public class CodepointEqual extends SystemFunction implements Callable
Compares two strings using the Unicode codepoint collation. (The function was introduced specifically to allow URI comparison: URIs are promoted to strings when necessary.)

Callablecall in interface Callablecall in interface Functioncontext - 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.
