Syntax

'Declaration
<SharePointPermissionAttribute(SecurityAction.InheritanceDemand, ObjectModel := True)> _
<SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel := True)> _
Public Class MethodInstance _
    Inherits AccessControlledMetadataObject

'Usage
Dim instance As MethodInstance

[SharePointPermissionAttribute(SecurityAction.InheritanceDemand, ObjectModel = true)]
[SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel = true)]
public class MethodInstance : AccessControlledMetadataObject

Remarks

A single method can have multiple MethodInstance objects, with each MethodInstance object being a combination of the method signature and a set of default values. You can use MethodInstance objects to call the same method with different default values. MethodInstance objects are especially useful for complex Web services. For example, you may have a WebMethod that returns multiple outputs in several ref or out type Parameters. Business Data Catalog can process only a single return value at a time, so you would define such a WebMethod as a single Business Data Catalog Method, and then create multiple MethodInstances, each of which would point to a different parameter of the core method as the 'Return' parameter.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
