Class BootstrapAdapterFactory

  • public class BootstrapAdapterFactory
extends Object
    Counterpart for MetaAdapterFactory which creates meta-objects tuned for bootstrap purposes. NOTE. THIS IS INTERNAL API AND SHALL NOT BE USED DIRECTLY FROM USER'S CODE.

    BOOTSTRAP META OBJECTS

    Bootstrap attribute indicates whether we can rely on regular MPS infrastructure to find out details about the meta object or not. Without generated classes for meta object (i.e. concept, property, link) descriptors, we face interpreted descriptors, and as long as we describe our concepts using themselves (e.g. BaseConcept and ConceptDeclaration, what we refer to as 'bootstrap' here), we need to tell certain meta objects shall not behave like others. Ultimate example is an attempt to find out name of INamedConcept, which keeps its name in the property INamedConcept.name, where we shall not use anything but values already known (i.e. can't go to ConceptRegistry to find concept and property descriptors as they are right in the process of being initialized).

    For the time being, it's only name which is guarded from going to ConceptRegistry. Consider the example with INamedConcept. An attempt to read name of INamedConcept node triggers propertyRead notification, which requires SProperty.getName(), and without bootstrap flag, we would go to find property descriptor, and then trigger sequence of unrelated load attempts that in turn would need INamedConcept.name.

    Generally, bootstrap meta objects shall not be used, thus we keep them separate from the rest of meta objects. Don't use them unless there's bootstrap dependency you're sure is indeed bootstrap one.

    Note, we do not cache these objects as there should be few of them and they are likely get reused anyway (e.g. as static field in SNodeUtil). If not re-used, why would they be declared bootstrap, after all?
