getResultCount
public int getResultCount()(Code)



getResultOID
public OID getResultOID()(Code)
Get the OID for the current result. This may only be called once per result and must be called before getResultState.



getResultState
public State getResultState(boolean forUpdate, StateContainer container)(Code)
Get the State for the current result. This may only be called once per result and may only be called if getResultOID has been called.
