Interface ITypeRepository

public interface ITypeRepository
The external representation of the repository of Java types, which gives access to the application's classes.

Important: IType.UNRESOLVABLE_TYPE has to be handled by the implementer, which has to be done in getType(String). It indicates the type is unresolvable or simply unknown.

Provisional API: This interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.
