XSICollection.Unique

このコレクションがユニークであるか（true）ないか（false）を示すBoolean 値を戻したり、設定したりします。あるコレクションがユニークであるとは、そのコレクションのオブジェクトがただ 1 つ含まれる（複製がない）場合を指します。ただし、異なるオブジェクトの場合は、ユニークなコレクション内に複数含めることができます。

注：デフォルトでは XSICollection は重複が許されます。ユニークなコレクションを取得するには、Unique フラグを明示的に True に設定する必要があります。コレクションがユニークになると、すべての複製が削除され、それ以降は複製を追加できません。

1. VBScript の例

Dim oColl		' object pointer for collection

' Create a non-unique collection as an ActiveX object

Set oColl = CreateObject("XSI.Collection")

' Add a bunch of duplicates

oColl.Add ActiveSceneRoot

oColl.Add ActiveSceneRoot

oColl.Add ActiveSceneRoot

oColl.Add ActiveSceneRoot

oColl.Add ActiveSceneRoot

' How many members are in this collection?

countMembers oColl

' Explicitly set

oColl.Unique = True

' Now how many members are in this collection?

countMembers oColl

'--------------------------------------------------

function countMembers( in_coll )

	' How many members are in this collection

	LogMessage "This collection contains " & in_coll.Count & " members."

end function

'--------------------------------------------------

' Output of above script:

'INFO : "This collection contains 5 members."

'INFO : "This collection contains 1 members."
