Generics

Zašto Generics?

• Kod tipiziran
• Izbegnute run-time greške
• IntelliSense radi
• Bolje performanse
• Primer Efikasnost realizacije primenom
• Array 344
• ArrayList 4656
• Generic List 797

14
Partial Types
File Class1.vb Public Class Car Public Sub
Start() End Sub End Class
Dim T As New Car() T.Start() T.Stop()
File Class2.vb Public Partial Class Car Public
Sub Stop() End Sub End Class
15
IsNot Operator
Public Sub Test(ByVal o As SomeType) If Not o
Is Nothing Then o.DoSomething() Else
Throw New NullReferenceException() End If End
Sub
Public Sub Test(ByVal o As SomeType) If o IsNot
Nothing Then o.DoSomething() Else Throw
New NullReferenceException() End If End Sub

Overloading operatora
Public Class SetPoint Public Temperature as
Single Public Sub New (value as Single)
Me.Temperaturevalue End Sub Public Shared
Operator (ByVal a As SetPoint,_ ByVal b
As SetPoint) As SetPoint Return New
SetPoint(a.Temperature b.Temperature) End
Operator End Class
Public Class SetPoint Public Temperature as
Single Public Sub New (value as Single)
Me.Temperaturevalue End SubEnd Class
Dim T1 as New SetPoint(12.5)Dim T2 as New
SetPoint(13)Dim T3 as SetPoint T1 T2
18
Overloading operatora(2)
Public Class Complex Public Real As Double
Public Imag As Double Public Sub New(ByVal rp
As Double, ByVal ip As Double) Real rp
Imag ip End Sub Shared Operator (ByVal
lhs As Complex, ByVal rhs As Complex)_ As
Complex Return New Complex(lhs.Real
rhs.Real, lhs.Imag rhs.Imag) End Operator End
Class 'new Complex operator works
intuitively Dim lhs As Complex New
Complex(2.1, 3.3) Dim rhs As Complex New
Complex(2.5, 4.6) Dim res As Complex lhs
rhs 'res.real 4.6, res.imag 7.9
