Method Detail

removeEdge

public GraphChangeSet<VID> removeEdge(long edgeId)

Description copied from interface: GraphChangeSet

Removes an edge from the graph. If the graph doesn't have an edge with the given ID, an exception will be thrown once the graph is built.

Specified by:

removeEdge in interface GraphChangeSet<VID>

Parameters:

edgeId - the ID of the edge to be removed

Returns:

this graph change set

removeVertex

public GraphChangeSet<VID> removeVertex(VID vertexId)

Description copied from interface: GraphChangeSet

Removes a vertex from the graph. If the graph doesn't have a vertex with the given ID, an exception will be thrown once the graph is built.

Specified by:

removeVertex in interface GraphChangeSet<VID>

Parameters:

vertexId - the ID of the vertex to be removed

Returns:

this graph change set

resetEdge

public GraphChangeSet<VID> resetEdge(long edgeId)

Description copied from interface: GraphBuilder

Resets any change for the edge with the given ID. Does nothing if no change for the given edge ID exists.

Specified by:

resetEdge in interface GraphBuilder<VID>

Specified by:

resetEdge in interface GraphChangeSet<VID>

Overrides:

resetEdge in class GraphBuilderImpl<VID>

Parameters:

edgeId - the ID of the edge which should be reset

Returns:

this graph builder

resetVertex

public GraphChangeSet<VID> resetVertex(VertexBuilder<VID> vertex)

Description copied from interface: GraphBuilder

Resets any change for the given vertex.

Specified by:

resetVertex in interface GraphBuilder<VID>

Specified by:

resetVertex in interface GraphChangeSet<VID>

Overrides:

resetVertex in class GraphBuilderImpl<VID>

Parameters:

vertex - a VertexBuilder

Returns:

this graph builder

resetVertex

public GraphChangeSet<VID> resetVertex(VID vertexId)

Description copied from interface: GraphBuilder

Resets any change for the vertex with the given ID. Does nothing if no change for the given vertex ID exists.

Specified by:

resetVertex in interface GraphBuilder<VID>

Specified by:

resetVertex in interface GraphChangeSet<VID>

Overrides:

resetVertex in class GraphBuilderImpl<VID>

Parameters:

vertexId - the ID of the vertex which should be reset

Returns:

this graph builder

setAddExistingEdgePolicy

public GraphChangeSet<VID> setAddExistingEdgePolicy(OnAddExistingElement addExistingEdgePolicy)

Description copied from interface: GraphChangeSet

Sets the policy on what to do when an edge is added that already exists

Specified by:

setAddExistingEdgePolicy in interface GraphChangeSet<VID>

Parameters:

addExistingEdgePolicy - the new policy

Returns:

this graph builder

setAddExistingVertexPolicy

public GraphChangeSet<VID> setAddExistingVertexPolicy(OnAddExistingElement addExistingVertexPolicy)

Description copied from interface: GraphChangeSet

Sets the policy on what to do when a vertex is added that already exists

Specified by:

setAddExistingVertexPolicy in interface GraphChangeSet<VID>

Parameters:

addExistingVertexPolicy - the new policy

Returns:

this graph builder

toString

public java.lang.String toString()

Overrides:

toString in class GraphBuilderImpl<VID>

updateEdge

public EdgeModifier<VID> updateEdge(long edgeId)

Description copied from interface: GraphChangeSet

Returns a EdgeModifier with which you can update edge properties and the edge label.

Specified by:

updateEdge in interface GraphChangeSet<VID>

Parameters:

edgeId - the ID of the edge that should be updated

Returns:

an VertexModifier instance

updateVertex

public VertexModifier<VID> updateVertex(VID vertexId)

Description copied from interface: GraphChangeSet

Returns a VertexModifier with which you can update vertex properties. Throws an exception if the vertex has been removed with this graph change set before.

Specified by:

updateVertex in interface GraphChangeSet<VID>

Parameters:

vertexId - the ID of the vertex that should be updated
