Examples of org.apache.isis.core.metamodel.spec.ObjectSpecification

org.apache.isis.core.metamodel.spec.ObjectSpecification
Represents an entity or value (cf {@link java.lang.Class}) within the metamodel.
As specifications are cyclic (specifically a class will reference its subclasses, which in turn reference their superclass) they need be created first, and then later work out its internals. Hence we create {@link ObjectSpecification}s as we need them, and then introspect them later.

    /**
     * API: Return specification.

    @Override
    public ObjectSpecification loadSpecification(final Class<?> type) {
        final ObjectSpecification spec = internalLoadSpecification(type);
        if(spec == null) {
            return null;
        }
        if(getCache().isInitialized()) {
            // umm.  It turns out that anonymous inner classes (eg org.estatio.dom.WithTitleGetter$ToString$1)
            // don't have an ObjectSpecId; hence the guard.
            if(spec.containsDoOpFacet(ObjectSpecIdFacet.class)) {
                ObjectSpecId specId = spec.getSpecId();
                if (getCache().getByObjectType(specId) == null) {
