Identifies an object as an add-in view segment of the pipeline.

Examples
The following example identifies the add-in base class for an add-in view pipeline segment.
// The AddInBaseAttribute identifies this interface as the basis for
// the add-in view pipeline segment.
[AddInBase()]
public interface ICalculator
{
' The AddInBaseAttribute identifies this interface as the basis for the
' add-in view pipeline segment.
<AddInBaseAttribute()> _
Public Interface ICalculator
Remarks
The Rebuild and Update methods, which maintain the store of information about available pipeline segments, use this attribute to identify an add-in view.
To construct the pipeline, the type in the add-in view that the add-in inherits from is identified by the AddInBaseAttribute attribute and is called the add-in base.
This attribute should be used only on types that activate the segments of the pipeline. Types that represent objects passed between the host and the add-in do not need this attribute.
Constructors
AddInBaseAttribute() |
Initializes a new instance of the AddInBaseAttribute class. |
Properties
ActivatableAs |
Gets or sets one or more add-in base types that a single add-in-side adapter can use to construct the pipeline. |
TypeId |
When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute) |
Methods
Equals(Object) |
Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute) |
GetHashCode() |
Returns the hash code for this instance. (Inherited from Attribute) |
GetType() |
Gets the Type of the current instance. (Inherited from Object) |
IsDefaultAttribute() |
When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute) |
Match(Object) |
When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute) |
MemberwiseClone() |
Creates a shallow copy of the current Object. (Inherited from Object) |
ToString() |
Returns a string that represents the current object. (Inherited from Object) |
Explicit Interface Implementations
_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr) |
Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute) |
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr) |
Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute) |
_Attribute.GetTypeInfoCount(UInt32) |
Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute) |
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr) |
Provides access to properties and methods exposed by an object. (Inherited from Attribute) |
