Examples of MemoryByteArrayOutputStream

org.jfree.report.util.MemoryByteArrayOutputStream
A string writer that is able to write large amounts of data. The original StringWriter contained in Java doubles its buffersize everytime the buffer overflows. This is nice with small amounts of data, but awfull for huge buffers. @author Thomas Morgner
