Method Detail

ultimateTargetClass

public static Class<?> ultimateTargetClass(Object candidate)

Determine the ultimate target class of the given instance, traversing not only a top-level proxy but any number of nested proxies as well — as long as possible without side effects.

Parameters:

candidate - the instance to check (might be a proxy)

Returns:

the ultimate target class (or the plain class of the given object as fallback; never null)

isProxy

public static boolean isProxy(Object object)

Check whether the given object is a proxy.

Parameters:

object - the object to check

isProxyMember

public static boolean isProxyMember(Member member,
                                    Object object)

Check whether the given member is a proxy member of a proxy object or is a static proxy member.

Parameters:

member - the member to check

object - the object to check

isHibernateProxy

public static boolean isHibernateProxy(Object object)

Check whether the given object is a Hibernate proxy.

Parameters:

object - the object to check

isHibernateProxyMember

public static boolean isHibernateProxyMember(Member member)

Check whether the given member is a member of a Hibernate proxy.

Parameters:

member - the member to check

getHibernateProxyTarget

public static Object getHibernateProxyTarget(Object object)

Returns:

the target instance of the given object if it is a Hibernate proxy object, otherwise the given object

resolveTargetMember

public static Member resolveTargetMember(Member proxyMember,
                                         Object target)

Returns:

matching member on target object if one exists, otherwise the same member
