Constructor Detail

JEntitySwitchCRC

public JEntitySwitchCRC()
empty constructor. Object is initialized via init() because it is implemented differently according to jorm mappers.

Method Detail

initpolicy

protected void initpolicy(JEntityFactory bf)
Specified by:
initpolicy in class JEntitySwitch

getContext4Tx

protected JEntityContext getContext4Tx(javax.transaction.Transaction tx)

setContext4Tx

protected void setContext4Tx(javax.transaction.Transaction tx,
                             JEntityContext ctx)
Parameters:
tx - The Transaction

removeContext4Tx

protected void removeContext4Tx(javax.transaction.Transaction tx)

waitmyturn

public void waitmyturn(javax.transaction.Transaction tx)

passivateIH

public boolean passivateIH(boolean passivation)
try to passivate IH (called from swapper)

Specified by:
passivateIH in class JEntitySwitch
Parameters:
passivation - false if only store bean state.
Returns:
false if instance still in memory (busy for example)

endIH

public void endIH()
Specified by:
endIH in class JEntitySwitch

notifyWriting

public void notifyWriting(javax.transaction.Transaction tx,
                          JEntityContext bctx)
Specified by:
notifyWriting in class JEntitySwitch

getState

public int getState()
Specified by:
getState in class JEntitySwitch
Returns:
State of this instance. State values are 0=in-tx, 1=out-tx, 2=idle, 3=passive, 4=removed. we don't synchronize this method to avoid jadmin blocks
