public class StringBuilderWriter extends Writer
Copied from https://github.com/apache/commons-io/blob/master/src/main/java/org/apache/commons/io/output/StringBuilderWriter.java 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.
