Method Summary

Modifier and Type	Method	Description
private AnnotationInvocationHandler	asOneOfUs(Object o)	Returns an object's invocation handler if that object is a dynamic proxy with a handler of type AnnotationInvocationHandler.
private static Object	cloneArray(Object array)	This method, which clones its array argument, would not be necessary if Cloneable had a public clone method.
private Boolean	equalsImpl(Object o)	Implementation of dynamicProxy.equals(Object o)
private Method[]	getMemberMethods()	Returns the member methods for our annotation type.
private int	hashCodeImpl()	Implementation of dynamicProxy.hashCode()
Object	invoke(Object proxy, Method method, Object[] args)
private static boolean	memberValueEquals(Object v1, Object v2)	Returns true iff the two member values in "dynamic proxy return form" are equal using the appropriate equality function depending on the member type.
private static int	memberValueHashCode(Object value)	Computes hashCode of a member value (in "dynamic proxy return form")
private static String	memberValueToString(Object value)	Translates a member value (in "dynamic proxy return form") into a string
private void	readObject(ObjectInputStream s)
private String	toStringImpl()	Implementation of dynamicProxy.toString()

Method Details

invoke

public Object invoke(Object proxy,
 Method method,
 Object[] args)

Specified by:

invoke in interface InvocationHandler

cloneArray

private static Object cloneArray(Object array)

This method, which clones its array argument, would not be necessary if Cloneable had a public clone method.

toStringImpl

private String toStringImpl()

Implementation of dynamicProxy.toString()

memberValueToString

private static String memberValueToString(Object value)

Translates a member value (in "dynamic proxy return form") into a string

equalsImpl

private Boolean equalsImpl(Object o)

Implementation of dynamicProxy.equals(Object o)

asOneOfUs

private AnnotationInvocationHandler asOneOfUs(Object o)

Returns an object's invocation handler if that object is a dynamic proxy with a handler of type AnnotationInvocationHandler. Returns null otherwise.

memberValueEquals

private static boolean memberValueEquals(Object v1,
 Object v2)

Returns true iff the two member values in "dynamic proxy return form" are equal using the appropriate equality function depending on the member type. The two values will be of the same type unless one of the containing annotations is ill-formed. If one of the containing annotations is ill-formed, this method will return false unless the two members are identical object references.

getMemberMethods

private Method[] getMemberMethods()

Returns the member methods for our annotation type. These are obtained lazily and cached, as they're expensive to obtain, and we only need them if our `equals` method is invoked (which should be rare).

hashCodeImpl

private int hashCodeImpl()

Implementation of dynamicProxy.hashCode()

memberValueHashCode

private static int memberValueHashCode(Object value)

Computes hashCode of a member value (in "dynamic proxy return form")

readObject

private void readObject(ObjectInputStream s)
                 throws IOException,
ClassNotFoundException

Throws:

IOException

ClassNotFoundException
