Class MemSortedSetFactory

java.lang.Object
  org.jrdf.set.MemSortedSetFactory

All Implemented Interfaces:

SortedSetFactory

public class MemSortedSetFactory
extends Object
implements SortedSetFactory

An in memory implementation that uses TreeSets and a small number of known types: Triples and PredicateNodes.

Constructor Summary

MemSortedSetFactory()

Method Summary

void	close() Close any resources used by the factory - possibly database connections, file handles and the like.
<T> SortedSet<T>	createSet(Class<T> clazz) Creates a sorted set for known type.
<T> SortedSet<T>	createSet(Class<T> clazz, Comparator<?> comparator) Creates a sorted set for a known type with a given comparator.

public MemSortedSetFactory()

Method Detail

createSet

public <T> SortedSet<T> createSet(Class<T> clazz)

Description copied from interface: SortedSetFactory

Creates a sorted set for known type. The supported types depend on the implementation - current implementations support types such as Triple and PredicateNode. Otherwise, it will produce a sorted set without a comparator - which will need to be added later.

Specified by:

createSet in interface SortedSetFactory

Parameters:

clazz - The type of set to create.

Returns:

A sorted set.

createSet

public <T> SortedSet<T> createSet(Class<T> clazz,
                                  Comparator<?> comparator)

Description copied from interface: SortedSetFactory

Creates a sorted set for a known type with a given comparator. This allows non-supported types to be added. This is optional and may not be supported by all implementations.

Specified by:

createSet in interface SortedSetFactory

Parameters:

clazz - The type of set to create.

comparator - The comparator to use to determine the sort order.

Returns:

A sorted set.

close

public void close()

Description copied from interface: SortedSetFactory

Close any resources used by the factory - possibly database connections, file handles and the like. It is expected that a factory used that is not close may cause resource leaks.

Specified by:

close in interface SortedSetFactory
