Kind: instance method of Analyzer

Param Type Description
href string the import to get metadata for.

analyzer.getLoadedAst(href, [loaded]) ⇒ Promise.<DocumentAST>

Returns a promise resolving to a form of the AST with all links replaced with the document they link to. .css and .script files become <style> and <script>, respectively.

Kind: instance method of Analyzer

Param Type Description
predicate Object A dom5 predicate.

analyzer.annotate()

Annotates all loaded metadata with its documentation.

Kind: instance method of Analyzer

analyzer.clean()

Removes redundant properties from the collected descriptors.

Kind: instance method of Analyzer

Analyzer.analyze(href, [options]) ⇒ Promise.<Analyzer>

Shorthand for transitively loading and processing all imports beginning at href.

In order to properly filter paths, href must be an absolute URI.

Kind: static method of Analyzer
Returns: Promise.<Analyzer> - A promise that will resolve once href and its dependencies have been loaded and analyzed.

Param Type Description
href string The root import to begin loading from.
[options] LoadOptions Any additional options for the load.

Kind: static class of hydrolysis

new FileLoader()

A FileLoader lets you resolve URLs with a set of potential resolvers.

fileLoader.addResolver(resolver)

Add an instance of a Resolver class to the list of url resolvers

Ordering of resolvers is most to least recently added The first resolver to "accept" the url wins.

Kind: instance method of FileLoader

Param Type Description

Param Type Description
url string The absolute url to request.
