Interface NameLookup

All Known Subinterfaces:

UIFormAdaptorCallback, UIFormOwner

public interface NameLookup

Provides general object resolution capabilities. A NameLookup is needed to transform a String object reference into an actual instance. While this can be done using a query, the resulting reference resolution code would be unnecessarily complex. This is similar to IDLookup but used for String references.
