Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
When To Use
The IAnnotationExpressionEngine interface is implemented by the script engine coclasses. This is a low level interface maintaining information about the labeling expression.
The AppendCode property provides the language specific characters needed to append two strings.
The CreateFunction method creates a simple expression properly formatted for the parser language.
The SetCode and SetExpression are used to set the label expression into the parser. SetCode is used for adavanced expressions while SetExpression is used for simple expressions.
