Constructors

CachedRowTransformation()

Declaration
{{< /rawhtml >}} ```C# public CachedRowTransformation() ``` {{< rawhtml >}}

CachedRowTransformation(Func<TInput, CachedData<TCache>, TOutput>)

Declaration
{{< /rawhtml >}} ```C# public CachedRowTransformation(Func, TOutput> transformationFunc) ``` {{< rawhtml >}}
Parameters
Type Name Description
Func<TInput, CachedData<TCache>, TOutput> transformationFunc
