Detailed Description
Manages the 'reduced' cached buffer dataset associated with a CCE worldtube and interpolates to requested time points to provide worldtube boundary data to the main evolution routines.
Details
The maintained buffer will be kept at a length that is set by the Interpolator and the buffer_depth also passed to the constructor. A longer depth will ensure that the buffer updater is called less frequently, which is useful for slow updaters (e.g. those that perform file access). The main functionality is provided by the WorldtubeDataManager::populate_hypersurface_boundary_data() member function that handles buffer updating and boundary computation. This version of the data manager handles the 9 scalars of cce_bondi_input_tags, rather than direct metric components handled by WorldtubeDataManager. The set of 9 scalars is a far leaner (factor of ~4) data storage format.

Update the boundary_data_box entries for all tags in Tags::characteristic_worldtube_boundary_tags to the boundary data at time.
Details
First, if the stored buffer requires updating, it will be updated via the buffer_updater_ supplied in the constructor. Then, each of the 9 spin-weighted scalars in cce_bondi_input_tags are interpolated across buffer points to the requested time value (via the Interpolator provided in the constructor). Finally, the remaining two scalars not directly supplied in the input file are calculated in-line and put in the DataBox.
Returns true if the time can be supplied from the buffer_updater_, and false otherwise. No tags are updated if false is returned.
