Definition
Namespace: FolkerKinzel.VCards.BuilderParts
Assembly: FolkerKinzel.VCards (in FolkerKinzel.VCards.dll) Version: 8.0.1+a91cc3f0fd39aeb548e16006a60ca9dd10a304a2
The VCardBuilder instance that initialized this NameViewsBuilder to be able to chain calls.
Assembly: FolkerKinzel.VCards (in FolkerKinzel.VCards.dll) Version: 8.0.1+a91cc3f0fd39aeb548e16006a60ca9dd10a304a2
C#
public VCardBuilder ToDisplayNames(
INameFormatter nameFormatter
)VB
Public Function ToDisplayNames (
nameFormatter As INameFormatter
) As VCardBuilderC++
public:
VCardBuilder^ ToDisplayNames(
INameFormatter^ nameFormatter
)F#
member ToDisplayNames :
nameFormatter : INameFormatter -> VCardBuilder Parameters
- nameFormatter INameFormatter
Return Value
VCardBuilderThe VCardBuilder instance that initialized this NameViewsBuilder to be able to chain calls.
Remarks
The NameProperty instances are processed ordered by their Preference value. Empty NameProperty instances will be skipped. If a TextProperty instance that is not empty and has the same Language is still in DisplayNames, the corresponding NameProperty instance will be skipped.
The newly created TextProperty instances will have their Derived property set to true. The values of their Group property will be taken from the NameProperty instances.
Empty NameProperty instances will be skipped.
