Method Detail

execute

public XObject execute(XPathContext xctxt)
                throws javax.xml.transform.TransformerException
Execute the function. The function must return a valid object.

Overrides:
execute in class Function
Parameters:
xctxt - The current execution context.
Returns:
A valid XObject.
Throws:
javax.xml.transform.TransformerException

fixupVariables

public void fixupVariables(java.util.Vector vars,
                           int globalsSize)
No arguments to process, so this does nothing.

Specified by:
fixupVariables in class Expression
Parameters:
vars - List of QNames that correspond to variables. This list should be searched backwards for the first qualified name that corresponds to the variable reference qname. The position of the QName in the vector from the start of the vector will be its position in the stack frame (but variables above the globalsTop value will need to be offset to the current stack frame).
