public class StringBuilderWriter extends Writer implements Serializable
Writer implementation that outputs to a StringBuilder.
NOTE: This implementation, as an alternative to
java.io.StringWriter, provides an un-synchronized
(i.e. for use in a single thread) implementation for better performance.
For safe usage with multiple Threads then
java.io.StringWriter should be used.
