on a member who is owner of a specific key, executing a tasks on multiple members and listening execution result using a callback. @see ExecutorService @see ExecutionCallback @see MultiExecutionCallback
