Class XML11Char
java.lang.Objectorg.apache.xerces.util.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.

| Constructor Detail |
XML11Char
public XML11Char()
| 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.
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
XML11CHARSarray, then they are responsible for checking the surrogate character range.
isXML11Invalid
public static boolean isXML11Invalid(int c)
- Returns true if the specified character is invalid.
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".
isXML11Content
public static boolean isXML11Content(int c)
- Returns true if the specified character can be considered
content in an external parsed entity.
isXML11InternalEntityContent
public static boolean isXML11InternalEntityContent(int c)
- Returns true if the specified character can be considered
content in an internal parsed entity.
isXML11NameStart
public static boolean isXML11NameStart(int c)
- Returns true if the specified character is a valid name start
character as defined by production [4] in the XML 1.1
specification.
isXML11Name
public static boolean isXML11Name(int c)
- Returns true if the specified character is a valid name
character as defined by production [4a] in the XML 1.1
specification.
isXML11NCNameStart
public static boolean isXML11NCNameStart(int c)
- Returns true if the specified character is a valid NCName start
character as defined by production [4] in Namespaces in XML
1.1 recommendation.
isXML11NCName
public static boolean isXML11NCName(int c)
- Returns true if the specified character is a valid NCName
character as defined by production [5] in Namespaces in XML
1.1 recommendation.
isXML11NameHighSurrogate
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.
isXML11ValidName
public static boolean isXML11ValidName(java.lang.String name)
- Check to see if a string is a valid Name according to [5]
in the XML 1.1 Recommendation
isXML11ValidNCName
public static boolean isXML11ValidNCName(java.lang.String ncName)
- Check to see if a string is a valid NCName according to [4]
from the XML Namespaces 1.1 Recommendation
isXML11ValidNmtoken
public static boolean isXML11ValidNmtoken(java.lang.String nmtoken)
- Check to see if a string is a valid Nmtoken according to [7]
in the XML 1.1 Recommendation
