virtual void TestCycleAtom::retrieve ( const Query query,
Answer answer 
) [inline, virtual]

Retrieve answer to a query (external computation happens here).

This function implements the external atom computation without customized learning functions.

Answer tuples must conform to the content of the pattern tuple in Query:

  • they must contain the same number of terms as pattern
  • constants in pattern must match constants in answer tuples
  • variables in pattern must be replaced by constants in answer tuples

See also documentation of Query and Answer classes.

If both retrieve(const Query& query, Answer& answer) and retrieve(const Query& query, Answer& answer, NogoodContainerPtr nogoods) are overridden, the latter takes over precedence.

Parameters:
queryInput to the external source.
answerOutput of the external source.

Reimplemented from PluginAtom.
