encapsulation. In short the class not only handles his work but also some other work
which is not his concern.
Ok now lets define crosscutting which is one of important aspect’s of AOP.
Twist :- What is cross cutting in AOP ?
When one or many concerns span across module its called as cross cutting.Example in
our audit trail example we will probably need to audit trail for customer as well as supplier.So
Audit trail can span across other objects also that is termed as cross cutting.
Below are both the classes actually implemented as per class diagram 8.7. If you see the
“Update” method of the customer class , its doing both of the concerns that is checking
for customer code length and also maintaining the audit trail using the audit trail class.
Public Class ClsCustomer
Private pstrCustcode As String
Private pstrCustName As String
Public Property Code() As String
Get
Return pstrCustcode
End Get
Set(ByVal Value As String)
pstrCustcode = Value
End Set
End Property
Public Property CustomerName() As String
Get
Return pstrCustName
End Get
Set(ByVal Value As String)
