built-in method

representation_error/1

Description

representation_error(Flag)

Throws a representation error. Used when some representation limit is exceeded. For example, trying to construct a compound term that exceeds the maximum arity supported by the backend Prolog system. This built-in method is declared private and thus cannot be used as a message to an object. Calling this predicate is equivalent to the following sequence of goals:

...,
context(Context),
throw(error(representation_error(Flag), Context)).

This allows the user to generate errors in the same format used by the runtime.

Possible values for Flag include:

  • character

  • character_code

  • in_character_code

  • max_arity

  • max_integer

  • min_integer

  • acyclic_term

  • lambda_parameters

  • entity_prefix
