Class StringBufferWriter

  • All Implemented Interfaces:
    java.io.Closeable, java.io.Flushable, java.lang.Appendable, java.lang.AutoCloseable
    public class StringBufferWriter
extends java.io.Writer
    This class codes around a silly limitation of StringWriter which doesn't allow a StringBuffer to be passed in as a constructor for some bizarre reason. So we replicate the behaviour of StringWriter here but allow a StringBuffer to be passed in.
