pce_thread(-Thread) is det

True if Thread is the Prolog thread that runs the graphics message loop.

See also

- pce_dispatch/1.

 in_pce_thread_sync(:Goal) is semidet

Same as in_pce_thread/1, but wait for Goal to be completed. Success depends on the success of executing Goal. If Goal throws an exception, this exception is re-thrown by in_pce_thread/1.

Possible bindings of Goal are returned, but be aware that the term has been copied. If in_pce_thread_sync/1 is called in the thread running pce, it behaves as once/1.

 prolog:locate_clauses(Term, Refs)[multifile]

Locate a list of clause-references from a method-specification like Class->Method.

see library(listing).

Re-exported predicates

The following predicates are exported from this file while their implementation is defined in imported modules or non-module files loaded by this module.

 pce_prolog_class(?ClassName:atom) is nondet

 pce_prolog_class(?ClassName:atom, ?SuperName:atom) is nondet

Is true if ClassName refers to a class defined in Prolog with the given superclass.

 pce_global(+Object, :Goal) is det

Register Goal to be a goal that creates @Reference

 pce_prolog_class(?ClassName:atom) is nondet

 pce_prolog_class(?ClassName:atom, ?SuperName:atom) is nondet

Is true if ClassName refers to a class defined in Prolog with the given superclass.

 pce_compiling(-ClassName)

External function to get the current classname

 pce_autoload_all

Load all classes declared using the pce_autoload/2 directive. Useful for debugging purposes.

 pce_catch_error(?Errors, :Goal)

Run goal, fail silently on indicated errors. If the first argument is a variable, any error will be catched.

 pce_begin_class_definition(+ClassName, +Meta, +Super, +Summary)

Dummy to allow cross-referencing and other tools to locate class-definitions after term-expansion.

 pce_autoload(+ClassName, +FileSpec)

States class `ClassName' can be created by loading the Prolog file `FileSpec'. This will actually be done if either the class is actually needed by PCE or pce_autoload_all/0 is called.
