- Method Detail
  - send
```
void send(org.apache.iotdb.tsfile.read.common.block.TsBlock tsBlock)
```
    Sends a tsBlock to an unpartitioned buffer. If no-more-tsBlocks has been set, the send tsBlock call is ignored. This can happen with limit queries.
  - setNoMoreTsBlocks
```
void setNoMoreTsBlocks()
```
    Notify SinkHandle that no more tsBlocks will be sent. Any future calls to send a tsBlock are ignored.
  - abort
```
void abort()
```
    Abort the sink handle, discarding all tsBlocks which may still in memory buffer, but blocking readers. It is expected that readers will be unblocked when the failed query is cleaned up.
