the delegate object
delegate)

Publish all interfaces that the given delegate implements at the proxy level.

public boolean

Returns:

whether the interface is part of this introduction
implementsInterface(Class<?>
the interface to check
ifc)

Check whether the specified interfaces is a published introduction interface.

protected final boolean

Returns:

whether the invoked method is on an introduced interface
isMethodOnIntroducedInterface(MethodInvocation
the method invocation
mi)

Is this method on an introduced interface?

private void
readObject(ObjectInputStream ois)

This method is implemented only to restore the logger.

public void
suppressInterface(Class<?>
the interface to suppress
ifc)

Suppress the specified interface, which may have been autodetected due to the delegate implementing it.

Doc from org.springframework.aop.IntroductionInfo.getInterfaces.

Return the additional interfaces introduced by this Advisor or Advice.

Returns:Class<?>[]

the introduced interfaces

implementInterfacesOnObjectback to summary
protected void implementInterfacesOnObject(Object delegate)

Publish all interfaces that the given delegate implements at the proxy level.

Parameters
delegate:Object

the delegate object

implementsInterfaceback to summary
public boolean implementsInterface(Class<?> ifc)

Check whether the specified interfaces is a published introduction interface.

Parameters
ifc:Class<?>

the interface to check

Returns:boolean

whether the interface is part of this introduction

isMethodOnIntroducedInterfaceback to summary
protected final boolean isMethodOnIntroducedInterface(MethodInvocation mi)

Is this method on an introduced interface?

Parameters
mi:MethodInvocation

the method invocation

Returns:boolean

whether the invoked method is on an introduced interface

readObjectback to summary
private void readObject(ObjectInputStream ois) throws IOException, ClassNotFoundException

This method is implemented only to restore the logger. We don't make the logger static as that would mean that subclasses would use this class's log category.

suppressInterfaceback to summary
public void suppressInterface(Class<?> ifc)

Suppress the specified interface, which may have been autodetected due to the delegate implementing it. Call this method to exclude internal interfaces from being visible at the proxy level.

Does nothing if the interface is not implemented by the delegate.

Parameters
ifc:Class<?>

the interface to suppress
