- Parameters:
aField
- the field being updatedwithinCode
- the Method or Constructor owning the call site
- Returns:
- a ShadowMatch indicating whether the pointcut always, sometimes, or never matches field get join points for the given field and call site.
public ShadowMatch matchesFieldSet(Field aField, Class withinType)
Determine whether or not this pointcut matches a set of the given field outside of the scope of any method or constructor, but within the given type (for example, during static initialization).
- Parameters:
aField
- the field being updatedwithinType
- the type owning the call site
