Public predicates

.. index:: predicate/2 .. _caller_diagram/1::predicate/2:

predicate/2 ^^^^^^^^^^^^^^^

Creates a caller diagram for the given predicate or non-terminal using the specified options. Predicates are specified as Entity::Name/Arity. Non-terminals are specified as Entity::Name//Arity.

| Compilation flags: | static

| Template: | predicate(QualifiedIndicator,Options) | Mode and number of proofs: | predicate(+qualified_predicate_indicator,+list(compound)) - one

---

.. index:: predicate/1 .. _caller_diagram/1::predicate/1:

predicate/1 ^^^^^^^^^^^^^^^

Creates a caller diagram for the given predicate using default options. Predicates are specified as Entity::Name/Arity. Non-terminals are specified as Entity::Name//Arity.

| Compilation flags: | static

| Template: | predicate(QualifiedIndicator) | Mode and number of proofs: | predicate(+qualified_predicate_indicator) - one

---

Protected predicates

(no local declarations; see entity ancestors if any)

Private predicates

.. index:: included_caller_/1 .. _caller_diagram/1::included_caller_/1:

included_caller_/1 ^^^^^^^^^^^^^^^^^^^^^^

Table of callers already included in the diagram.

| Compilation flags: | dynamic

| Template: | included_caller_(Caller) | Mode and number of proofs: | included_caller_(?qualified_predicate_indicator) - zero_or_more | included_caller_(?predicate_indicator) - zero_or_more

---
