API.
Purpose:
Stream-out operator.
Calling Context:
Called to stream out data.
Parameters:
- TStream & toWhere -The stream the object is streamed out to.
Return Value:
Returns a reference to the stream the object streams itself out to.

Member Function: TResolution::MatchResolution
virtual TGPoint MatchResolution (const TGPoint & resolution) const
Interface Category:
API.
Purpose:
For this device, find an available resolution that this device can accommodate, which is closest to the resolution requested. Find the closest matching resolution among all resolutions available.
Calling Context:
Called to obtain the closest match to a given resolution.
Parameters:
- const TGPoint & resolution -The resolution to be matched.
Return Value:
Returns the closest match to the resolution that can be found for this device.
Exceptions:
Throws no exceptions, passes all exceptions through.
Concurrency:
Not multithread safe.
Other Considerations:
None.
Member Function: TResolution::CreateResolutionRangeIterator
virtual TIteratorOver < TResolutionRange > * CreateResolutionRangeIterator () const
Interface Category:
API.
Purpose:
Creates a resolution range iterator that the client can parse or examine for all the available resolution ranges pertinent to this device.
Calling Context:
Called to create an iterator for all resolutions on this device.
Parameters:
Return Value:
Returns an iterator of resolution ranges.
Exceptions:
Throws no exceptions, passes all exceptions through.
Concurrency:
Not multithread safe.
Other Considerations:
The created iterator is owned by the client who is then responsible for deleting it.
