IGraph Methods |
The IGraph type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | AddEdge |
Add an edge to the graph. The added edges requires a recommended identifier, a tail vertex, an head vertex, and a label.
Like adding a vertex, the provided object identifier may be ignored by the implementation.
|
| AddVertex |
Create a new vertex, add it to the graph, and return the newly created vertex.
The provided object identifier is a recommendation for the identifier to use.
It is not required that the implementation use this identifier.
|
| GetEdge |
Return the edge referenced by the provided object identifier.
If no edge is referenced by that identifier, then return null.
|
| GetEdges |
Return an iterable to all the edges in the graph.
If this is not possible for the implementation, then an NotSupportedException can be thrown.
|
| GetEdges(String, Object) |
Return an iterable to all the edges in the graph that have a particular key/value property.
If this is not possible for the implementation, then an NotSupportedException can be thrown.
The graph implementation should use indexing structures to make this efficient else a full edge-filter scan is required.
|
| GetVertex |
Return the vertex referenced by the provided object identifier.
If no vertex is referenced by that identifier, then return null.
|
| GetVertices |
Return an iterable to all the vertices in the graph.
If this is not possible for the implementation, then an NotSupportedException can be thrown.
|
| GetVertices(String, Object) |
Return an iterable to all the vertices in the graph that have a particular key/value property.
If this is not possible for the implementation, then a NotSupportedException can be thrown.
The graph implementation should use indexing structures to make this efficient else a full vertex-filter scan is required.
|
| Query |
Generate a query object that can be used to fine tune which edges/vertices are retrieved from the graph.
|
| RemoveEdge |
Remove the provided edge from the graph.
|
| RemoveVertex |
Remove the provided vertex from the graph.
Upon removing the vertex, all the edges by which the vertex is connected must be removed as well.
|
| Shutdown |
Extension Methods| Name | Description | |
|---|---|---|
 | AddEdge |
Add an edge to the graph with specified id and provided properties.
(Defined by GraphHelpers.) |
| AddVertex |
Add a vertex to the graph with specified id and provided properties.
(Defined by GraphHelpers.) |
| CopyGraph |
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.

| ReIndexElementsT |
For those graphs that do no support automatic reindexing of elements when a key is provided for indexing, this method can be used to simulate that behavior.
The elements in the graph are iterated and their properties (for the provided keys) are removed and then added.
Be sure that the key indices have been created prior to calling this method so that they can pick up the property mutations calls.
Finally, if the graph is a TransactionalGraph, then a 1000 mutation buffer is used for each commit.
