|---|---|
void |
callArgVisitors(XPathVisitor visitor)
Call the visitors for the function arguments.
|
boolean |
canTraverseOutsideSubtree()
Tell if this expression or it's subexpressions can traverse outside
the current subtree.
|
void |
checkNumberArgs(int argNum)
Check that the number of arguments passed to this function is correct.
|
boolean |
deepEquals(Expression expr)
Compare this object with another object and see
if they are equal, include the sub heararchy.
|
void |
fixupVariables(java.util.Vector vars,
int globalsSize)
This function is used to fixup variables from QNames to stack frame
indexes at stylesheet build time.
|
Expression |
getArg2()
Return the third argument passed to the function (at index 2).

public void fixupVariables(java.util.Vector vars,
int globalsSize)
fixupVariables in class Function2Argsvars - 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).public void setArg(Expression arg, int argNum) throws WrongNumberArgsException
