protected JEntityContext ihContext

EntityContext for non-transacted requests

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(Transaction tx)

setContext4Tx

protected void setContext4Tx(Transaction tx,
                             JEntityContext ctx)

Parameters:

tx - The Transaction

the - JEntityContext used for this tx

removeContext4Tx

protected void removeContext4Tx(Transaction tx)

passivateIH

public int passivateIH(boolean store,
                       boolean passivate)

try to passivate instances

Specified by:

passivateIH in class JEntitySwitch

Parameters:

store - not used for this policy

passivate - always true for this policy

Returns:

result of operation: (not really used here) ALL_DONE = instances passivated NOT_DONE = not all passivated

endIH

public void endIH()

Description copied from class: JEntitySwitch

Called only for CS policy, after passivateIH

Specified by:

endIH 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
