Class StandardContextCollectorBuilder

  • public class StandardContextCollectorBuilder
extends Object
    A convenience class allowing to describe behavior of a scope collector using a set of simple rules and then build an instance of IScopeCollector in compliance with these rules.
    See the usage example below.
     ICaseSpecificScopeCollector onFeatureBChangeScopeCollector = ...

 IScopeCollector scopeCollector =
     new ScopeCollectorBuilder(SOME_OBJECT_TYPE)
         .onAssociation().compute(PART_A, PART_B)
         .onChange(FEATURE_A)
             .compute(PART_B)
             .flowChildren(FEATURE_C).compute(PART_A, PART_B)
         .onChange(FEATURE_B).compute(onFeatureBChangeScopeCollector)
         .build();
