Method Detail

analyze

public void analyze(AnalyzeContextInfo contextInfo)
             throws XPathException
Description copied from interface: Expression
Statically analyze the expression and its subexpressions. During the static analysis phase, the query engine can detect unknown variables and some type errors.

Specified by:
analyze in interface Expression
Overrides:
analyze in class Function
Throws:
XPathException

eval

public Sequence eval(Sequence[] args,
                     Sequence contextSequence)
              throws XPathException
Description copied from class: BasicFunction
Process the function. All arguments are passed in the array args. The number of arguments, their type and cardinality have already been checked to match the function signature.

Specified by:
eval in class BasicFunction
Throws:
XPathException
