Class LookupTransactionManagerProvider

java.lang.Object

org.ehcache.transactions.xa.txmgr.provider.LookupTransactionManagerProvider

All Implemented Interfaces:

org.ehcache.spi.service.Service, TransactionManagerProvider

public class LookupTransactionManagerProvider
extends java.lang.Object
implements TransactionManagerProvider

A TransactionManagerProvider implementation that resolves the TransactionManagerWrapper through the lookup class provided through its LookupTransactionManagerProviderConfiguration.

The lifecycle this implementation will honour is as follows:

• On construction, instantiate the lookup class indicated by configuration
• On start the service will ask the lookup instance for a TransactionManagerWrapper which it will then cache and serve to service users.
• On stop the service will forget about the known TransactionManagerWrapper
• On subsequent start, the service will ask the lookup instance for a new TransactionManagerWrapper

Note that in this scheme, the lookup instance is not expected to cache the TransactionManagerWrapper unless it can be considered a singleton.
