Class Session

java.lang.Object
org.postgresql.pljava.internal.Session
All Implemented Interfaces:
Session
public class Session extends Object implements Session
An instance of this interface reflects the current session. The attribute store is deprecated. It had interesting transactional behavior until PL/Java 1.2.0, but since then it has behaved as any (non-null-allowing) Map. Anyone needing any sort of attribute store with transactional behavior will need to implement one and use a TransactionListener to keep it sync'd.

  • Method Details

    • provider

      public static Session provider()

    • addTransactionListener

      public void addTransactionListener(TransactionListener listener)
      Adds the specified listener to the list of listeners that will receive transactional events.
      Specified by:
      addTransactionListener in interface Session

    • addSavepointListener

      public void addSavepointListener(SavepointListener listener)
      Adds the specified listener to the list of listeners that will receive savepoint events.
      Specified by:
      addSavepointListener in interface Session

    • getAttribute

      @Deprecated(since="1.5.3", forRemoval=true) public Object getAttribute(String attributeName)
      Deprecated, for removal: This API element is subject to removal in a future version.
      Session's attribute store once had a special, and possibly useful, transactional behavior, but since PL/Java 1.2.0 it has lacked that, and offers nothing you don't get with an ordinary Map (that forbids nulls). If some kind of store with transactional behavior is needed, it should be implemented in straight Java and kept in sync by using a TransactionListener.
      Get an attribute from the session's attribute store.

      getAttribute in interface Session
