Class XMLChar
java.lang.Object
org.htmlunit.cyberneko.xerces.util.XMLChar
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.
