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:
-
query Input to the external source. answer Output of the external source.
Reimplemented from PluginAtom.
