getTemplateParameterOfInterface

public static java.lang.Class getTemplateParameterOfInterface(java.lang.Class base,
                                                              java.lang.Class desiredInterface)

getGenericReturnTypeOfGenericInterfaceMethod

public static java.lang.reflect.Type getGenericReturnTypeOfGenericInterfaceMethod(java.lang.Class clazz,
                                                                                  java.lang.reflect.Method method)
Given an interface Method, look in the implementing class for the method that implements the interface's method to obtain generic type information. This is useful for templatized interfaces like:

 interface Foo {

Parameters:
clazz -
method - interface method
Returns:

getGenericParameterTypesOfGenericInterfaceMethod

public static java.lang.reflect.Type[] getGenericParameterTypesOfGenericInterfaceMethod(java.lang.Class clazz,
                                                                                        java.lang.reflect.Method method)
Given an interface Method, look in the implementing class for the method that implements the interface's method to obtain generic type information. This is useful for templatized interfaces like:

 interface Foo {

Parameters:
clazz -
method - interface method
Returns:

getRawType

public static java.lang.Class<?> getRawType(java.lang.reflect.Type type)

getRawTypeNoException

public static java.lang.Class<?> getRawTypeNoException(java.lang.reflect.Type type)

getTypeArgument

public static java.lang.Class<?> getTypeArgument(java.lang.reflect.Type genericType)
Returns the type argument from a parameterized type

Parameters:
genericType -
Returns:
null if there is no type parameter

getCollectionBaseType

public static java.lang.Class getCollectionBaseType(java.lang.Class type,
                                                    java.lang.reflect.Type genericType)

getMapKeyType

public static java.lang.Class getMapKeyType(java.lang.reflect.Type genericType)

getMapValueType

public static java.lang.Class getMapValueType(java.lang.reflect.Type genericType)
