Class XML11Char

  • public class XML11Char
extends java.lang.Object
    This class defines the basic properties of characters in XML 1.1. The data in this class can be used to verify that a character is a valid XML 1.1 character or if the character is a space, name start, or name character. A series of convenience methods are supplied to ease the burden of the developer. Using the character as an index into the XML11CHARS array and applying the appropriate mask flag (e.g. MASK_VALID), yields the same results as calling the convenience methods. There is one exception: check the comments for the isValid method for details. Taken from org.apache.xerces.util.XML11Char.java
