LotusScript提升大字符串拼接函数（功能类似java中StringBuffer）

LotusScript提升大字符串拼接函数（功能类似java中StringBuffer），代码如下：

Class StringBuffer
        Public count As Integer        
        Private arr() As String
        Private size As Integer
        Private increment As Integer
        
        Sub New(Byval a As Integer)
                Redim arr(a)
                increment=a
                count=0
        End Sub
        
        Sub add(Byval a As String)
                Me.push a
        End Sub        
        
        Sub push(Byval a As String)
                size=Ubound(arr())
                If count>=size Then
                        Redim Preserve arr(size+increment)
                End If
                arr(count)=a
                count=count+1
        End Sub
        
        Function collapse(Byval a As String) As String
                Dim sTemp As String
                If count>0 Then
                        Redim Preserve arr(count-1)        
                        sTemp=Join(arr, a)
                End If
                collapse=sTemp
        End Function
        
        Function getArray() As Variant
                If count>0 Then
                        Redim Preserve arr(count-1)
                Else
                        Redim arr(0)
                End If
                getArray=arr
        End Function
        
        Function clear
                count=0
        End Function
End Class
