Interface TinkerGraph.IdManager<T>

Type Parameters:

T - the id type

All Known Implementing Classes:

TinkerGraph.DefaultIdManager

Enclosing class:

TinkerGraph

public static interface TinkerGraph.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 TinkerGraph.DefaultIdManager.LONG implementation will allow g.vertices(1l, 2l) and g.vertices(1, 2) to both return values.

Method Summary

Modifier and Type	Method and Description
boolean	allow(Object id) Determine if an identifier is allowed by this manager given its type.
T	convert(Object id) Convert an identifier to the type required by the manager.
T	getNextId(TinkerGraph graph) Generate an identifier which should be unique to the TinkerGraph instance.
