- the expression visitorcontextInfo
- information about the context itemarguments
- the supplied arguments to the function call. Note: modifying the contents
of this array should not be attempted, it is likely to have no effect.XPathException

Callable
context
- the dynamic evaluation contextarguments
- the values of the arguments, supplied as Sequences.
Generally it is advisable, if calling iterate() to process a supplied sequence, to
call it only once; if the value is required more than once, it should first be converted
to a GroundedValue
by calling the utility method
SequenceTool.toGroundedValue().
If the expected value is a single item, the item should be obtained by calling
Sequence.head(): it cannot be assumed that the item will be passed as an instance of
Item
or AtomicValue
.
It is the caller's responsibility to perform any type conversions required to convert arguments to the type expected by the callee. An exception is where this Callable is explicitly an argument-converting wrapper around the original Callable.
