ChangeUnitListFilterInfo 建構 (SyncIdFormatGroup, 泛型 ICollection, Boolean)

初始化 ChangeUnitListFilterInfo 類別的新執行個體，這個執行個體包含指定的識別碼格式結構描述、指出這個篩選包含哪些變更單位之變更單位識別碼的集合，以及指出此篩選是否會套用至範圍內所有項目的值。

Public Sub New ( _
    idFormats As SyncIdFormatGroup, _

'用途
Dim idFormats As SyncIdFormatGroup
Dim changeUnitIds As ICollection(Of SyncId)
Dim appliesToAllItems As Boolean

Dim instance As New ChangeUnitListFilterInfo(idFormats, changeUnitIds, appliesToAllItems)

public ChangeUnitListFilterInfo (
    SyncIdFormatGroup idFormats,
    ICollection<SyncId> changeUnitIds,
    bool appliesToAllItems
)

public:
ChangeUnitListFilterInfo (
    SyncIdFormatGroup^ idFormats, 
    ICollection<SyncId^>^ changeUnitIds, 
    bool appliesToAllItems
)

public ChangeUnitListFilterInfo (
    SyncIdFormatGroup idFormats, 
    ICollection<SyncId> changeUnitIds, 
    boolean appliesToAllItems
)

public function ChangeUnitListFilterInfo (
    idFormats : SyncIdFormatGroup, 
    changeUnitIds : ICollection<SyncId>, 
    appliesToAllItems : boolean
)

參數

• idFormats
  提供者的識別碼格式結構描述。

• changeUnitIds
  指出這個篩選包含哪些變更單位之變更單位識別碼的集合。

• appliesToAllItems
  當此篩選會套用至範圍內的所有項目時，則為 true，否則為 false。

範例

下列範例會建立要包含在同步處理中的變更單位識別碼清單，並且用這個變更單位識別碼清單來建立 ChangeUnitListFilterInfo 物件。ChangeUnitListFilterInfo 物件會傳遞給 GetFilteredChangeBatch 方法，用來從中繼資料儲存服務擷取篩選的變更批次。

Public Sub SetContactFieldsToInclude(ByVal includedFields As Contact.ChangeUnitFields())
    ' Translate the array of fields to a list of IDs.
    _includedChangeUnits = New List(Of SyncId)(includedFields.Length)
    For iField As Integer = 0 To includedFields.Length - 1
        _includedChangeUnits.Add(New SyncId(CByte(includedFields(iField))))
    Next

    _isFiltered = True
End Sub
Public Overrides Function GetChangeBatch(ByVal batchSize As UInteger, ByVal destinationKnowledge As SyncKnowledge, ByRef changeDataRetriever As Object) As ChangeBatch
    ' Return this object as the IChangeDataRetriever object that is called to retrieve item data.
    changeDataRetriever = Me

    Dim retrievedBatch As ChangeBatch
    If _isFiltered Then
        ' Use the metadata storage service to get a filtered batch of changes.
        Dim filterInfo As New ChangeUnitListFilterInfo(IdFormats, _includedChangeUnits, True)
        retrievedBatch = _ContactStore.ContactReplicaMetadata.GetFilteredChangeBatch(batchSize, destinationKnowledge, filterInfo, Nothing)
    Else
        ' Use the metadata storage service to get a batch of changes.
        retrievedBatch = _ContactStore.ContactReplicaMetadata.GetChangeBatch(batchSize, destinationKnowledge)
    End If

    Return retrievedBatch
End Function

public void SetContactFieldsToInclude(Contact.ChangeUnitFields[] includedFields)
{
    // Translate the array of fields to a list of IDs.
    _includedChangeUnits = new List<SyncId>(includedFields.Length);
    for (int iField = 0; iField < includedFields.Length; iField++)
    {
        _includedChangeUnits.Add(new SyncId((byte)includedFields[iField]));
    }

    _isFiltered = true;
}

public override ChangeBatch GetChangeBatch(uint batchSize, SyncKnowledge destinationKnowledge, out object changeDataRetriever)
{
    // Return this object as the IChangeDataRetriever object that is called to retrieve item data.
    changeDataRetriever = this;

    ChangeBatch retrievedBatch;
    if (_isFiltered)
    {
        // Use the metadata storage service to get a filtered batch of changes.
        ChangeUnitListFilterInfo filterInfo = new ChangeUnitListFilterInfo(IdFormats, _includedChangeUnits, true);
        retrievedBatch = _ContactStore.ContactReplicaMetadata.GetFilteredChangeBatch(batchSize, destinationKnowledge,
            filterInfo, null);
    }
    else
    {
        // Use the metadata storage service to get a batch of changes.
        retrievedBatch = _ContactStore.ContactReplicaMetadata.GetChangeBatch(batchSize, destinationKnowledge);
    }
    
    return retrievedBatch;
}
