Class BufferEditor

java.lang.Object

org.fusesource.hawtbuf.AbstractVarIntSupport

org.fusesource.hawtbuf.BufferEditor

Direct Known Subclasses:

BufferEditor.BigEndianBufferEditor, BufferEditor.LittleEndianBufferEditor

public abstract class BufferEditor
extends AbstractVarIntSupport

Used to write and read primitives to and from a Buffer. Reads and writes are done at the buffers offset. Every read and write increases the buffer's offset and decreases the buffer's length.

Bounds checking are only performed when assertions are enabled on the JVM. It's up to you to make sure there is enough data/space in the buffer to do the read or write.
