Package org.apache.uima.cas.impl
Class FSIndexRepositoryImpl
java.lang.Object
org.apache.uima.cas.impl.FSIndexRepositoryImpl
- All Implemented Interfaces:
FSIndexRepositoryMgr
,FSIndexRepository
,LowLevelIndexRepository
public class FSIndexRepositoryImpl
extends Object
implements FSIndexRepositoryMgr, LowLevelIndexRepository
There is one instance of this class per CAS View.
Some parts of the data here are shared between all views of a CAS.
Many things refer to specific types, and their associated Java Cover classes.
Java impl classes are always used for each type;
If there is no JCas cover class defined for a type, then
the most specific superclass which has a JCas defined class is used;
this is the class TOP or one of its subclasses.
Generic typing:
User facing APIs can make use of the (JCas) Java cover types, for indexes and iterators over them
The general generic type used is typically written here as T extends FeatureStructure, where
FeatureStructure is the super interface of all JCas types.
APIs having no reference to Java cover types (i.e., low level iterators) are not generic, unless
they are needed to be to pass along the associated type to other APIs.
