Functions
-------------------------------------------------------------------------------

.. cpp:function:: data_expression_vector mcrl2::data::enumerate_expressions(const sort_expression &s, const data_specification &dataspec, const Rewriter &rewr, enumerator_identifier_generator &id_generator)
  
  Returns a vector with all expressions of sort s. 

  
  
  **Parameters:**

  * **s** A sort expression. 

  * **dataspec** The data specification defining the terms of sort s. 

  * **rewr** A rewriter to be used to simplify terms and conditions. 

  * **id_generator** An identifier generator used to generate new names for variables.


It is assumed that the sort s has only a finite number of elements. 

.. cpp:function:: data_expression_vector mcrl2::data::enumerate_expressions(const sort_expression &s, const data_specification &dataspec, const Rewriter &rewr)
  
  Returns a vector with all expressions of sort s. 

  
  
  **Parameters:**

  * **s** A sort expression. 

  * **dataspec** The data specification defining the terms of sort s. 

  * **rewr** A rewriter to be used to simplify terms and conditions.


It is assumed that the sort s has only a finite number of elements.

.. cpp:function:: bool mcrl2::data::detail::compute_finite_function_sorts(const function_sort &sort, enumerator_identifier_generator &id_generator, const data::data_specification &dataspec, Rewriter datar, data_expression_vector &result, variable_list &function_parameter_list)
  
  Computes the elements of a finite function sort, and puts them in result. If there are too many elements, false is returned. 

  

.. cpp:function:: bool mcrl2::data::detail::compute_finite_set_elements(const container_sort &sort, const data_specification &dataspec, Rewriter datar, MutableSubstitution &sigma, data_expression_vector &result, enumerator_identifier_generator &id_generator)
  
  Computes the elements of a finite set sort, and puts them in result. If there are too many elements, false is returned.
