@Deprecated(forRemoval=true)
public class CollectionGraph
extends GraphBase

Deprecated, for removal: This API element is subject to removal in a future version.

To be removed.

A simple graph implementation that wraps a collection of triples. This is intended to be used in places where a graph is required but iteration is the only expected operation. All graph operations are supported but many are not efficient and will be slow on large collections. In these cases a memory based graph will be more efficient.

This implementation:

• Does not support deleting triples from the iterator

Constructor Details

CollectionGraph

public CollectionGraph()

Deprecated, for removal: This API element is subject to removal in a future version.

Construct an empty graph using an empty HashSet. Iterator deletion is supported.

CollectionGraph

public CollectionGraph(Collection<Triple> triples)

Deprecated, for removal: This API element is subject to removal in a future version.

Construct a graph from a collection. Iterator deletion is not supported.

Parameters:

triples - The collection of triples.

Method Details

performAdd

public void performAdd(Triple t)

Deprecated, for removal: This API element is subject to removal in a future version.

Description copied from class: GraphBase

Add a triple to the triple store. The default implementation throws an AddDeniedException; subclasses must override if they want to be able to add triples.

Specified by:

performAdd in interface GraphWithPerform

Overrides:

performAdd in class GraphBase

performDelete

public void performDelete(Triple t)

Deprecated, for removal: This API element is subject to removal in a future version.

Description copied from class: GraphBase

Remove a triple from the triple store. The default implementation throws a DeleteDeniedException; subclasses must override if they want to be able to remove triples.

Specified by:

performDelete in interface GraphWithPerform

Overrides:

performDelete in class GraphBase
