AddInSegmentType Enumeration

 

Specifies the type of a pipeline segment.

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

public enum AddInSegmentType

Member nameDescription
AddIn

Specifies an add-in segment.

AddInSideAdapter

Specifies an add-in-side adapter segment.

AddInView

Specifies an add-in view segment.

Contract

Specifies a contract segment.

HostSideAdapter

Specifies a host-side adapter segment.

HostViewOfAddIn

Specifies the host view of the add-in segment.

In this context, the type of a pipeline segment identifies the category of pipeline segment: add-in, add-in-side adapter, add-in view, contract, host-side adapter, or the host view of the add-in. If a pipeline segment's class has a QualificationDataAttribute attribute, you can obtain the data specified in the attribute with the QualificationData property of an AddInToken object.

The following example uses the AddInSegmentType enumeration to evaluate an add-in's qualification data.

// Use qualification data to control 
// how an add-in should be activated.

if (selectedToken.QualificationData[AddInSegmentType.AddIn]["Isolation"].Equals("NewProcess"))
{
	// Create an external process.
	AddInProcess external = new AddInProcess();

    // Activate an add-in in the new process
    // with the full trust security level.
    Calculator CalcAddIn5 =
		selectedToken.Activate<Calculator>(external,
		AddInSecurityLevel.FullTrust);
	Console.WriteLine("Add-in activated per qualification data.");
}
else
	Console.WriteLine("This add-in is not designated to be activated in a new process.");
