Class XML11Char


  • public class XML11Char
    extends 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.

    • Method Detail

      • isXML11Space

        public static boolean isXML11Space​(int c)
        Returns true if the specified character is a space character as amdended in the XML 1.1 specification.
        Parameters:
        c - The character to check.
      • isXML11Valid

        public static boolean isXML11Valid​(int c)
        Returns true if the specified character is valid. This method also checks the surrogate character range from 0x10000 to 0x10FFFF.

        If the program chooses to apply the mask directly to the XML11CHARS array, then they are responsible for checking the surrogate character range.

        Parameters:
        c - The character to check.
      • isXML11Invalid

        public static boolean isXML11Invalid​(int c)
        Returns true if the specified character is invalid.
        Parameters:
        c - The character to check.
      • isXML11ValidLiteral

        public static boolean isXML11ValidLiteral​(int c)
        Returns true if the specified character is valid and permitted outside of a character reference. That is, this method will return false for the same set as isXML11Valid, except it also reports false for "control characters".
        Parameters:
        c - The character to check.
      • isXML11Content

        public static boolean isXML11Content​(int c)
