Parameters:

usageLevel - usage level to match.

Returns:

The handle of the Criteria object or null if no matching object was found.

get

public Criteria get(int usageValue)

Returns Criteria object associated with the given numeric usage-level value.

Parameters:

usageValue - usage value to match.

Returns:

The handle of the Criteria object or null if no matching object was found.

getUsageLevelTag

public UsageLevelTag getUsageLevelTag(int usageValue)

Returns the UsageLevelTag object associated with the given numeric usage-level value (if it is used in this object's table).

Parameters:

usageValue - usage value to match.

Returns:

The handle of the UsageLevelTag object or null if no matching object was found.

useValToStatus

public StatusLevelTag useValToStatus(UsageLevelTag usageLevel,
