Method Summary

boolean	insert(SubjectNode s, PredicateNode p, ObjectNode o) Add a new triple to the graph.
boolean	insert(Triple triple) Add a new triple to the graph.
Graph	mergeInto(Graph g) Adds the contents of another graph to this one, creating new blank nodes as required (not re-using the blank nodes from the original graph).

Method Detail

insert

boolean insert(SubjectNode s,
               PredicateNode p,
               ObjectNode o)

Add a new triple to the graph.

Parameters:

s - The subject of the triple to add.

p - The predicate of the triple to add.

o - The object of the triple to add.

Returns:

true if the triple did not exist in the graph.

insert

boolean insert(Triple triple)

Add a new triple to the graph.

Parameters:

triple - The complete triple to add.

Returns:

true if the triple was already in the graph.

mergeInto

Graph mergeInto(Graph g)

Adds the contents of another graph to this one, creating new blank nodes as required (not re-using the blank nodes from the original graph).

Parameters:

g - The graph to merge into this one.

Returns:

The current graph, after modification.

unionInto

Graph unionInto(Graph g)

Adds the contents of another graph to this one, re-using all the blank nodes from the new graph.

Parameters:

g - The graph to merge into this one.

Returns:

The current graph, after modification.
