public Expression typeCheck(StaticContext env, ItemType contextItemType) throws XPathException
FunctionCall
typeCheck
in interface Expression
typeCheck
in class FunctionCall
env
- the static context of the expressioncontextItemType
- 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
StaticError
- if an error is discovered during this phase
(typically a type error)
