Mapperプロパティ






このAnnContainerのためにマッパーを取得または設定します。
構文
public AnnContainerMapper Mapper {get; set;}
'Declaration
 
Public Property Mapper As AnnContainerMapper
public AnnContainerMapper Mapper {get; set;}
@property (nonatomic) LTAnnContainerMapper* mapper;
public AnnContainerMapper getMapper()
public void setMapper(AnnContainerMapper mapper)
            
 
get_Mapper();
set_Mapper(value);
Object.defineProperty('Mapper');

属性値

このAnnContainerのためのマッパー。デフォルト値は、AnnContainerMapper.CreateDefaultによって作成されるオブジェクトです。
解説

マッパーは、表示、コンテナとimage座標を変換するとき、このコンテナにより用いられます。詳細については、「AnnContainerMapper」を参照してください。

このプロパティの値をnullに設定するならば、このコンテナは代わりにAnnContainerMapper.CreateDefaultから作成されるオブジェクトを使います。したがって、このプロパティの値を問い合わせるとき、常に有効なオブジェクトを取得します。

サンプル

このサンプルでは、マッパーを使って長方形値をアノテーションから画像ユニットに変換し、戻します。
