Method Detail

vertexAdded

void vertexAdded(Vertex vertex)

Raised when a new Vertex is added.

Parameters:

vertex - the vertex that was added

vertexPropertyChanged

void vertexPropertyChanged(Vertex vertex,
                         String key,
                         Object oldValue,
                         Object setValue)

Raised after the property of a vertex changed.

Parameters:

vertex - the vertex that changed

key - the key of the property that changed

setValue - the new value of the property

vertexPropertyRemoved

void vertexPropertyRemoved(Vertex vertex,
                         String key,
                         Object removedValue)

Raised after a vertex property was removed.

Parameters:

vertex - the vertex that changed

key - the key that was removed

removedValue - the value of the property that was removed

vertexRemoved

void vertexRemoved(Vertex vertex,
                 Map<String,Object> props)

Raised after a vertex was removed from the graph.

Parameters:

vertex - the vertex that was removed

props - the properties of the removed vertex

edgeAdded

void edgeAdded(Edge edge)

Raised after a new edge is added.

Parameters:

edge - the edge that was added

edgePropertyChanged

void edgePropertyChanged(Edge edge,
                       String key,
                       Object oldValue,
                       Object setValue)

Raised after the property of a edge changed.

Parameters:

edge - the edge that changed

key - the key of the property that changed

setValue - the new value of the property

edgePropertyRemoved

void edgePropertyRemoved(Edge edge,
                       String key,
                       Object removedValue)

Raised after an edge property was removed.

Parameters:

edge - the edge that changed
