Attributes

cache  [R]  Get persistent cache store

Public Instance methods

[](*args)

Preferred `find_asset` shorthand. 

    environment['application.js']
attributes_for(path)

Internal. Return a `AssetAttributes` for `path`.

cache=(cache)

Set persistent cache store

The cache store must implement a pair of getters and setters. Either `get(key)`/`set(key, value)`, `[key]`/`[key]=value`, `read(key)`/`write(key, value)`.

content_type_of(path)

Internal. Return content type of `path`.

entries(pathname)

Works like `Dir.entries`.

Subclasses may cache this method.

file_digest(path, data = nil)

Read and compute digest of filename.

Subclasses may cache this method.

find_asset(path, options = {})

Find asset by logical path or expanded path.

index()

Return an `Index`. Must be implemented by the subclass.

stat(path)

Works like `File.stat`.

Subclasses may cache this method.

Protected Instance methods

expire_index!()

Clear index after mutating state. Must be implemented by the subclass.
