Method Detail

• static void addCacheDependency(String fileName, AssetFile dependentFile)

  Called during asset processing to add a dependent file to another file cache. This allows for cache busting on things like imported less files or sass files.

  Parameters:

  fileName - The name of the file we are adding a dependency to

  dependentFile - the AssetFile object we are adding as a dependency

• static void asyncCacheSave()

  Asynchronously starts a thread used to persist the cache to disk It also performs a debounce behavior so rapid calls to the save do not cause repeat saves

• static void createCache(String fileName, String md5Hash, String processedFileText, String originalFileName = null)

  Creates a cache entry for a file. This includes a name, md5Hash and processed file text

  Parameters:

  fileName - The file name of the file to be cached (cache key)

  md5Hash - The current md5 hash of the file

  processedFileText - The processed text of the file being cached

  originalFileName - The original file name of the base file being persisted

• static String findCache(String fileName, String md5, String originalFileName = null)

  Returns the cache string value of a file if it exists in the cache and is unmodified since last checked

  Returns:

  A String value of the cache

  Parameters:

  fileName - The name of the file also known as the cache key

  md5 - The current md5 digest of the file. This is compared against the original file

  originalFileName - - Original file name of the file. This is for cache busting bundled assets

• static void loadPersistedCache()

  Loads an Asset Cache dependency graph for asset-pipeline. This is currently encoded in JSON If the asset cache file does not exist or a cache is already loaded, the cache store is not parsed.

• static void save()

  Called by the async CachePersister class to save the cache map to disk
