General Usage

This interface provides access to the association Role Tagged Values. Each connector end has a RoleTag collection that can be accessed to add, delete and access the RoleTags.

In code you create something that resembles the following code fragment for accessing a RoleTag in VB.NET (where con is a Connector Object):

 

       client = con.ClientEnd

       client.Role = "m_client"

       client.Update()

       tag = client.TaggedValues.AddNew("tag", "value")

       tag.Update()

       tag = client.TaggedValues.AddNew("tag2", "value2")

       tag.Update()

       client.TaggedValues.Refresh()

       For idx = 0 To client.TaggedValues.Count - 1

           tag = client.TaggedValues.GetAt(idx)

           Console.WriteLine(tag.Tag)

           client.TaggedValues.DeleteAt(idx, False)

       Next

       tag = Nothing
