public @interface TypeRole

A type role indicates a method element in a repository that plays a role in query execution and should not be factored into query calculation but instead made available at runtime using the specified role name.

This is used for example to configure a Pageable object to be handled differently to other query arguments.

The parameter names of each role can be resolved from the MethodInvocationContext as a member of the DataMethod annotation where the member name is the role name.
