How to create a composite aspect, i.e. combining multiple aspects into a single one?

[ziriax]

Suppose I have many methods, all with the aspects [Log] and [Cache].

How can I create a new aspect say called QueryAttribute that is the composite of these two?

What we call composite aspects are aspects that combine several pieces of advice. This is covered in the conceptual documentation. Basically you need to implement the BuildAspect.

However in your specific case, your implementation of QueryAttribute.OverrideMethod must combine the logic of both aspects in a single template.

Another approach is to have QueryAttribute provide Log and Cache as child aspects.

Thanks for the prompt answer! Indeed I want to reuse the excellent aspect attributes you provide in the Patterns package, chaining several of these aspects into an aspect class. I will try the child approach.
