Method Detail

addVertex

public static Vertex addVertex(Graph graph,
               Object id,
               Object... properties)

Add a vertex to the graph with specified id and provided properties.

Parameters:

graph - the graph to create a vertex in

id - the id of the vertex to create

properties - the properties of the vertex to add (must be String,Object,String,Object,...)

Returns:

the vertex created in the graph with the provided properties set

addEdge

public static Edge addEdge(Graph graph,
           Object id,
           Vertex outVertex,
           Vertex inVertex,
           String label,
           Object... properties)

Add an edge to the graph with specified id and provided properties.

Parameters:

graph - the graph to create the edge in

id - the id of the edge to create

outVertex - the outgoing/tail vertex of the edge

inVertex - the incoming/head vertex of the edge

label - the label of the edge

properties - the properties of the edge to add (must be String,Object,String,Object,...)

Returns:

the edge created in the graph with the provided properties set

copyGraph

public static void copyGraph(Graph from,
             Graph to)

Copy the vertex/edges of one graph over to another graph. The id of the elements in the from graph are attempted to be used in the to graph. This method only works for graphs where the user can control the element ids.

Parameters:

from - the graph to copy from

to - the graph to copy to
