viewable_type(++ViewableName, ?Type)

ViewableName

A string or atom: the name of an existent viewable

Type

The type of the viewable.

Description

NOTE:When there are no registered visualisation clients, this predicate fails with all arguments, and has no effect.

If ViewableName is the name of an existent viewable, Type is unified with its type. See viewable_create/3 for a discussion of valid viewable types.

Fail Conditions

Resatisfiable

Exceptions

(4) instantiation fault

ViewableName is not a string or an atom

	viewable_create(v1, []([](R,S), [](Q,W)), 
			array([fixed, fixed], any)), 
	viewable_type(v1, X).

        [gives X = array([fixed, fixed], any)]


	Failure:

	viewable_create(v1, []([](R,S), [](Q,W)), 
		array([fixed, fixed], any)), 
	viewable_type(v1, q).


	Exceptions raised:

	viewable_create(v1, []([](R,S), [](Q,W)), 
		array([fixed, fixed], any)), 
	viewable_type(123, _).
