PrimaryKey
public PrimaryKey(DB m4Db)
- Constructor for PrimaryKey.
- Parameters:
m4Db
- The DB object
getObjectsInNamespace
protected java.util.Collection getObjectsInNamespace(java.lang.Class typeOfObjects)
throws M4Exception
- Description copied from class:
M4Data
- This method returns the objects of the specified type that
form a namespace in the scope of this M4Data object. For example,
a Concept's namespace for the type BaseAttribute is the Collection
of all BaseAttributes for this Concept. Many M4Data objects never
have a namespace, they return
null
. If a namespace could
exist but doesn't, an empty Collection is returned.
- Specified by:
getObjectsInNamespace
in class M4Data
- Parameters:
typeOfObjects
- the type of objects that form the namespace
- Returns:
- a Collection of objects of type
typeOfObjects
,
or null
.
- Throws:
M4Exception
- See Also:
M4Data.getObjectsInNamespace(Class)
