类型参数:

R - request message type

P - response message type

M - message parameters type

所有超级接口:

RestHandlerSpecification, UntypedResponseMessageHeaders<R,M>

所有已知实现类:

AbstractAggregatedMetricsHeaders, AbstractMetricsHeaders, AggregatedJobMetricsHeaders, AggregatedSubtaskMetricsHeaders, AggregatedTaskManagerMetricsHeaders, AsynchronousOperationStatusMessageHeaders, AsynchronousOperationTriggerMessageHeaders, CheckpointConfigHeaders, CheckpointingStatisticsHeaders, CheckpointStatisticDetailsHeaders, ClusterConfigurationInfoHeaders, ClusterOverviewHeaders, DashboardConfigurationHeaders, JobAccumulatorsHeaders, JobCancellationHeaders, JobConfigHeaders, JobDetailsHeaders, JobExceptionsHeaders, JobExecutionResultHeaders, JobIdsWithStatusesOverviewHeaders, JobManagerMetricsHeaders, JobMetricsHeaders, JobPlanHeaders, JobsOverviewHeaders, JobSubmitHeaders, JobVertexAccumulatorsHeaders, JobVertexBackPressureHeaders, JobVertexDetailsHeaders, JobVertexMetricsHeaders, JobVertexTaskManagersHeaders, JobVertexWatermarksHeaders, RescalingStatusHeaders, RescalingTriggerHeaders, SavepointDisposalStatusHeaders, SavepointDisposalTriggerHeaders, SavepointStatusHeaders, SavepointTriggerHeaders, ShutdownHeaders, StopWithSavepointTriggerHeaders, SubtaskCurrentAttemptDetailsHeaders, SubtaskExecutionAttemptAccumulatorsHeaders, SubtaskExecutionAttemptDetailsHeaders, SubtaskMetricsHeaders, SubtasksAllAccumulatorsHeaders, SubtasksTimesHeaders, TaskCheckpointStatisticsHeaders, TaskManagerDetailsHeaders, TaskManagerMetricsHeaders, TaskManagersHeaders

public interface MessageHeaders<R extends RequestBody,P extends ResponseBody,M extends MessageParameters>
extends UntypedResponseMessageHeaders<R,M>

This class links RequestBodys to ResponseBodys types and contains meta-data required for their http headers.

Implementations must be state-less.
