## org.apache.struts2.jasper.xmlparser
Class XMLStringBuffer

    java.lang.Object
      org.apache.struts2.jasper.xmlparser.XMLString
          org.apache.struts2.jasper.xmlparser.XMLStringBuffer

    public class XMLStringBuffer

extends XMLString

XMLString is a structure used to pass character arrays. However, XMLStringBuffer is a buffer in which characters can be appended and extends XMLString so that it can be passed to methods expecting an XMLString object. This is a safe operation because it is assumed that any callee will not modify the contents of the XMLString structure.

The contents of the string are managed by the string buffer. As characters are appended, the string buffer will grow as needed.

Note: Never set the `ch`, `offset`, and `length` fields directly. These fields are managed by the string buffer. In order to reset the buffer, call `clear()`.
