Detailed Description

Gather aggregate elements.

This class can also be used to derive empty aggregates. A tuple with a neutral element has to be used, which is 0/#sum/#sup depending on the type of the aggregate. Count aggregates have to be translated to sum+ aggregates beforehand.

Constructor & Destructor Documentation

StmBdAggrElem()

CppClingo::Ground::StmBdAggrElem::StmBdAggrElem ( StateBdAggr &  state, Location  loc_weight, UTermVec  tuple, ULitVec  body, size_t  num_cond, size_t  priority, ProfileNodeInternal *  node  )

inline

Construct the statement.

The first num_cond literals of the body must form the aggregate element's condition. The following literals are just used for grounding binding global variables of the aggregate and ensuring safety.
