initialise to blank (zero).

You need at least to set the framerate, in order to create a usable TimeGrid

lib::P< TimeGrid > commit ( )

create a time grid based on settings within this builder

Setup of a TimeGrid: validate the settings configured into this builder instance, then decide on the implementation strategy for the time grid.

Convert the given frames per second into an appropriate gridSpacing time and build a suitable name-ID to denote the TimeGrid-meta-Asset to be built.

Returns: shared_ptr holding onto the new asset::Meta, which has already been registered with the AssetManager.

Exceptions

error::Config in case of invalid frames-per-second. The AssetManager might raise further exception when asset registration fails.

Note: the newly created grid is automatically published through the Advice System. This allows client code to pick up that grid definition just by using the Grid ID, without requiring an explicit link to the session or Asset subsystem.

Todo:: currently (12/2010) the AssetManager is unable to detect duplicate assets. Later on the intention is that in such cases, instead of creating a new grid we'll silently return the already registered existing and equivalent grid.
