Detailed Description

Provides an abstraction for fetching URIs.

It is pluggable through plugins. Each plugin is responsible for one or more URI schemes, but there should be only one plugin associated with each URI scheme. The fetching request will be dispatched to the relevant plugin based on the scheme in the URI.

(

const std::vector< process::Owned< Plugin >> &

Member Function Documentation

process::Future<Nothing> mesos::uri::Fetcher::fetch	(	const URI &	uri,
		const std::string &	directory,
		const Option< std::string > &	data = None(),
		const Option< std::string > &	outputFileName = None()
	)		const

Fetches a URI to the given directory.

This method will dispatch the call to the corresponding plugin based on uri.scheme.

Parameters

uri	the URI to fetch
directory	the directory the URI will be downloaded to
data	the optional user defined data
outputFileName	the optional output file name

process::Future<Nothing> mesos::uri::Fetcher::fetch	(	const URI &	uri,
		const std::string &	directory,
		const std::string &	name,
		const Option< std::string > &	data = None(),
		const Option< std::string > &	outputFileName = None()
	)		const

Fetches a URI to the given directory.

This method will dispatch the call to the plugin chosen by using its name.

Parameters

uri	the URI to fetch
directory	the directory the URI will be downloaded to
name	of the plugin that is used to download
data	the optional user defined data
outputFileName	the optional output file name
