Method Detail

• setAutoEndTransactions

  public static void setAutoEndTransactions(boolean autoEnd)

  Sets automatic transaction end support. When this is on, transaction support is ended when you commit or rollback a transaction; any further database operations in this HTTP request will be auto-committed. When this is off, transaction support persists beyond a commit or rollback boundary, so further database operations in this HTTP request will be part of a new transaction and must be committed manually. By default, automatic transaction end support is off. This means that your code is responsible for calling endTransaction().

  Parameters:

  autoEnd - If true, switches on auto-end support

• startTransaction

  public static boolean startTransaction(RPCManager rpc)
                                  throws java.lang.Exception

  Starts a new database transaction. Note that when you use transactional support, your code is responsible for calling endTransaction() - if you neglect to do so, you will cause connection leaks. It is possible to have the transaction manager end transactions automatically for you after a commit or rollback - this facility is controlled by the static SQLTransaction.setAutoEndTransactions() method.

  Throws:

  java.lang.Exception

• getConnection

  public static java.sql.Connection getConnection(RPCManager rpc)
                                           throws java.lang.Exception

  Returns the connection participating in the transaction. This will be null until startTransaction() is called.

  Throws:

  java.lang.Exception - if there is a configuration error with one of the underlying datasources

• rollbackTransaction

  public static void rollbackTransaction(RPCManager rpc)
                                  throws java.lang.Exception

  Rollback the current transaction

  Throws:

  java.lang.Exception - if problems were found rolling back the transaction

• commitTransaction

  public static void commitTransaction(RPCManager rpc)
                                throws java.lang.Exception

  Commit the current transaction

  Throws:

  java.lang.Exception - if problems were found committing the transaction

• endTransaction

  public static void endTransaction(RPCManager rpc)
                             throws java.lang.Exception

  End the current transaction. "Ending" a transaction simply means surrendering the database connection we are using to represent the transaction back to the pool. Any further database operations in this HTTP request will take place on an auto-commit basis, unless you issue another startTransaction call. Note that startTransaction() calls MUST be paired with endTransaction() calls, unless you have set the transaction manager into auto-end mode (see SQLTransaction.setAutoEndTransactions()).

  Throws:

  java.lang.Exception - if problems were found ending the transaction
