replacingStateManager(pc, sm) - JDO StateManager's method

Method
javax.jdo.spi.StateManager
StateManager replacingStateManager(
  PersistenceCapable pc,
  StateManager sm
)

Replace the current value of jdoStateManager.

Parameters:
pc - the calling PersistenceCapable instance
sm - the proposed new value for the jdoStateManager
Returns:
the new value for the jdoStateManager
Since:
JDO 1.0
