Examples of org.jgroups.util.ByteArrayDataOutputStream

org.jgroups.util.ByteArrayDataOutputStream
Implements {@link java.io.DataOutput} over a byte[] buffer. The byte[] buffer expands when needed; however, itdoesn't double but only expands minimally, to accommodate the additional data. It is therefore recommended to always size the buffer to the actual number of bytes needed. This class is not thread safe. @author Bela Ban @since 3.5
