java.lang.Objectjava.io.Writer
javax.servlet.jsp.JspWriter
org.apache.jasper.runtime.JspWriterImpl
public class JspWriterImpl
Write text to a character-output stream, buffering characters so as to provide for the efficient writing of single characters, arrays, and strings. Provide support for discarding for the output that has been buffered. This needs revisiting when the buffering problems in the JSP spec are fixed -akv

Ordinarily this method stores characters from the given array into
this stream's buffer, flushing the buffer to the underlying stream as
needed. If the requested length is at least as large as the buffer,
however, then this method will flush the buffer and write the characters
directly to the underlying stream. Thus redundant
DiscardableBufferedWriters will not copy data unnecessarily.
