- Direct Known Subclasses:
- FuncConcat
- public class FunctionMultiArgs
- extends Function3Args
Base class for functions that accept an undetermined number of multiple
arguments.
This class is based on an implementation from the Apache XML
Project. In future releases the XML parser, XSLT processor, and
associated classes will likely be updated to be based on a later
version of the Apache implementations. Since Apache does not guarantee
backwards compatibility between versions of their software, we cannot
guarantee backwards compatibility of any of the classes contained in
the weblogic.apache package or sub-packages.

FunctionMultiArgs
public FunctionMultiArgs()
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
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
