Collection of symbols and id pairs.
| Interfaces | Description |
|---|---|
| IClone (esriSystem) | Provides access to members that control cloning of objects. |
| IPersist | Defines the single method GetClassID, which is designed to supply the CLSID of an object that can be stored persistently in the system. IPersist is the base interface for three other interfaces: IPersistStorage, IPersistStream, and IPersistFile. |
| IPersistStream (esriSystem) | |
| ISymbolCollection | Provides access to members that control a collection of symbols and id pairs. |
| ISymbolCollection2 | Provides access to members that control a collection of symbols and id pairs. |
A symbol collection is a collection of SymbolIdentifiers that each have a name, a symbol, and a unique ID. This is a generic collection that can store any symbol type, however, this object is primarily used in the AnnotationFeatureClassExtension as an efficient way to store TextSymbols for AnnotationFeatures. Rather than storing the TextSymbol of an AnnotationFeature with each row of the FeatureClass, AnnotationFeatures that have the same symbol can efficiently reference the same symbol in the SymbolCollection. The linkage between the TextElement of the AnnotationFeature and the symbol in the SymbolCollection is established using the interface ISymbolCollectionElement on the TextElement. ISymbolCollectionElement also provides additional access to properties that can be individually overridden for each TextElement. See ISymbolCollectionElement for more details.
