List of registerTransactionEventHandler() Examples

Examples of registerTransactionEventHandler()

org.neo4j.graphdb.GraphDatabaseService.registerTransactionEventHandler()
Registers {@code handler} as a handler for transaction events whichare 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. @param < T> the type of state object used in the handler, see moredocumentation about it at {@link TransactionEventHandler}. @param handler the handler to receive events about different statesin transaction lifecycles. @return the handler passed in as the argument.
