Method Detail

extractGenericReturnType

public static Class extractGenericReturnType(Class type,
                                             Method method)

Analyzes the method (often defined in a base class) in the context of a particular concrete implementation of the class to establish the generic type of a property. This works when the property type is defined as a class generic parameter.

Parameters:

type - base type for evaluation

method - method (possibly from a base class of type) to extract

Returns:

the generic type if it may be determined, or the raw type (that is, with type erasure, most often Object)
