All known Subclasses: org.apache.xpath.functions.FuncConcat,
| FunctionMultiArgs | | public class FunctionMultiArgs extends Function3Args (Code) | | Base class for functions that accept an undetermined number of multiple
arguments.
|
| Method Summary | |
| public void | callArgVisitors(XPathVisitor visitor)
| | public boolean | canTraverseOutsideSubtree()
Tell if this expression or it's subexpressions can traverse outside
the current subtree. | | public void | checkNumberArgs(int argNum)
Check that the number of arguments passed to this function is correct. | | public boolean | deepEquals(Expression expr)
| | 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. | | public Expression[] | getArgs()
Return an expression array containing arguments at index 3 or greater. | | protected void | reportWrongNumberArgs()
Constructs and throws a WrongNumberArgException with the appropriate
message for this function object. | | public void | setArg(Expression arg, int argNum)
Set an argument expression for a function. |
| m_args | | Expression[] m_args(Code) | | Argument expressions that are at index 3 or greater.
|
| serialVersionUID | | final static long serialVersionUID(Code) | | |
| canTraverseOutsideSubtree | | public boolean canTraverseOutsideSubtree()(Code) | | Tell if this expression or it's subexpressions can traverse outside
the current subtree.
true if traversal outside the context node's subtree can occur. |
| checkNumberArgs | | public void checkNumberArgs(int argNum) throws WrongNumberArgsException(Code) | | 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 - |
| fixupVariables | | public void fixupVariables(java.util.Vector vars, int globalsSize)(Code) | | 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). |
| getArgs | | public Expression[] getArgs()(Code) | | Return an expression array containing arguments at index 3 or greater.
An array that contains the arguments at index 3 or greater. |
| reportWrongNumberArgs | | protected void reportWrongNumberArgs() throws WrongNumberArgsException(Code) | | Constructs and throws a WrongNumberArgException with the appropriate
message for this function object. This class supports an arbitrary
number of arguments, so this method must never be called.
throws:
WrongNumberArgsException - |
| setArg | | public void setArg(Expression arg, int argNum) throws WrongNumberArgsException(Code) | | Set an argument expression for a function. This method is called by the
XPath compiler.
Parameters:
arg - non-null expression that represents the argument.
Parameters:
argNum - The argument number index.
throws:
WrongNumberArgsException - If a derived class determines that thenumber of arguments is incorrect. |
