RoleTag Class
The RoleTag interface provides access to an Association's Role Tagged Values. Each connector end has a RoleTag collection that can be accessed to add, delete and access the RoleTags.
You might use this in creating code that resembles this 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
