Method Summary

static java.lang.String	canBeABeanType(java.lang.Class<?> type)
static void	checkAndFixAccess(java.lang.reflect.Member member) Method called to check if we can use the passed method or constructor (wrt access restriction -- public methods can be called, others usually not); and if not, if there is a work-around for the problem.
static java.util.List<java.lang.Class<?>>	findSuperTypes(java.lang.Class<?> cls, java.lang.Class<?> endBefore) Method that will find all sub-classes and implemented interfaces of a given class or interface.
static boolean	isConcrete(java.lang.Class<?> type) Helper method that checks if given class is a concrete one; that is, not an interface or abstract class.
static java.lang.String	isLocalType(java.lang.Class<?> type)
static boolean	isProxyType(java.lang.Class<?> type) Helper method used to weed out dynamic Proxy types; types that do not expose concrete method API that we could use to figure out automatic Bean (property) based serialization.

Method Detail

findSuperTypes

public static java.util.List<java.lang.Class<?>> findSuperTypes(java.lang.Class<?> cls,
                                                                java.lang.Class<?> endBefore)

Method that will find all sub-classes and implemented interfaces of a given class or interface. Classes are listed in order of precedence, starting with the immediate super-class, followed by interfaces class directly declares to implemented, and then recursively followed by parent of super-class and so forth. Note that Object.class is not included in the list regardless of whether endBefore argument is defined

Parameters:

endBefore - Super-type to NOT include in results, if any; when encountered, will be ignored (and no super types are checked).

canBeABeanType

public static java.lang.String canBeABeanType(java.lang.Class<?> type)

Returns:

Null if class might be a bean; type String (that identifies why it's not a bean) if not

isLocalType

public static java.lang.String isLocalType(java.lang.Class<?> type)

isProxyType

public static boolean isProxyType(java.lang.Class<?> type)

Helper method used to weed out dynamic Proxy types; types that do not expose concrete method API that we could use to figure out automatic Bean (property) based serialization.

isConcrete

public static boolean isConcrete(java.lang.Class<?> type)

Helper method that checks if given class is a concrete one; that is, not an interface or abstract class.

checkAndFixAccess

public static void checkAndFixAccess(java.lang.reflect.Member member)

Method called to check if we can use the passed method or constructor (wrt access restriction -- public methods can be called, others usually not); and if not, if there is a work-around for the problem.
