        public org.apache.iotdb.tsfile.read.common.block.TsBlock receive()
        Description copied from interface: ISourceHandle
        Get a TsBlock. If the source handle is blocked, a null will be returned. A RuntimeException will be thrown if any error happened.
        Specified by:
        receive in interface ISourceHandle

      • isBlocked

        public com.google.common.util.concurrent.ListenableFuture<?> isBlocked()
        Description copied from interface: ISourceHandle
        Get a future that will be completed when the input buffer is not empty.

        isBlocked in interface ISourceHandle

      • abort

        public void abort()
        Description copied from interface: ISourceHandle
        Abort the handle. Discard all tsblocks which may still be in the memory buffer and cancel the future returned by ISourceHandle.isBlocked().

        Should only be called in abnormal case
