call
Call of in-scope-prefixes- Parameters:
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 methd 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
orAtomicValue
.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.
- Returns:
- the sequence of prefixes
- Throws:
XPathException
- if a dynamic error occurs
