The HostAdapterAttribute type exposes the following members.

Constructors
  NameDescription
Public method HostAdapterAttributeInitializes a new instance of the HostAdapterAttribute class.
Top
Properties
  NameDescription
Public property TypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)
Top
Methods
  NameDescription
Public method EqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Public method GetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public method GetTypeGets the Type of the current instance. (Inherited from Object.)
Public method IsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public method MatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)

Explicit Interface Implementations
  NameDescription
Explicit interface implemetation Private method _AttributeGetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetation Private method _AttributeGetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetation Private method _AttributeGetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetation Private method _AttributeInvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

Remarks

The Rebuild and Update methods, which maintain the store of information about available pipeline segments, use this attribute to identify a host-side adapter.

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.

Examples

The following example identifies a host-side adapter.

' The HostAdapterAttribute identifes this class as the host-side adapter 
' pipeline segment.
<HostAdapterAttribute()> _
Public Class CalculatorContractToViewHostSideAdapter
    Implements ICalculator
// The HostAdapterAttribute identifes this class as the host-side adapter 
// pipeline segment.
[HostAdapterAttribute()]
public class CalculatorContractToViewHostSideAdapter : ICalculator 
{
