Class: ComponentLoader

ComponentLoader(reporter, settings)

Component Loader schedules and loads component sources. If no Loading Bases are given it creates 1 Loading Base called "autogen" with location.origin as URL. Scheduling works in 3 steps: - From the desired Buildable Components calculated an ordered list of required Loadable Components - Omit the Loadable Components that are already (being) loaded - Start at the top of the Loadables list and load

Members

(protected) _buildQueue :Array.<BuildRequest>

Queue of BuildableComponents in the order in which they should be loaded/built. By calling the .build() method, components can be added to this queue.

(protected) _concurrentLoadsPerBase :number

Number of files that can be requested simultaneously per loading base. The assumption here is that the maximum number of concurrent loads depends on the browser, not on the host/base and therefore one value suffices, default is 2.
