Method Detail

returnsType

public int returnsType()
Description copied from interface: Expression
The static return type of the expression. This method should return one of the type constants defined in class Type. If the return type cannot be determined statically, return Type.ITEM.

Specified by:
returnsType in interface Expression
Overrides:
returnsType in class Function

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
Parameters:
args -
contextSequence -
Throws:
XPathException
