@Beta public abstract class AbstractInvocationHandler extends java.lang.Object implements java.lang.reflect.InvocationHandler
InvocationHandler that handles Object.equals(java.lang.Object),
Object.hashCode() and Object.toString(). For example:
class Unsupported extends AbstractInvocationHandler {
protected Object handleInvocation(
Object proxy, Method method, Object[] args) {
throw new UnsupportedOperationException();
}
}
CharSequence unsupported = Reflection.newProxy(CharSequence.class, new Unsupported());

AbstractInvocationHandler() |
| Modifier and Type | Method and Description |
|---|---|
boolean |
equals(java.lang.Object obj)
By default delegates to
Object.equals(java.lang.Object) so instances are only equal if they are
identical. |
protected abstract java.lang.Object |
handleInvocation(java.lang.Object proxy,
java.lang.reflect.Method method,
java.lang.Object[] args)
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(). |
int |
hashCode()
By default delegates to
Object.hashCode(). |
java.lang.Object |
invoke(java.lang.Object proxy,
java.lang.reflect.Method method,
java.lang.Object[] args) |
java.lang.String |
toString()
By default delegates to
Object.toString(). |
public final java.lang.Object invoke(java.lang.Object proxy,
java.lang.reflect.Method method,
@Nullable
java.lang.Object[] args)
throws java.lang.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
equals(java.lang.Object) returns true for the InvocationHandler of argument
handleInvocation(java.lang.Object, java.lang.reflect.Method, java.lang.Object[]).
invoke in interface java.lang.reflect.InvocationHandlerjava.lang.Throwableprotected abstract java.lang.Object handleInvocation(java.lang.Object proxy,
java.lang.reflect.Method method,
java.lang.Object[] args)
throws java.lang.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.
java.lang.Throwablepublic boolean equals(java.lang.Object obj)
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

Subclasses can override this method to provide custom equality.

Object.hashCode(). The dynamic proxies' hashCode() will
delegate to this method. Subclasses can override this method to provide custom equality.hashCode in class java.lang.Objectpublic java.lang.String toString()
