Constructor Detail

SimpleImmutableGraph

public SimpleImmutableGraph(Graph Graph)

Creates a ImmutableGraph with the triples in Graph

Parameters:

Graph - the collection of triples this ImmutableGraph shall consist of

SimpleImmutableGraph

public SimpleImmutableGraph(Graph Graph,
                            boolean GraphWillNeverChange)

Creates a ImmutableGraph with the triples in Graph.

This construction allows to specify if the Graph might change in future. If GraphWillNeverChange is set to true it will assume that the collection never changes, in this case the collection isn't copied making things more efficient.

Parameters:

Graph - the collection of triples this ImmutableGraph shall consist of

GraphWillNeverChange - true if the caller promises Graph will never change
