public class XMLChar extends Object
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.

This is an optimization for the inner loop of character scanning.
Parameters: c The supplemental character to "split".
Parameters: c The character to check.
Parameters: c The character to check.
Parameters: c The character to check.
Parameters: c The character to check.
Parameters: c The character to check.
Parameters: c The character to check.
Parameters: c The character to check.
Parameters: c The character to check.
Parameters: c The character to check.
Parameters: c The character to check.
Parameters: c The character to check.
Parameters: c The character to check.
If the program chooses to apply the mask directly to the
CHARS
array, then they are responsible for checking
the surrogate character range.
Parameters: c The character to check.
Parameters: ianaEncoding The IANA encoding name.
Parameters: javaEncoding The Java encoding name.
Parameters: name string to check
Returns: true if name is a valid Name
Parameters: ncName string to check
Returns: true if name is a valid NCName
Parameters: nmtoken string to check
Returns: true if nmtoken is a valid Nmtoken
Parameters: c The supplemental character to "split".
Parameters: h The high surrogate. l The low surrogate.
