Constructor Details

#initialize(paths: [], filters: []) ⇒ CachedAssetFile

For each of the given paths, recursively reads each asset and stores its contents alongside the full path to the asset.

paths - One or more String representing directories on disk to search

for asset files. Note: paths are searched recursively.

filters - One or more Strings/Regexps to match assets against. Only

assets matching all filters will be cached and available to load.
Note: Specifying no filters will cache every file found in
paths.
