Test if no more chunks are left on stack.

peek

public IOChunk peek()

List chunk on top of stack.

pop

public IOChunk pop()
            throws java.io.IOException

Pop a chunk, and write content to parent chunk or the final output.

push

public void push(IOChunk chunk)

Push chunk on stack. May set the isLittleEndian flag.

close

public void close()
           throws java.io.IOException
