IEStructuralFeatureValueGetter eStructuralFeatureValueGetter)

A constructor that initializes this EObjectReferenceValueCondition with the passed values. It defaults to using ConditionPolicy.ANY for the ConditionPolicy policy, the PruneHandler.NEVER for the PruneHandler and the sets resolving to true

Parameters:

reference - The EReference whose value is to be tested

valueCondition - the EObjectCondition object to use for evaluating the EReference value

eStructuralFeatureValueGetter - The IEStructuralFeatureValueGetter used to extract the value of the EReference from a given context object
