Create operations to access $value for media type entities & stream typed properties and functions

[darrelmiller]

The following CSDL

<edmx:Edmx xmlns:edmx="http://docs.oasis-open.org/odata/ns/edmx" Version="4.0">
<edmx:DataServices>
<Schema xmlns="http://docs.oasis-open.org/odata/ns/edm" Namespace="microsoft.graph" >

    <EntityContainer Name="TodoService">
        <EntitySet Name="Todos" EntityType="microsoft.graph.Todo">
        </EntitySet>
    </EntityContainer>
    
    <EntityType Name="Todo" HasStream="true">
            <Key>
                <PropertyRef Name="Id"/>
            </Key>
        <Property Name="Id" Type="Edm.String"/>
        <Property Name="Logo" Type="Edm.Stream"/>
        <Property Name="Description" Type="Edm.String"/>
    </EntityType>

</Schema>
</edmx:DataServices>
</edmx:Edmx>

should create the following operations,

/Todos
/Todos/{Todo-Id}
/Todos/{Todo-Id}/$value   (operationId = Todos_GetTodoContent)
/Todos/{Todo-Id}/Logo    (operationId = Todos_GetTodoLogo)

Entities with HasStream=true should create a URL to the $value of the entity. Properties that are of type Stream should have an operation that allows directly accessing the property.

Also consider stream typed properties on the response type of a composable function:

<Function Name="deviceConfigurationUserActivity" IsBound="true" IsComposable="true">
<Parameter Name="bindingParameter" Type="graph.reportRoot"/>
<ReturnType Type="graph.report"/>
</Function>

<ComplexType Name="report">
<Property Name="content" Type="Edm.Stream"/>
</ComplexType>

This allows the path:

GET https://graph.microsoft.com/v1.0/reports/deviceConfigurationUserActivity/Content

and so we should generate an operation for GetReportsDeviceConfigurationUserActivityContent

[darrelmiller]

If an EntityType has hasStream=true and has a content property, then don't generate an operation for the the $value endpoint, just for the content property. e.g.

<EntityType Name="onenotePage" BaseType="graph.onenoteEntitySchemaObjectModel" HasStream="true">
<Property Name="title" Type="Edm.String"/>
<Property Name="createdByAppId" Type="Edm.String"/>
<Property Name="links" Type="graph.pageLinks"/>
<Property Name="contentUrl" Type="Edm.String"/>
<Property Name="content" Type="Edm.Stream"/>
<Property Name="lastModifiedDateTime" Type="Edm.DateTimeOffset"/>
<Property Name="level" Type="Edm.Int32"/>
<Property Name="order" Type="Edm.Int32"/>
<Property Name="userTags" Type="Collection(Edm.String)"/>
<NavigationProperty Name="parentSection" Type="graph.onenoteSection" ContainsTarget="true"/>
<NavigationProperty Name="parentNotebook" Type="graph.notebook" ContainsTarget="true"/>
</EntityType>
