ITypeRepository (EclipseLink 2.7.15, API Reference)

```
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.

    Returns:
    
    The external form for the given Enum type or null if none exists
  - getType
```
IType getType(java.lang.Class<?> type)
```

    Parameters:
    
    type - The Java type to wrap with an external form
    
    Returns:
    
    The external form of the given type
  - getType
```
IType getType(java.lang.String typeName)
```
    Retrieves the external class for the given fully qualified class name.
    
    Parameters:
    
    typeName - The fully qualified class name of the class to retrieve
    
    Returns:
    
    The external form of the class to retrieve
  - getTypeHelper
```
