Detailed Description

Notifying behavior.

Library: ilvproto

Lets you make an attribute 'Notifying' (also called output value). This means that other attributes can be notified of changes to the first attribute. The value of this first attribute is propagated to the others whenever the value is changed.

IlvLoopbackAccessor.

Constructor & Destructor Documentation

IlvOutputAccessor::IlvOutputAccessor ( const char *  name,
const IlvValueTypeClass type 
)

Creates an IlvOutputAccessor, making the attribute name a notifying attribute.

Parameters
nameName of the attribute
typeType needed for initialization purposes, but not used otherwise.

Member Function Documentation

virtual IlBoolean IlvOutputAccessor::isOutputValue ( const IlSymbol name) const
virtual

Queries if the accessor is an output accessor.

Returns
IlTrue if the accessor is an output accessor, and IlFalse otherwise.

Reimplemented from IlvUserAccessor.
