Class XMLChar

java.lang.Object
  extended byweblogic.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.

Field Detail

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.

Method Detail

highSurrogate

public static char highSurrogate(int c)
Deprecated. 
Returns the high surrogate of a supplemental character

Parameters:
c - The supplemental character to "split".

isContent

public static boolean isContent(int c)
Deprecated. 
Returns true if the specified character can be considered content.

Parameters:
c - The character to check.

isHighSurrogate

public static boolean isHighSurrogate(int c)
Deprecated. 
Returns whether the given character is a high surrogate

Parameters:
c - The character to check.

isInvalid

public static boolean isInvalid(int c)
Deprecated. 
Returns true if the specified character is invalid.

Parameters:
c - The character to check.

Deprecated. 
Returns whether the given character is a low surrogate

Parameters:

Returns true if the specified character can be considered markup. Markup characters include '<', '&', and '%'.

Parameters:
c - The character to check.

Returns true if the specified character is a valid name character as defined by production [4] in the XML 1.0 specification.

Parameters:
