and exports the given local names as properties on the returned object.

This function is used when converting a URI to a file path. Decodes all components of a URI path, with the exception of encoded slash characters, as this would lead to unexpected file locations being targeted (resulting in erroneous behaviour of the file based backend).
The path to decode the URI path components of.
A decoded copy of the provided URI path (ignoring encoded slash characters).
This function is used in the process of converting a file path to a URI. Encodes all (non-slash) special characters in a URI path, with the exception of encoded slash characters, as this would lead to unnecessary double encoding, resulting in a URI that differs from the expected result.
The path to encode the URI path components of.

List of handlers to search in.
The input data.
A promise resolving to a handler that supports the data or otherwise rejecting.
Generates a new HttpError class with the given status code and name. In general, status codes are used to uniquely identify error types, so there should be no 2 classes with the same value there.
To make sure Components.js can work with these newly generated classes,
the generated class should be called BaseHttpError as that name is an entry in .componentsignore.
The actual class should then extend BaseHttpError and have a correct constructor,
so the Components.js generator can generate the correct components JSON-LD file during build.
Returns a URI that is unique for the given status code.
Generates a RedirectHttpErrorClass, similar to how generateHttpErrorClass works.
The difference is that here a location field also gets set and the getInstance method
also uses the RedirectHttpError.isInstance function.

const logger = getLoggerFor('MyFunction');

Makes sure that listeners always receive the error event of a stream, even if it was thrown before the listener was attached.
When guarding a stream it is assumed that error listeners already attached should be ignored, only error listeners attached after the stream is guarded will prevent an error from being logged.
