Class xs.xs_PatternMatchLevel
java.lang.Object
|
+----xs.xs_PatternMatchLevel
- public class xs_PatternMatchLevel
- extends Object
A repository for the information about an XSL pattern which is used to
determine precedence of patterns.
The values herein are calculated once as the XSL stylesheet is parsed, to
enable efficient subsequent processing. To improve efficiency still further,
a single overall match level is also calculated, taking into account the
precendence of the constituent values. This only works if none of the
constituent values exceeds 9; if any value exceeds 9, the individual
values are compared.
Note that this class has no provision for resetting values: it assumes
values will be set once at XSL parse time, and therefore only accommodates
incrementing (increasing) values but not decrementing them.
