Examples of org.eclipse.ecf.core.identity.ID

org.eclipse.ecf.core.identity.ID
Contract for ECF identity
ECF IDs are immutable once constructed, and unique within the containing {@link Namespace}.
ID instances are created via the Namespace.createInstance(...) method. This method is called by the IDFactory.createID(...) methods for the given Namespace. So, for example, to create an ID instance with the name "slewis":
```
 ID id = IDFactory.getDefault().createID(namespace, "slewis"); 
```
@see Namespace
