Class ChunkyByteOutput

java.lang.Object

java.io.OutputStream

org.jboss.as.process.protocol.ChunkyByteOutput

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable, org.jboss.marshalling.ByteOutput

public class ChunkyByteOutput
extends OutputStream
implements org.jboss.marshalling.ByteOutput

Byte output implementation that writes the bytes out in chunks. Each invocation of flush will first write a CHUNK_START header followed by the size of the chunk being flushed. Once the closed, this will write out a END byte. This should be used to write data that can be read by a ChunkyByteInput to ensure the reader can not read more than available. This is handy if the consumer of the stream is prone to over-buffering.

Method Detail

write

public void write(int v)
           throws IOException

Specified by:

write in interface org.jboss.marshalling.ByteOutput

Specified by:

write in class OutputStream

Throws:

IOException

write

public void write(byte[] bytes)
           throws IOException

Specified by:

write in interface org.jboss.marshalling.ByteOutput

Overrides:

write in class OutputStream

Throws:

IOException

write

public void write(byte[] bytes,
                  int off,
                  int len)
           throws IOException

Specified by:

write in interface org.jboss.marshalling.ByteOutput

Overrides:

write in class OutputStream

Throws:

IOException

close

public void close()
           throws IOException

Flushes the current buffer then write a END byte. This will not close the underlying byte output

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Overrides:

close in class OutputStream

Throws:

IOException

flush

public void flush()
           throws IOException

Writes a CHUNK_START header followed by the size of chunk being flushed followed by the data being flushed. It will then flush the underlying byte output.

Specified by:

flush in interface Flushable

Overrides:

flush in class OutputStream

Throws:

IOException

writeInt

public void writeInt(int i)
              throws IOException

Throws:

IOException
