function ~IAsyncResourceResponse #

virtual ~IAsyncResourceResponse()

function GetSpace #

virtual void * GetSpace(
    unsigned long long size
) =0

Allocates more space where to put the data read. NB: You can call the function multiple times and it’ll allocate more space if needed. The space requested MUST be the SUM of all space required. Already copied data will be still available in the buffer - it works the same way as “realloc”.

Note: The pointer returned will always point to the beginning of the data array. Users have to keep an offset counter themselves if they plan to call GetSpace() multiple times.

function ReceiveUserImage #

virtual void ReceiveUserImage(
    const UserImageData & userImageData
) =0

Passes data about a user image that is ready to be used by the UI system. This lets Cohtml use textures that are already on the GPU and the void* is interpreted by the backend.

Parameters:

• userImageData information about the user image

function ReceiveOptimizedData #

virtual void ReceiveOptimizedData(
    const DataBuffer * optimizedData
) =0

Passes optimized data that speeds up the resource processing.

Parameters:

• optimizedData is a data, produced by doing resource processing ahead of time and can be easily cached, serialized and deserialized.

Note: Currently, this can speed up the JavaScript compilation and run times, the optimizedData can be obtained using the cohtml::ScriptCompiler::Compile.

function SignalProgress #

virtual void SignalProgress() =0

Can be called when part of the response is ready and can be used by the backend. Calling this is optional. Note that the pointer returned by GetSpace will not be valid anymore. The user will have to request some more memory for the fresh data after this call.

function SetStatus #

virtual void SetStatus(
    unsigned short status
) =0

Additional API used for complex responses like HTTP. Setting these fields is not required for local “coui” loads.

function SetResponseURL #

virtual void SetResponseURL(
    const char * responseURL
) =0

The URL of the response (can change from the request due to redirects)

function SetHeader #

virtual void SetHeader(
    const char * name,
    const char * value
) =0

Set a response header.

function Finish #

virtual void Finish(
    Status status
) =0

Call when the resource has been loaded or the load failed. After this call the object is invalidated. NB: It’s not safe to call any methods on this interface after Finish.
