C# 클래스 Spring.Transaction.Support.TransactionSynchronizationManager

Internal class that manages resources and transaction synchronizations per thread.

Supports one resource per key without overwriting, i.e. a resource needs to be removed before a new one can be set for the same key. Supports a list of transaction synchronizations if synchronization is active.

Resource management code should check for thread-bound resources via GetResource(). It is normally not supposed to bind resources to threads, as this is the responsiblity of transaction managers. A further option is to lazily bind on first use if transaction synchronization is active, for performing transactions that span an arbitrary number of resources.

Transaction synchronization must be activated and deactivated by a transaction manager via InitSynchronization and ClearSynchronization. This is automatically supported by Spring.Transaction.Support.AbstractPlatformTransactionManager.

Resource management code should only register synchronizations when this manager is active, and perform resource cleanup immediately else. If transaction synchronization isn't active, there is either no current transaction, or the transaction manager doesn't support synchronizations.

Note that this class uses following naming convention for the named 'data slots' for storage of thread local data, 'Spring.Transaction:Name' where Name is either

BindResource ( Object key, Object value ) : void	Bind the given resource for teh given key to the current thread
Clear ( ) : void	Clears the entire transaction synchronization state for the current thread, registered synchronizations as well as the various transaction characteristics.
ClearSynchronization ( ) : void	Deactivate transaction synchronization for the current thread. Called by transaction manager on transaction cleanup.
GetResource ( Object key ) : object	Retrieve a resource for the given key that is bound to the current thread.
HasResource ( Object key ) : bool	Check if there is a resource for the given key bound to the current thread.
InitSynchronization ( ) : void	Activate transaction synchronization for the current thread. Called by transaction manager at the beginning of a transaction.
RegisterSynchronization ( ITransactionSynchronization synchronization ) : void	Register a new transaction synchronization for the current thread. Typically called by resource management code.
