LazyFilteredAnnotationDB
Create a new DB by wrapping another with a schema.- Parameters:
name
- the name for the SBsource
- the underlying DBschema
- the schema to apply to the underlying DB to make this one
-

Method Details
-
getName
Description copied from interface:AnnotationDB
The name of this AnnotationDB.
- Specified by:
getName
in interfaceAnnotationDB
- Returns:
- the name of this AnnotationDB
-
getSchema
Description copied from interface:AnnotationDB
Get an AnnotationType that accepts all Annotation instances in this DB.
The schema should accept all Annotations in the DB. However, it may hit other Annotations. So, AnnotationType.ALL is always a valid schema. Obviously, the more retrictive it is, the more usefull it becomes for introspection.
- Specified by:
getSchema
in interfaceAnnotationDB
- Returns:
- the schema AnnotationType
-
iterator
Description copied from interface:AnnotationDB
Loop over each Annotation in this db.- Specified by:
iterator
in interfaceAnnotationDB
- Returns:
- an Iterator over each item in the DB
-
size
Description copied from interface:AnnotationDB
The number of Annotation instances in the DB.- Specified by:
size
in interfaceAnnotationDB
- Returns:
- the size of this DB
-
filter
Description copied from interface:AnnotationDB
Find all Annotation instances in this DB that are of a particular type.- Specified by:
filter
in interfaceAnnotationDB
- Parameters:
at
- the AnnotationType to match- Returns:
- an AnnotationDB with all matching Annotation instances
-
search
Description copied from interface:AnnotationDB
Find all Annotation instances in this DB and any Annotations that are child properties of these that match an AnnotationType.- Specified by:
search
in interfaceAnnotationDB
- Parameters:
at
- the AnnotationType to search with- Returns:
- an AnnotationDB with all matching Annotation instances, irregardless of how deep in the hieracy they are
