class aria.parser.loading.LoaderSource

Bases: object

Base class for ARIA loader sources.

Loader sources provide appropriate Loader instances for locations.

get_loader(context, location, origin_location)
class aria.parser.loading.DefaultLoaderSource

Bases: aria.parser.loading.source.LoaderSource

The default ARIA loader source will generate a UriTextLoader for UriLocation and a LiteralLoader for a LiteralLocation.

get_loader(context, location, origin_location)
class aria.parser.loading.Location

Bases: object

Base class for ARIA locations.

Locations are used by LoaderSource to delegate to an appropriate Loader.

is_equivalent(location)
prefix
class aria.parser.loading.UriLocation(uri)

Bases: aria.parser.loading.location.Location

A URI location can be absolute or relative, and can include a scheme or not.

If no scheme is included, it should be treated as a filesystem path.

See UriTextLoader.

is_equivalent(location)
prefix
class aria.parser.loading.LiteralLocation(content, name=’literal’)

Bases: aria.parser.loading.location.Location

A location that embeds content.

See LiteralLoader.

is_equivalent(location)
class aria.parser.loading.LiteralLoader(location)

Bases: aria.parser.loading.loader.Loader

ARIA literal loader.

See LiteralLocation.

load()
class aria.parser.loading.UriTextLoader(context, location, origin_location=None)

Bases: aria.parser.loading.loader.Loader

Base class for ARIA URI loaders.

See UriLocation.

Supports a list of search prefixes that are tried in order if the URI cannot be found. They will be:

  • If origin_location is provided its prefix will come first.
  • Then the prefixes in the LoadingContext will be added.
  • Finally, the parser can supply a uri_loader_prefix function with extra prefixes.

Bases: aria.parser.loading.loader.Loader

Base class for ARIA request-based loaders.

class aria.parser.loading.RequestTextLoader(context, uri, headers=None)

Bases: aria.parser.loading.request.RequestLoader

ARIA request-based text loader.

load()
class aria.parser.loading.FileTextLoader(context, path, encoding=’utf-8’)

Bases: aria.parser.loading.loader.Loader

ARIA file text loader.
