MergeJoinOperator

public MergeJoinOperator(AbstractDomain abstractDomain)

Create a merge operator from an abstract domain defining the join operator.

Parameters:

abstractDomain - abstract domain

Method Detail

merge

public AbstractState merge(AbstractState abstractState1,
                           AbstractState abstractState2,
                           Precision precision)

Description copied from interface: MergeOperator

The operator uses the abstractState1 to weaken abstractState2 depending on precision. Thus, it is asymmetric regarding its first two parameters. E.g., return abstractState2 for no merging. To guarantee the correct behavior of the algorithm implementations must have no side effects.
