Class XMLChar

    java.lang.Object
      weblogic.apache.xerces.util.XMLChar

Deprecated. please use JDK supplied XML parsers and transformers

    public class XMLChar

extends Object

This class defines the basic XML character properties. The data in this class can be used to verify that a character is a valid XML 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. Because inlining the checks can improve per character performance, the tables of character properties are public. Using the character as an index into the `CHARS` 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.

    public static final int MASK_VALID

  Deprecated.
  Valid character mask.

  See Also:
    Constant Field Values

### MASK_SPACE

    public static final int MASK_SPACE

  Deprecated.
  Space character mask.

  See Also:
    Constant Field Values

### MASK_NAME_START

    public static final int MASK_NAME_START

    Constant Field Values

### MASK_NAME

    public static final int MASK_NAME

  Deprecated.

  Deprecated.
  Pubid character mask.

  See Also:
    Constant Field Values

### MASK_CONTENT

    public static final int MASK_CONTENT

  Deprecated.
  Content character mask. Special characters are those that can be considered the start of markup, such as '<' and '&'. The various newline characters are considered special as well. All other valid XML characters can be considered content.

  This is an optimization for the inner loop of character scanning.

### XMLChar

    public XMLChar()

  Deprecated.

Method Detail

### isSupplemental

    public static boolean isSupplemental(int c)

  Deprecated.
  Returns true if the specified character is a supplemental character.

  Parameters:
    `c` - The character to check.

### supplemental

    public static int supplemental(char h,
                                   char l)

  Returns true the supplemental character corresponding to the given surrogates.

  Parameters:
    `h` - The high surrogate.
    `l` - The low surrogate.

### highSurrogate
