Methods

At<TDocument, TConverter, TValue, TValueConverter>(Attr<TDocument, TConverter>, Attr<TValue, TValueConverter>)

Gets an attribute inside a nested document, by the handle that its document type generates: Order.Attrs.ShipTo.At(Address.Attrs.City) has the path ShipTo.City, and it can go on from there. A handle that names a whole document stays an ordinary attribute, which is why this is a call: Set(Order.Attrs.ShipTo, address) replaces the map.

public static Attr<TValue, TValueConverter> At<TDocument, TConverter, TValue, TValueConverter>(this Attr<TDocument, TConverter> document, Attr<TValue, TValueConverter> attribute) where TDocument : IDynamoDbDocument<TDocument> where TConverter : IDynamoDbConverter<TDocument> where TValueConverter : IDynamoDbConverter<TValue>

Parameters

document Attr<TDocument, TConverter>

The attribute that holds the document.

attribute Attr<TValue, TValueConverter>

The attribute inside the document, a name or a path. Nothing checks that it belongs to TDocument.

Returns

Attr<TValue, TValueConverter>

The attribute at the nested path.

Type Parameters

TDocument

The document. A handle of a scalar has nothing inside, so it does not compile.

TConverter

The converter of the document.

TValue

The type of the inner attribute.

TValueConverter

The converter of the inner attribute.

BeginsWith(Attr<bool, BoolConverter>, string)

Does not compile, because DynamoDB finds nothing with begins_with on a boolean.

Contains(Attr<string, StringConverter>, string)

Checks with contains whether a string holds a substring, compared by bytes, so case matters. An attribute that does not exist holds nothing, so the condition fails there and its Negate() holds.

The substring.

Returns

Contains<string, StringConverter>

Returns

Contains<T, SetElementValueConverter<T, TElement>>

The condition.

Type Parameters

T

The element type.

TElement

The converter of the elements, which writes the operand as the set stores it.

Contains<T, TConverter>(Attr<List<T>, ListConverter<T, TConverter>>, T)

Checks with contains whether a list holds an element equal to the value, which DynamoDB compares by type and value. An attribute that does not exist holds nothing, so the condition fails there and its Negate() holds.
