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
