Interface CollectionCache

All Known Implementing Classes:

TupleCache

public interface CollectionCache

This interface represents a cache for TupleCollection objets.

Method Summary

boolean	contains(int index) Does the cache contains Object ranked int of the associated Objects to be cached.
void	destroy() Reinitializes the internal structure of the cache.
long	getCapacity()
Tuple	getTuple(int tupleIndex)
void	initialize() Creates the internal structure of the cache.
boolean	isCanInsert() Are insertions possible (is policy dependent: example may require to free the cache before insertion).
boolean	putTuple(int indexTuple, Tuple t)
void	setCanInsert(boolean canInsert) This method allow stop or no inserting objetcs in the cache.
java.util.Iterator	tupleIndexIterator() Returns an iterator over the indexes of the Objects which are present in the cache.
