Syntax
public abstract class IAttributeUsage : EngineObjectRemarks
An implementation of the IAttributeUsage interface is passed as an argument to the ICustomSymbol.GetAttributeUsage method. The custom symbol implementation can use it to tell Carmenta Engine which Feature attributes are used to generate the custom symbol. This information is used by Carmenta Engine to cache custom symbols correctly.
// Tell Carmenta Engine that the attribute AnotherAttribute is used
// when the BaseAttribute exists
attributeUsage.AddItem(
"AnotherAttribute",
new Condition("BaseAttribute != null"));
