		const PlotMSTransformations &	transformations,
		PlotMSCacheThread *	thread = `NULL`
	)		`[virtual]`

Loads the cache for the given axes and data columns.

IMPORTANT: this method assumes that any currently loaded data is valid for the given VisIter; i.e., if the meta-information or either of the axes are already loaded, then they don't need to be reloaded. If this is not the case, then clear() should be called BEFORE append(). If a PlotMSCacheThreadHelper object is given, it will be used to report progress information.

void casa::PlotCalCache::loadCalAxis	(	Table &	tab,
		Int	vbnum,
		PMS::Axis	axis
	)		`[private]`

Loads the specific axis/metadata into the cache using the given VisBuffer.

		const vector< PMS::DataColumn >	loadData,
		PlotMSCacheThread *	thread
