7 6 5 4 3 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. Types of Relationships 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. Instantiation specifies that one object from one class has a method with which it creates an object from another class. 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 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. (<classname>) indicates the name of the helper class required to support this event interface in Visual Basic. 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. The objects to the left show a sample view of type inheritance. The objects below show a flat view of the objects with their full list of interfaces. The two views are equivalent, but the type inheritance view gives insight into the structural composition of the object model.

Types of Classes

An abstract class cannot create new objects; it is a specification forinstances 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 becreated as a property of another class or instantiated by objects fromanother class.

Types of Relationships

Associations represent relationships between classes. They have definedmultiplicities at both ends.

Type inheritance defines specialized classes of objects that shareproperties and methods with the superclass and have additionalproperties and methods. Note that interfaces in superclasses are notduplicated in subclasses.

Instantiation specifies that one object from one class has a method withwhich it creates an object from another class.

Composition is a relationship in which objects from the "whole" classcontrol the lifetime of objects from the "part" class.

An N-ary association specifies that more than two classes areassociated. A diamond is placed at the intersection of the associationbranches.

A multiplicity is a constraint on the number of objects that can beassociated with another object. Association and composition relationshipshave 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

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.(<classname>) indicates the name of the helper class required to support thisevent interface in Visual Basic.

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

The objects to the left show a sample view of type inheritance. The objects belowshow a flat view of the objects with their full list of interfaces. The two views areequivalent, but the type inheritance view gives insight into the structuralcomposition of the object model.

Spatial reference

A prime meridian objectspecifies the line of zerolongitude for the coordinates ina geographic coordinate system.

The spheroid object models theapproximate shape of the earth's surface

The angular unit specifies themeasurement units used in ageographic coordinate system

A projected coordinate systemobject includes a geographic

coordinate system, aprojection, a set of projection

parameters, and a linear unit

A projection object specifies the mathematicaltransformation to convert between geographic

and planar coordinates

The parameter can be used todefine and modify the values forspecific properties for a projectedcoordinate system

The linear unit specifies themeasurement units used in aprojected coordinate system.

The unknown coordinate system is used when thecoordinate system is not known or unavailable

The spatial reference is the base for three types of coordinatesystems: projected, geogaphic, and unknown

The geographic coordinatesystem defines a coordinate

system that describes thepositions of features on the

earth using latitude andlongitude values

A datum represents areference system for latitude-

longitude coordinates and isdefined by a spheroid and thespheroid's position relative to

the center of the earth

Types of Classes

An abstract class cannot create new objects; it is a specification forinstances 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 becreated as a property of another class or instantiated by objects fromanother class.

Types of Relationships

Associations represent relationships between classes. They have definedmultiplicities at both ends.

Type inheritance defines specialized classes of objects that shareproperties and methods with the superclass and have additionalproperties and methods. Note that interfaces in superclasses are notduplicated in subclasses.

Instantiation specifies that one object from one class has a method withwhich it creates an object from another class.

Composition is a relationship in which objects from the "whole" classcontrol the lifetime of objects from the "part" class.

An N-ary association specifies that more than two classes areassociated. A diamond is placed at the intersection of the associationbranches.

A multiplicity is a constraint on the number of objects that can beassociated with another object. Association and composition relationshipshave 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

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.(<classname>) indicates the name of the helper class required to support thisevent interface in Visual Basic.

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

The objects to the left show a sample view of type inheritance. The objects belowshow a flat view of the objects with their full list of interfaces. The two views areequivalent, but the type inheritance view gives insight into the structuralcomposition of the object model.

The conflicts window isthe ArcMap ConflictResolution dialog box

The snapping command is the ArcMap editor'ssnapping window where snap agent properties are set

An edit selection cache stores theselection for fast hit testing

The sketch tool is the editor's maintool for creating an edit sketch

The feature inspector is thecontrol inside the attributes dialogbox that enables attribute editing

The digitizer extension allowsthe ArcMap editor to work witha digitizing board and puck

The topological editor extensionenables the ArcMap editor toperform shared geometry editing

Editor extensions are additionalobjects that aid editing

The Editor gives ArcMapfeature editing capabilities

Edit tasks perform aspecific operation

using the edit sketch

Snap agents aid inpositioning geometriesby snapping them toother geometries

Types of Classes

An abstract class cannot create new objects; it is a specification forinstances 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 becreated as a property of another class or instantiated by objects fromanother class.

Types of Relationships

Associations represent relationships between classes. They have definedmultiplicities at both ends.

Type inheritance defines specialized classes of objects that shareproperties and methods with the superclass and have additionalproperties and methods. Note that interfaces in superclasses are notduplicated in subclasses.

Instantiation specifies that one object from one class has a method withwhich it creates an object from another class.

Composition is a relationship in which objects from the "whole" classcontrol the lifetime of objects from the "part" class.

An N-ary association specifies that more than two classes areassociated. A diamond is placed at the intersection of the associationbranches.

A multiplicity is a constraint on the number of objects that can beassociated with another object. Association and composition relationshipshave 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

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.(<classname>) indicates the name of the helper class required to support thisevent interface in Visual Basic.

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

The objects to the left show a sample view of type inheritance. The objects belowshow a flat view of the objects with their full list of interfaces. The two views areequivalent, but the type inheritance view gives insight into the structuralcomposition of the object model.
