Examples of org.mortbay.io.Buffer

org.mortbay.io.Buffer
Byte Buffer interface. This is a byte buffer that is designed to work like a FIFO for bytes. Puts and Gets operate on different pointers into the buffer and the valid _content of the buffer is always between the getIndex and the putIndex. This buffer interface is designed to be similar, but not dependant on the java.nio buffers, which may be used to back an implementation of this Buffer. The main difference is that NIO buffer after a put have their valid _content before the position and a flip is required to access that data. For this buffer it is always true that: markValue <= getIndex <= putIndex <= capacity @author gregw @version 1.0
