Database.Bolt.Extras.Query

Synopsis

Documentation

The combinations of Getters to load graph from the database.

The graph of Nodes and URelationships which we got from the database using GraphGetRequest.

The graph of Nodes with specified uploading type and URelationships.

The graph of BoltIds corresponding to the nodes and relationships which we get after putting GraphPutRequest.

Helper to find Nodes.

For the given GraphGetRequest find all graphs, which match it. This function creates single cypher query and performs it.

Creates graph using given GraphPutRequest. If there were multiple choices while merging given _vertices, the first match is used for connection.
