ru.vyarus.java.generics.resolver.util.UnknownGenericException

All Implemented Interfaces:

java.io.Serializable

public class UnknownGenericException
extends java.lang.RuntimeException

Thrown during type resolution when found generic name is not declared. Could appear in two situations:

• Type resolved in context of different class (usage error).
• Type contains method generic. For example, in method <T> void doSmth(List<T> arg1) if we try to resolve generic of arg1, it will fail, because generic T is only known within method scope (resolve parameters and resolve method return type api correctly support such generics, but its hard to support it in general case).
