com.cloudhopper.commons.util.FastByteArrayOutputStream
ava2s.com/Code/Java/File-Input-Output/AspeedyimplementationofByteArrayOutputStream.htm A speedy implementation of ByteArrayOutputStream. It's not synchronized, and it does not copy buffers when it's expanded. There's also no copying of the internal buffer if it's contents is extracted with the writeTo(stream) method. @author Rickard berg @author Brat Baker (Atlassian) @author Alexey @version $Date: 2008-01-19 10:09:56 +0800 (Sat, 19 Jan 2008) $ $Id: FastByteArrayOutputStream.java 3000 2008-01-19 02:09:56Z tm_jee $
