這篇文章主要為大家展示了“VBS如何實現(xiàn)ArrayList Class vbs中的數(shù)組類”,內(nèi)容簡而易懂,條理清晰,希望能夠幫助大家解決疑惑,下面讓小編帶領大家一起研究并學習一下“VBS如何實現(xiàn)ArrayList Class vbs中的數(shù)組類”這篇文章吧。
Class ArrayList
Private items()
Private size
Private Sub Class_Initialize
size = 0
ReDim items(1)
End Sub
Private Sub Class_Terminate
items = null
End Sub
Public Function Add(ByVal value)
If (size = Ubound(items)) Then EnsureCapacity((size + 1))
items(size) = value
size = size + 1
Add = size
End Function
Public Property Get Item(index)
Item = items(index)
End Property
Public Property Let Item(index, vObject)
items(index) = vObject
End Property
Property Get Count
Count = size
End Property
Public Property Get Capacity()
Capacity = Ubound(items)
End Property
Public Property Let Capacity(value)
If (value <> Ubound(items)) Then
If (value < size) Then Err.Rise 6
If (value > 0) Then
ReDim Preserve items(value)
Else
ReDim Preserve items(3)
End If
End If
End Property
Private Sub EnsureCapacity(ByVal min)
If (Ubound(items) < min) Then
Dim num1 : num1 = IIf((Ubound(items) = 0), 4, (Ubound(items) * 2))
If (num1 < min) Then num1 = min
Capacity = num1
End If
End Sub
Private Function IIf(j, r1, r2)
IF (j) Then
IIf = r1
Else
IIf = r2
End IF
End Function
End Class
示例:
Dim al : Set al = new ArrayList
al.Add(1)
al.Add(2)
al.Add(3)
al.Add(4)
al.Add(5)
al.Add(6)
al.Add(7)
al.Add(8)
al.Add(9)
al.Add(10)
For i = 0 To al.Count -1
w("Index"& i &": "& al.Item(i))
Next
w("Count: "& al.Count)
w("Capacity: "& al.Capacity)
Sub w(o)
Response.Write(o &"<br />")
End Sub
