Detailed Description

Modifies an attribute with respect to numerical bounds.

Library: ilvproto
Specialized accessor that handles values with a minimum and a maximum boundary. This accessor allows you to modify another attribute when the value goes beyond the minimum and the maximum values specified.

Constructor & Destructor Documentation

§ IlvMinMaxAccessor()

IlvMinMaxAccessor::IlvMinMaxAccessor ( const char *  name,
const IlvValueTypeClass type,
IlvDisplay display,
const char *  minimumValue,
const char *  maximumValue,
const char *  exceptValue,
const char *  assignedAttribute,
const char *  valueIfBelow,
const char *  valueIfInBetween,
const char *  valueIfAbove 
)

Creates a new IlvMinMaxAccessor.

minimumValue, maximumValue, exceptValue, valueIfBelow, valueIfInBetween, and valueIfAbove can contain a constant value, the name of another accessor, or an arithmetic expression that can contain accessor names and/or constants (see IlvUserAccessor::getValue()).

Parameters
nameName of the accessor.
typeType of the accessor. It will most likely be a numeric type, such as IlvValueIntType or IlvValueFloatType.
displayDisplay used to initialize value types.
minimumValueMinimum bound used for the conditional assignment.
maximumValueMaximum bound used for the conditional assignment.
exceptValueBoolean value that is tested before performing the assignment. If it returns IlTrue, the conditional assignment is not performed.
assignedAttributeAttribute changed when the test is evaluated.
valueIfBelowValue assigned to assignedAttribute if the current value is below minimumValue.
valueIfInBetweenValue assigned to assignedAttribute if the current value is between maximumValue and minimumValue.
valueIfAboveValue assigned to assignedAttribute if the current value is above maximumValue.
