Package org.openspaces.core.transaction

Class DefaultTransactionProvider

java.lang.Object
org.openspaces.core.transaction.DefaultTransactionProvider
All Implemented Interfaces:
SpaceTransactionProvider, Closeable, AutoCloseable, TransactionProvider
public class DefaultTransactionProvider extends Object implements TransactionProvider
Default transaction provider works in conjunction with JiniPlatformTransactionManager and one of its derived classes. Uses Spring support for transactional resource binding (using thread local) in order to get the current transaction. If no transaction is active, will return null (which means the operation will be executed under no transaction).

Also supports for Spring JTA transaction by automatically creating and binding GigaSpaces support for XA.

As a transaction context it uses the one passed to its constructor, and not the runtime transactional context provided to getCurrentTransaction(Object, com.j_spaces.core.IJSpace)

    • getCurrentTransaction

      public Transaction getCurrentTransaction()
      Description copied from interface: SpaceTransactionProvider
      Returns the currently running transaction (usually managed externally/declarative).

      If no transaction is currently executing, null value will be returned. This usually means that the operation will be performed without a transaction.

      Specified by:
      getCurrentTransaction in interface SpaceTransactionProvider
      Returns:
      The transaction object to be used (can be null).

    • getCurrentTransaction

      public Transaction.Created getCurrentTransaction(Object transactionalContext, IJSpace space)
      Returns the current running transaction based on the constructor provided transactional context (Note that the passed transactional context is not used).

      Uses Spring support for transactional resource registration in order to fetch the current running transaction (or the JiniTransactionHolder. An example of Spring platform transaction managers that register it are ones derived form AbstractJiniTransactionManager.

      If no transaction is found bound the the transactional context (provided in the constructor), null is returned. This means that operations will execute without a transaction.

      Specified by:
      getCurrentTransaction in interface TransactionProvider
      Parameters:
      transactionalContext - Not Used. The transactional context used is the one provided in the constructor.
      space - The actual Space this operation will be performed on
      Returns:
      The current running transaction or null if no transaction is running

    • getCurrentTransactionIsolationLevel

      public int getCurrentTransactionIsolationLevel(Object transactionalContext)
      Description copied from interface: TransactionProvider
      Returns the currently running transaction isolation level (mapping to Spring TransactionDefinition.getIsolationLevel() values). A transactional context can be passed and optionally used in order to fetch the current running transaction.
      Specified by:
      getCurrentTransactionIsolationLevel in interface TransactionProvider
      Parameters:
      transactionalContext - Transactional context to (optionally) fetch the transaction by
      Returns:
      The transaction isolation level mapping to Spring TransactionDefinition.getIsolationLevel().
