Method Detail

open

public void open(DataSpec dataSpec)
          throws java.io.IOException

Description copied from interface: DataSink

Opens the sink to consume the specified data.

Note: If an IOException is thrown, callers must still call DataSink.close() to ensure that any partial effects of the invocation are cleaned up.

Specified by:

open in interface DataSink

Parameters:

dataSpec - Defines the data to be consumed.

Throws:

java.io.IOException - If an error occurs opening the sink.

close

public void close()
           throws java.io.IOException

Description copied from interface: DataSink

Closes the sink.

Note: This method must be called even if the corresponding call to DataSink.open(DataSpec) threw an IOException. See DataSink.open(DataSpec) for more details.

Specified by:

close in interface DataSink

Throws:

java.io.IOException - If an error occurs closing the sink.

write

public void write(byte[] buffer,
                  int offset,
                  int length)
           throws java.io.IOException

Description copied from interface: DataSink

Consumes the provided data.

Specified by:

write in interface DataSink

Parameters:

buffer - The buffer from which data should be consumed.

offset - The offset of the data to consume in buffer.

length - The length of the data to consume, in bytes.

Throws:

java.io.IOException - If an error occurs writing to the sink.

getData

public byte[] getData()

Returns the data written to the sink since the last call to open(DataSpec), or null if open(DataSpec) has never been called.
