CollatingFunctionFixed |
bindCollation(java.lang.String collationName)
Create an instance of (a subclass of) CollatingFunctionFixed representing the underlying
function but with the collator already bound

Sequence |
call(XPathContext context,
Sequence[] args)
Invoke the function.

static java.lang.String |
expandCollationURI(java.lang.String collationName,
java.net.URI expressionBaseURI)
Expand a collation URI, which may be a relative URI reference
|
java.lang.String |
getStreamerName()
Get a name that identifies the class that can be used to evaluate this function
in streaming mode, that is, supplying one item or event at a time as it is
delivered by the parser.

Expression |
makeOptimizedFunctionCall(ExpressionVisitor visitor,
ContextItemStaticInfo contextInfo,
Expression... arguments)
Allow the function to create an optimized call based on the values of the actual arguments
