setPreUpdateState

public final void setPreUpdateState()

Description copied from interface: UpdatableDBObject

This method is called by the J/R bridging engine after an object has been setup from some tuple retrieved from the database. The method must cause the object to save a copy (/clone) of all the fields that are pertinent to the database. This copy will be retrieved by the J/R bridging engine using the getPreUpdateState() method call, and will subsequently be used by the J/R bridging engine to determine which fields have changed value, and thus to determine which attributes need to be updated in the database.

setStorageSpaceID

public final void setStorageSpaceID(int storageSpaceID)

Sets the ID

Parameters:

storageSpaceID - The ID to set.

setStorageSpaceID

@AttributeDef(attributeName="STORAGESPACEID",
              requiresEscaping=false,
              typeName="INT")
public final void setStorageSpaceID(ValueBuffer storageSpaceID)

Sets the ID

Parameters:

storageSpaceID - The ID to set.
