  • Method Details

    • getUserObject

      Object getUserObject(StatementUserObjectRuntimeContext env)
      Returns the user object to assign to a newly-deployed statement.

      Implementations would typically interrogate the context object EPL expression or module and module item information and determine the right user object to assign.

      When using HA the returned object must implement the Serializable interface.

      Parameters:
      env - the statement's deployment context
      Returns:
      user object or null if none needs to be assigned
