Arc Gis object Model

Diagram key

ArcObjects is the development platform for ArcGIS Desktop, a suite of GIS software systems: ArcInfo, ArcEditor, and ArcView. These systems serve GIS professionals with a spectrum of geographic data management, spatial editing, and cartographic visualization functionality.

ESRI® ArcObjects™ is the development platform for the ArcGIS™ family of applications such as ArcMap™, ArcCatalog™, and ArcScene™. The ArcObjects software components expose the full range of functionality available in ArcInfo™, ArcEditor™, and ArcView™ to software developers.

Type inheritance defines specialized classes of objects that share properties and methods with the superclass and have additional properties and methods. Note that interfaces in superclasses are not duplicated in subclasses. Instantiation specifies that one object from one class has a method with which it creates an object from another class.

Geometry coclass

Type inheritance defines specialized classes of objects that share properties and methods with the superclass and have additional properties and methods. Note that interfaces in superclasses are not duplicated in subclasses.

Special Interfaces (Optional) represents interfaces that are inherited by some subclasses but not all. The subclasses list the optional interfaces they implement. (Instance) represents interfaces that are only on specific instances of the class. () indicates the name of the helper class required to support this event interface in Visual Basic.

Types of Classes An abstract class cannot create new objects; it is a specification for instances of subclasses (through type inheritance.) A coclass can directly create objects by declaring a new object. A class cannot directly create objects, but objects of this class can be created as a property of another class or instantiated by objects from another class.

Geocoding object model

Associations represent relationships between classes. They have defined multiplicities at both ends. Type inheritance defines specialized classes of objects that share properties and methods with the superclass and have additional properties and methods. Note that interfaces in superclasses are not duplicated in subclasses.

Composition

Reclassifies rasters using tables to define categories

Type inheritance This diagram illustrates the implicit type inheritance model in the ArcGIS 8.1 component objects. Software interfaces are not duplicated in the child classes.

A class cannot directly create objects, but objects of this class can be created as a property of another class or instantiated by objects from another class. Types of Relationships

Association

You will find updates to ArcObjects developer resources at www.esri.com/arcobjectsonline.

Types of Classes An abstract class cannot create new objects; it is a specification for instances of subclasses (through type inheritance.) A coclass can directly create objects by declaring a new object.

Composition is a relationship in which objects from the "whole" class control the lifetime of objects from the "part" class. An N-ary association specifies that more than two classes are associated. A diamond is placed at the intersection of the association branches. A multiplicity is a constraint on the number of objects that can be associated with another object. Association and composition relationships have multiplicities on both sides. This is the notation for multiplicities: 1 - One and only one (if none shown, "1" is implied) 0..1 - Zero or one M..N - From M to N (positive integers) * or 0..* - From zero to any positive integer 1..* - From one to any positive integer
