Examples of ByteArrayDataOutputStream

org.jboss.classfilewriter.util.ByteArrayDataOutputStream
DataOutputStream sub class that allows for the lazy writing of length values.
These length values are inserted into the bytes when then final bytes are read. @author Stuart Douglas
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
