Class ChunkyByteInput

java.lang.Object

java.io.InputStream

org.jboss.as.process.protocol.ChunkyByteInput

All Implemented Interfaces:

Closeable, AutoCloseable, org.jboss.marshalling.ByteInput

public class ChunkyByteInput
extends InputStream
implements org.jboss.marshalling.ByteInput

Byte input implementation that reads bytes in chunks. Each chunk is started with a CHUNK_START header followed by the length of the chunk. At the end of all the chunks it will run into a END byte, which will appear as the end of the stream. This is used when you need to ensure a consumer of the input can not read more than necessary. This is handy if the consumer of the stream is prone to over-buffering. Note this will only work for byte streams that were written using a ChunkyByteOutput.
