Package org.apache.jackrabbit.data.core

Class TransactionContext

java.lang.Object
org.apache.jackrabbit.data.core.TransactionContext
public class TransactionContext extends Object
Represents the transaction on behalf of the component that wants to explicitly demarcate transaction boundaries. After having been prepared, schedules a task that rolls back the transaction if some time passes without any further action. This will guarantee that global objects locked by one of the resources' InternalXAResource.prepare(org.apache.jackrabbit.data.core.TransactionContext) method, are eventually unlocked.

    • commit

      public void commit() throws XAException
      Commit the transaction identified by this context. Commits changes on all resources. If some resource reports an error on commit, automatically rollback changes on all other resources. Throw exception at the end if some commit failed.

      XAException - if an error occurs

    • rollback

      public void rollback() throws XAException
      Rollback the transaction identified by this context. Rolls back changes on all resources. Throws exception at the end if errors were found.

    • getCurrentThreadId

      public static Object getCurrentThreadId()
      Returns the current thread identifier. The identifier is either the current thread instance or the global transaction identifier wrapped in a TransactionContext.XidWrapper, when running under a transaction.
      Returns:
      current thread identifier
