Constructor Detail

### SQLTemplateAction

    public SQLTemplateAction(SQLTemplate query,
                             DbAdapter adapter,
                             EntityResolver entityResolver)

Since:
  3.0

Method Detail

### getAdapter

    public DbAdapter getAdapter()

  Returns DbAdapter associated with this execution plan object.

### performAction

    public void performAction(Connection connection,
                              OperationObserver callback)
