invoke	back to summary
public Object invoke(Object proxy, Method method, Object[] args) Implements java.lang.reflect.InvocationHandler.invoke. Doc from java.lang.reflect.InvocationHandler.invoke. Processes a method invocation on a proxy instance and returns the result. This method will be invoked on an invocation handler when a method is invoked on a proxy instance that it is associated with. Parameters proxy:Object the proxy instance that the method was invoked on method:Method the `Method` instance corresponding to the interface method invoked on the proxy instance. The declaring class of the `Method` object will be the interface that the method was declared in, which may be a superinterface of the proxy interface that the proxy class inherits the method through. args:Object[] an array of objects containing the values of the arguments passed in the method invocation on the proxy instance, or `null` if interface method takes no arguments. Arguments of primitive types are wrapped in instances of the appropriate primitive wrapper class, such as `java.lang.Integer` or `java.lang.Boolean`. Returns:Object the value to return from the method invocation on the proxy instance. If the declared return type of the interface method is a primitive type, then the value returned by this method must be an instance of the corresponding primitive wrapper class; otherwise, it must be a type assignable to the declared return type. If the value returned by this method is `null` and the interface method's return type is primitive, then a `NullPointerException` will be thrown by the method invocation on the proxy instance. If the value returned by this method is otherwise not compatible with the interface method's declared return type as described above, a `ClassCastException` will be thrown by the method invocation on the proxy instance.

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

Implements java.lang.reflect.InvocationHandler.invoke.

Doc from java.lang.reflect.InvocationHandler.invoke.

Processes a method invocation on a proxy instance and returns the result. This method will be invoked on an invocation handler when a method is invoked on a proxy instance that it is associated with.

Parameters

proxy:Object: the proxy instance that the method was invoked on
method:Method: the Method instance corresponding to the interface method invoked on the proxy instance. The declaring class of the Method object will be the interface that the method was declared in, which may be a superinterface of the proxy interface that the proxy class inherits the method through.
args:Object[]: an array of objects containing the values of the arguments passed in the method invocation on the proxy instance, or null if interface method takes no arguments. Arguments of primitive types are wrapped in instances of the appropriate primitive wrapper class, such as java.lang.Integer or java.lang.Boolean.

Returns:Object

the value to return from the method invocation on the proxy instance. If the declared return type of the interface method is a primitive type, then the value returned by this method must be an instance of the corresponding primitive wrapper class; otherwise, it must be a type assignable to the declared return type. If the value returned by this method is null and the interface method's return type is primitive, then a NullPointerException will be thrown by the method invocation on the proxy instance. If the value returned by this method is otherwise not compatible with the interface method's declared return type as described above, a ClassCastException will be thrown by the method invocation on the proxy instance.

isPrintableAscii	back to summary
private static boolean isPrintableAscii(char ch) Is a character printable ASCII?

memberValueEquals	back to summary
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.

memberValueEquals

back to summary

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.

memberValueHashCode	back to summary
private static int memberValueHashCode(Object value) Computes hashCode of a member value (in "dynamic proxy return form")

memberValues	back to summary
pack-priv Map<String, Object> memberValues() Gets an unmodifiable view on the member values.

memberValueToString	back to summary
private static String memberValueToString(Object value) Translates a member value (in "dynamic proxy return form") into a string.

quote	back to summary
private static String quote(char ch) Escapes a character if it has an escape sequence or is non-printable ASCII. Leaves non-ASCII characters alone.

toStringImpl	back to summary
private String toStringImpl() Implementation of dynamicProxy.toString()

validateAnnotationMethods	back to summary
private void validateAnnotationMethods(Method[] memberMethods) Validates that a method is structurally appropriate for an annotation type. As of Java SE 8, annotation types cannot contain static methods and the declared methods of an annotation type must take zero arguments and there are restrictions on the return type.
