public interface WebAnnotations
Main link for web module annotation related services. The annotation services type acts as a Future, as a Future , and as a Future , with the sharing of a single class source between the other two futures. Current references are from: com.ibm.ws.webcontainer.osgi.DeployedModImpl.adapt(Class ) That adapt implementation provides three entries into the annotation services: - DeployedModule adapt to ClassSource_Aggregate
- DeployedModule adapt to AnnotationTargets_Targets
- DeployedModule adapt to ClassSource
Note on fragment paths:
These are specified through a complete, ordered, list, and through the partition of that list into included partial and excluded locations. Seed locations are fragment jars which are neither metadata-complete nor were excluded because they were omitted from an absolute ordering. Partial locations are those which are metadata-complete and not omitted from an absolute ordering. Excluded locations are those which were omitted because an absolute ordering is specified, and no others element is specified. The excluded locations are those which were not specified in the absolute ordering explicit listing.
Note that exclusion has precedence over metadata-complete.
Fragment paths are relative to the "WEB-INF/lib" folder, not to the rot web module container.
Included locations are scanned for annotations and for class relationship information. Partial locations are scanned only for class relationship information. Excluded locations are scanned only for class relationship information, and only as required to complete class relationship information for referenced classes.
Class relationship information is the class to superclass and the class to implements relationships.

-
isPartialClass
boolean isPartialClass(java.lang.String className) throws com.ibm.wsspi.adaptable.module.UnableToAdaptException
Tell if the target class was scanned from a partial (metadata-complete) fragment.
- Parameters:

openInfoStore
void openInfoStore() throws com.ibm.wsspi.adaptable.module.UnableToAdaptException
Helper to open the info store. This is recommended if many calls are expected to

com.ibm.wsspi.adaptable.module.UnableToAdaptException
- Thrown if the open failed. Often, because of a problem opening a ZIP or a JAR file.
-
