FunctionMultiArgs
public FunctionMultiArgs()
getArgs
public Expression[] getArgs()
- Return an expression array containing arguments at index 3 or greater.
- Returns:
- An array that contains the arguments at index 3 or greater.
setArg
public void setArg(Expression arg,
int argNum)
throws WrongNumberArgsException
- Set an argument expression for a function. This method is called by the
XPath compiler.
- Parameters:
arg
- non-null expression that represents the argument.argNum
- The argument number index.- Throws:
- WrongNumberArgsException - If a derived class determines that the
number of arguments is incorrect.
- Overrides:
- setArg in class Function3Args
fixupVariables
public 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.
- 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).- Overrides:
- fixupVariables in class Function3Args
checkNumberArgs
public void checkNumberArgs(int argNum)
throws WrongNumberArgsException
- Check that the number of arguments passed to this function is correct.
- Parameters:
argNum
- The number of arguments that is being passed to the function.- Throws:
- WrongNumberArgsException -
- Overrides:
- checkNumberArgs in class Function3Args
canTraverseOutsideSubtree
public boolean canTraverseOutsideSubtree()
- Tell if this expression or it's subexpressions can traverse outside
the current subtree.
- Returns:
- true if traversal outside the context node's subtree can occur.
- Overrides:
- canTraverseOutsideSubtree in class Function3Args
callArgVisitors
public void callArgVisitors(XPathVisitor visitor)
- Overrides:
- callArgVisitors in class Function3Args
- See Also:
XPathVisitable.callVisitors(ExpressionOwner, XPathVisitor)
deepEquals
public boolean deepEquals(Expression expr)
- Overrides:
- deepEquals in class Function3Args
- See Also:
Expression.deepEquals(Expression)
