FunctionCall
typeCheck
??? FunctionCall
visitor
- an expression visitorcontextItemType
- the static type of "." at the point where this expression is invoked.
The parameter is set to null if it is known statically that the context item will be undefined.
If the type of the context item is not known statically, the argument is set to
Type.ITEM_TYPE
XPathException
- if an error is discovered during this phase
(typically a type error)public Item evaluateItem(XPathContext context) throws XPathException

in
- the string to be translatedmap
- index built at compile time, mapping input characters to output characters. The map returns
-1 for a character that is to be deleted from the input string, Integer.MAX_VALUE for a character that is
to remain intact
