public Class XML11Char

extends Object
Class Inheritance
Imports
java.util.Arrays
THIS IS A COPY OF THE XERCES-2J CLASS com.sun.org.apache.xerces.internal.utls.XMLChar 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

isXML11Contentback to summary
public static boolean isXML11Content(int c)

Returns true if the specified character can be considered content in an external parsed entity.

Parameters
c:int

The character to check.

isXML11InternalEntityContentback to summary
public static boolean isXML11InternalEntityContent(int c)

Returns true if the specified character can be considered content in an internal parsed entity.

Parameters
c:int

The character to check.

Returns true if the specified character is invalid.

Parameters
c:int

The character to check.

Returns true if the specified character is a valid name character as defined by production [4a] in the XML 1.1 specification.

Parameters

The character to check.

isXML11NameHighSurrogateback to summary
public static boolean isXML11NameHighSurrogate(int c)

Returns whether the given character is a valid high surrogate for a name character. This includes all high surrogates for characters [0x10000-0xEFFFF]. In other words everything excluding planes 15 and 16.

Parameters
