Class TaskManagerServices

java.lang.Object

org.apache.flink.runtime.taskexecutor.TaskManagerServices

public class TaskManagerServices
extends Object

Container for TaskExecutor services such as the MemoryManager, IOManager, ShuffleEnvironment. All services are exclusive to a single TaskExecutor. Consequently, the respective TaskExecutor is responsible for closing them.
