Element Class

Element Class

Element is a basic building block of an object model. You may refer to it as to an OOP class (type). Each entity class, either graphical or non-graphical, relates to instantiated element found within Elements collection.

Inheritance Hierarchy

SystemObject
FDF.Common.ObjectModelFeature
FDF.Common.ObjectModelElement

Namespace: FDF.Common.ObjectModel
Assembly: FDF.Common (in FDF.Common.dll) Version: 3.0.0.0

Syntax

C++

Copy

[SerializableAttribute]
public class Element : Feature, ICloneable

<SerializableAttribute>
Public Class Element
	Inherits Feature
	Implements ICloneable

[SerializableAttribute]
public ref class Element : public Feature, 
	ICloneable

[<SerializableAttribute>]
type Element =  
    class
        inherit Feature
        interface ICloneable
    end

The Element type exposes the following members.

Constructors

	Name	Description
	Element	See appropriate Feature constructor(s).
	Element(String)	See appropriate Feature constructor(s).

Attributes

Attributes represent unique properties of an Element.

For more info see description of the Attributes collection and it's enumerator, the Attribute.

ClassId

Name of underlying entity class indentificator (CLSID) utilized by host application.

In AutoCAD, for example, it represents DXF group 1001 (AppId). Since class id's are persistant, change them sparingly throughout different versions of an object model.

ClassName

Name of underlying entity class utilized by host application.

In AutoCAD, for example, class name may have one of the following values:

Class name	Description
AcDbPolyline	Lightweight Polyline entity.
AcDbPolyline2d	2D Polyline entity.
AcDbPolyline3d	3D Polyline entity.
AcDbMPolygon	Multi-polygon entity.
AcDbBlockReference	Block reference entity.

Commands

IsAbstract

Gets or sets whether this element represent a base class for building other elements.

Equals to abstract (MustInherit) class in OOP. This property is being implicitly set on schema serialization. If True, element's children should have their ParentNames set to this element's Name.

IsHidden

ParentName

Gets or sets element's parent Element name.

Equals to inherited (parent) class name in OOP. See IsAbstract for more details.

StyleName

Gets or sets element's Style name.

Type

(Overrides FeatureType.)
