Method Detail

check

public MatchConditions check(SchemaVariable var,
                             SVSubstitute instCandidate,
                             MatchConditions matchCond,

Description copied from interface: VariableCondition

checks if the condition for a correct instantiation is fulfilled

Specified by:

matchCond - the MatchCondition with the current matching state and in particular the SVInstantiations that are already known to be needed

services - the program information object

Returns:

modified match results if the condition can be satisfied, or null otherwise

                         java.util.List<ProgramElement> programs,
                         Services services)
