getAllNodes in interface GraphDatabaseServicepublic Iterable<RelationshipType> getRelationshipTypes()
GraphDatabaseServicenode.createRelationshipTo(...). Note that this method is guaranteed to
return all known relationship types, but it does not guarantee that it
won't return more than that (e.g. it can return "historic"
relationship types that no longer have any relationships in the node
space).
getRelationshipTypes in interface GraphDatabaseServicepublic KernelEventHandler registerKernelEventHandler(KernelEventHandler handler)
GraphDatabaseServicehandler as a handler for kernel events which
are generated from different places in the lifecycle of the kernel.
To guarantee proper behaviour the handler should be registered right
after the graph database has been started. If the specified handler
instance has already been registered this method will do nothing.
registerKernelEventHandler in interface GraphDatabaseServicehandler - the handler to receive events about different states
in the kernel lifecycle.
public <T> TransactionEventHandler<T> registerTransactionEventHandler(TransactionEventHandler<T> handler)
GraphDatabaseServicehandler as a handler for transaction events which
are generated from different places in the lifecycle of each
transaction. To guarantee that the handler gets all events properly
it shouldn't be registered when the application is running (i.e. in the
middle of one or more transactions). If the specified handler instance
has already been registered this method will do nothing.
registerTransactionEventHandler in interface GraphDatabaseServiceT - the type of state object used in the handler, see more
documentation about it at TransactionEventHandler.handler - the handler to receive events about different states
in transaction lifecycles.
public KernelEventHandler unregisterKernelEventHandler(KernelEventHandler handler)
GraphDatabaseServicehandler from the list of kernel event handlers.
If handler hasn't been registered with
GraphDatabaseService.registerKernelEventHandler(KernelEventHandler) prior to calling
this method an IllegalStateException will be thrown.
After a successful call to this method the handler will no
longer receive any kernel events.
unregisterKernelEventHandler in interface GraphDatabaseServicehandler - the handler to receive events about different states
in the kernel lifecycle.
public <T> TransactionEventHandler<T> unregisterTransactionEventHandler(TransactionEventHandler<T> handler)
GraphDatabaseServicehandler from the list of transaction event handlers.
If handler hasn't been registered with
GraphDatabaseService.registerTransactionEventHandler(TransactionEventHandler) prior
to calling this method an IllegalStateException will be thrown.
After a successful call to this method the handler will no
longer receive any transaction events.

documentation about it at TransactionEventHandler.handler - the handler to receive events about different states
in transaction lifecycles.
