Method Detail

• invoke

  public final Object invoke(Object proxy,
              Method method,
              @Nullable
              Object[] args)
                      throws Throwable

  • proxy.hashCode() delegates to hashCode()
  • proxy.toString() delegates to toString()
  • proxy.equals(argument) returns true if:
    • proxy and argument are of the same type
    • and equals(java.lang.Object) returns true for the InvocationHandler of argument
  • other method calls are dispatched to handleInvocation(java.lang.Object, java.lang.reflect.Method, java.lang.Object[]).

  Specified by:

  invoke in interface InvocationHandler

  Throws:

  Throwable

• handleInvocation

  protected abstract Object handleInvocation(Object proxy,
                        Method method,
                        Object[] args)
                                      throws Throwable

  invoke(java.lang.Object, java.lang.reflect.Method, java.lang.Object[]) delegates to this method upon any method invocation on the proxy instance, except Object.equals(java.lang.Object), Object.hashCode() and Object.toString(). The result will be returned as the proxied method's return value.

  Unlike invoke(java.lang.Object, java.lang.reflect.Method, java.lang.Object[]), args will never be null. When the method has no parameter, an empty array is passed in.

  Throws:

  Throwable

• equals

  public boolean equals(Object obj)

  By default delegates to Object.equals(java.lang.Object) so instances are only equal if they are identical. proxy.equals(argument) returns true if:

  • proxy and argument are of the same type
  • and this method returns true for the InvocationHandler of argument

  Subclasses can override this method to provide custom equality.

  Overrides:

  equals in class Object

• hashCode

  public int hashCode()

  By default delegates to Object.hashCode(). The dynamic proxies' hashCode() will delegate to this method. Subclasses can override this method to provide custom equality.

  Overrides:

  hashCode in class Object

• toString

  public String toString()

  By default delegates to Object.toString(). The dynamic proxies' toString() will delegate to this method. Subclasses can override this method to provide custom string representation for the proxies.

  Overrides:

  toString in class Object
