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)
