Modifier and Type	Method and Description
void	close() Closes the sink.
void	open(DataSpec dataSpec) Opens the sink to consume the specified data.
void	write(byte[] buffer, int offset, int length) Consumes the provided data.

Method Detail

open

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

Opens the sink to consume the specified data.

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

Parameters:

dataSpec - Defines the data to be consumed.

Throws:

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

write

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

Consumes the provided data.

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.

close

void close()
    throws java.io.IOException

Closes the sink.

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

Throws:

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