public KeyDefinition(PatternFinder match, Expression use, String collationName, StringCollator collation)
match
- the pattern in the xsl:key match attributeuse
- the expression in the xsl:key use attribute, or the expression that results from compiling
the xsl:key contained instructions. Note that a KeyDefinition constructed by the XSLT or XQuery parser will
always use an Expression here; however, a KeyDefinition constructed at run-time by a compiled stylesheet
or XQuery might use a simple ExpressionEvaluator that lacks all the compile-time information associated
with an ExpressioncollationName
- the name of the collation being usedcollation
- the actual collation. This must be one that supports generation of collation keys.Method Detail |
