for Row
consumption.Modifier and Type | Method and Description |
---|---|
com.datastax.oss.driver.api.core.cql.ColumnDefinitions |
columnDefinitions()
Get the
ColumnDefinitions provided by the backing ResultSet for this stream. |
CassandraRowStream |
endHandler(Handler<Void> handler)
Set an end handler.
|
CassandraRowStream |
exceptionHandler(Handler<Throwable> handler)
Set an exception handler on the read stream.
|
com.datastax.oss.driver.api.core.cql.ExecutionInfo |
executionInfo()

ExectionInfo provided by the backing ResultSet for this stream. |
CassandraRowStream |
fetch(long l)
Fetch the specified
amount of elements. |
CassandraRowStream |
handler(Handler<com.datastax.oss.driver.api.core.cql.Row> handler)
Set a data handler.
|
CassandraRowStream |
pause()
Pause the
ReadStream , it sets the buffer in fetch mode and clears the actual demand. |
default Future<Void> |
pipeTo(WriteStream<com.datastax.oss.driver.api.core.cql.Row> dst)
Same as
ReadStream.pipeTo(WriteStream, Handler) but returns a Future of the asynchronous result |
default void |
pipeTo(WriteStream<com.datastax.oss.driver.api.core.cql.Row> dst,
Handler<AsyncResult<Void>> handler)
Pipe this
ReadStream to the WriteStream . |
CassandraRowStream |

ReadStream
ReadStream
, it sets the buffer in fetch

While it's paused, no data will be sent to the data handler
.

ReadStream
ReadStream
to the WriteStream
.
Elements emitted by this stream will be written to the write stream until this stream ends or fails.
Once this stream has ended or failed, the write stream will be ended and the handler
will be
called with the result.
