ru.vyarus.java.generics.resolver.error.WrongGenericsContextException

All Implemented Interfaces:

java.io.Serializable

public class WrongGenericsContextException
extends GenericSourceException

Thrown to indicate generics not resolvable under current context class (because generics could use the same names and incorrect context could lead to hard to track errors). Thrown only on methods inside AbstractGenericsContext where incoming type is explicitly checked for compatibility (to prevent usage errors).

Most common reason is trying to resolve type without changing context type (for example, when using getMethod() or getField()).

Error message contains usage hint if it is possible to resolve type correctly.
