.extend_predicate_method_and_define_bang_method(mod, id) ⇒ Object

Extends a given predicate method and defines a bang method for it. You should never call this method yourself, it is called either from RConditions#extend_predicate_methods_and_define_bang_methods, or from Module#method_added or Object#singleton_method_added which are extended by RConditions.

  • mod – the module on which the method is defined.

  • id – the name of the method.

.extend_predicate_methods_and_define_bang_methods ⇒ Object

Extends almost all predicate methods and defines bang methods for them. You should never call this method yourself, it is called automatically when RConditions is required. To prevent it from being called, set ::RCONDITIONS_ONLY_FOR_NEW_METHODS to true before requiring RConditions.
