AddInBaseAttribute Class

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

System.Object
  System.Attribute
    System.AddIn.Pipeline.AddInBaseAttribute

Namespace:  System.AddIn.Pipeline
Assembly:  System.AddIn (in System.AddIn.dll)

[AttributeUsageAttribute(AttributeTargets.Class|AttributeTargets.Interface)]
public sealed class AddInBaseAttribute : Attribute

The AddInBaseAttribute type exposes the following members.

  NameDescription
Public methodAddInBaseAttributeInitializes a new instance of the AddInBaseAttribute class.
Top

  NameDescription
Public propertyActivatableAsGets or sets one or more add-in base types that a single add-in-side adapter can use to construct the pipeline.
Public propertyTypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)
Top

  NameDescription
Public methodEqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public methodMatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

  NameDescription
Explicit interface implemetationPrivate method_Attribute.GetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.InvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

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.

The following example identifies the add-in base class for an add-in view pipeline segment.

// The AddInBaseAttribute identifes this interface as the basis for 
// the add-in view pipeline segment.
