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	(	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, exceptIf, 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:

	name	Name of the accessor.
	type	Type of the accessor. It will most likely be a numeric type, such as IlvValueIntType or IlvValueFloatType.
	display	Display used to initialize value types.
	minimumValue	Minimum bound used for the conditional assignment.
	maximumValue	Maximum bound used for the conditional assignment.
	exceptIf	Boolean value that is tested before performing the assignment. If it returns IlTrue, the conditional assignment is not performed.
	assignedAttribute	Attribute changed when the test is evaluated.
	valueIfBelow	Value assigned to assignedAttribute if the current value is below minimumValue.
	valueIfInBetween	Value assigned to assignedAttribute if the current value is between maximumValue and minimumValue.
	valueIfAbove	Value assigned to assignedAttribute if the current value is above maximumValue.
