IMessagePrefixProvider (Eclipse Platform API Specification)

```
public interface IMessagePrefixProvider
```
This interface computes the prefix of a message that is created in the context of a control. Since messages are rolled up to the header in the message manager, it is important to create a prefix to indicate the context of a message in the form. Typically the prefix is computed by looking at the label that preceeds the control, if present. Alternative providers may include other text to further specify the location of the message.
