Package org.apache.tinkerpop.gremlin.tinkergraph.structure

Interface AbstractTinkerGraph.IdManager<T>

Type Parameters:
T - the id type
All Known Implementing Classes:
AbstractTinkerGraph.DefaultIdManager
Enclosing class:
AbstractTinkerGraph
public static interface AbstractTinkerGraph.IdManager<T>
TinkerGraph will use an implementation of this interface to generate identifiers when a user does not supply them and to handle identifier conversions when querying to provide better flexibility with respect to handling different data types that mean the same thing. For example, the AbstractTinkerGraph.DefaultIdManager.LONG implementation will allow g.vertices(1l, 2l) and g.vertices(1, 2) to both return values.
