Parameters:

clazz - class with generic type arguments

generics - concrete types used to instantiate the class

Returns:

new scope for type parameters

private Class<?> getTypeVarConcreteClass(Class[] generics,
 int typeVarNum,
 String typeVarName)

Class[] computeFieldGenerics(Type fieldGenericType,
 Field field,
 Class[] fieldClass)

newCachedFieldOfGenericType

FieldSerializer.CachedField newCachedFieldOfGenericType(Field field,
 int accessIndex,
 Class[] fieldClass,
 Type fieldGenericType)

Special processing for fiels of generic types

getGenerics

public static Class[] getGenerics(Type genericType,
 Kryo kryo)

Returns the first level of classes or interfaces for a generic type.

Returns:

null if the specified type is not generic or its generic types are not classes.
