Template Class KnownTerm¶

Defined in File known_term.h

Class Documentation¶

template<typename Source, typename TestExpression, typename Support = InferredIntegrationSupport> class KnownTerm¶

A dependency-free FE term generated by a known source.

A frozen Observable is accepted as a source as well. In that case its existing FE operation and frozen vector are evaluated directly, so the term reuses the ordinary FE expression machinery without registering a state dependency or duplicating a field representation.
