What's the type of "m_meshCollection" in "Spatial mapping in DirectX"?

I am following the tutorial "Spatial mapping in DirectX (https://developer.microsoft.com/en-us/windows/holographic/spatial_mapping_in_directx)" but am stucking here:

Initialize and update the surface mesh collection
If the surface observer was successfully created, we can proceed to initialize our surface mesh collection. Here we use the pull model API to get the current set of observed surfaces right away:

auto mapContainingSurfaceCollection = m_surfaceObserver->GetObservedSurfaces();
for (auto& pair : mapContainingSurfaceCollection)
// Store the ID and metadata for each surface.
auto const& id = pair->Key;
auto const& surfaceInfo = pair->Value;
m_meshCollection->AddOrUpdateSurface(id, surfaceInfo);

What's the definition of m_meshCollection and how it was initialized?
