public IntroductionInfoSupport()
Method Detail

suppressInterface

public void suppressInterface(java.lang.Class intf)
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:
intf - the interface to suppress

getInterfaces

public java.lang.Class[] getInterfaces()
Description copied from interface: IntroductionInfo
Return the additional interfaces introduced by this Advisor or Advice.

Specified by:
getInterfaces in interface IntroductionInfo
Returns:
the introduced interfaces

implementsInterface

public boolean implementsInterface(java.lang.Class ifc)
Check whether the specified interfaces is a published introduction interface.

Parameters:
ifc - the interface to check
Returns:
whether the interface is part of this introduction

implementInterfacesOnObject

protected void implementInterfacesOnObject(java.lang.Object delegate)
Publish all interfaces that the given delegate implements at the proxy level.

Parameters:
delegate - the delegate object

isMethodOnIntroducedInterface

protected final boolean isMethodOnIntroducedInterface(org.aopalliance.intercept.MethodInvocation mi)
Is this method on an introduced interface?

Parameters:
mi - the method invocation
Returns:
whether the invoked method is on an introduced interface
