All Implemented Interfaces:

InvocationHandler

@Beta
@Deprecated(since="2022-12-01")
public abstract class AbstractInvocationHandler
extends Object
implements InvocationHandler

Deprecated.

The Google Guava Core Libraries are deprecated and will not be part of the AEM SDK after April 2023

Abstract implementation of 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());
  

Since:

Method Details

invoke

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

Deprecated.

• 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

equals

public boolean equals(Object obj)

Deprecated.

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()

Deprecated.

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()

Deprecated.

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
