Interface GraphManager

All Superinterfaces:

GraphChangeHandler

All Known Implementing Classes:

GraphMap, NoSyncObjectStore, ObjectStore

public interface GraphManager
extends GraphChangeHandler

Represents a generic "managed" graph with nodes mapped by their ids. Inherited GraphChangeHandler methods are intended as callbacks for graph node objects to notify graph of their changes.

Since:

1.2

Method Summary

Modifier and Type	Method	Description
Object	getNode(Object nodeId)	Returns a graph node given an id.
Collection<Object>	registeredNodes()	Returns all graph nodes registered with GraphManager.
void	registerNode(Object nodeId, Object nodeObject)	"Registers" a graph node, usually storing the node in some internal map using its id as a key.
Object	unregisterNode(Object nodeId)	"Unregisters" a graph node, forgetting any information associated with nodeId.

Modifier and Type	Method	Description
default void	arcCreated(Object nodeId, Object targetNodeId, ArcId arcId)	Notifies implementing object that a new arc was created between two nodes.
default void	arcDeleted(Object nodeId, Object targetNodeId, ArcId arcId)	Notifies implementing object that an arc between two nodes was deleted.
default void	nodeCreated(Object nodeId)	Notifies implementing object that a new node was created in the graph.
default void	nodeIdChanged(Object nodeId, Object newId)	Notifies implementing object that a node was assigned a new id.
default void	nodePropertyChanged(Object nodeId, String property, Object oldValue, Object newValue)	Notifies implementing object that a node's property was modified.
default void	nodeRemoved(Object nodeId)	Notifies implementing object that a node was removed from the graph.
