Detailed Description

The Uri struct provides URI parsing and merging functionality based on RFC 3986.

We have Uri as a struct rather than class to expose member variables. Many ResourceRetreiver classes rewrite URIs to other types of URIs (e.g, resolve 'package://' URIs to 'file://' URIs), which is easier to implement if you have direct access to the URI components.

Constructor & Destructor Documentation

Uri() [1/3]

dart::common::Uri::Uri ( )

default

Constructor.

Uri() [2/3]

dart::common::Uri::Uri

(

const std::string &

_input

)

Constructor that takes a URI or local path.

Internally, this is equivalent to calling fromStringOrPath(_input) after default constructor.

We don't declare this constructor as explicit in order to allow implicit conversion from string so that you can pass in string parameter to a function that takes Uri.

Uri() [3/3]

dart::common::Uri::Uri

(

const char *

_input

)

Constructor that takes a URI or local path as const char*.

The behavior is identical to Uri(const std::string&).

Member Function Documentation

clear()

void dart::common::Uri::clear

(

)

Clear the URI by reset()ing all components.

createFromPath()

Uri dart::common::Uri::createFromPath ( const std::string &  _path )

static

Create file URI from a string; return an empty URI on failure.

createFromRelativeUri() [1/3]

Uri dart::common::Uri::createFromRelativeUri ( const std::string &  _base, const std::string &  _relative, bool  _strict = false  )

static

Create URI resolving a relative path reference; return an empty URI on failure.

createFromRelativeUri() [2/3]

Uri dart::common::Uri::createFromRelativeUri ( const Uri &  _base, const std::string &  _relative, bool  _strict = false  )

static

Create URI resolving a relative path reference; return an empty URI on failure.

createFromRelativeUri() [3/3]

Uri dart::common::Uri::createFromRelativeUri ( const Uri &  _base, const Uri &  _relative, bool  _strict = false  )

static

Create URI resolving a relative path reference; return an empty URI on failure.

createFromString()

Uri dart::common::Uri::createFromString ( const std::string &  _input )

static

Create URI from a string; return an empty URI on failure.

createFromStringOrPath()

Uri dart::common::Uri::createFromStringOrPath ( const std::string &  _input )

static

Create general URI or file URI from a string; return an empty URI on failure.

fromPath()

bool dart::common::Uri::fromPath

(

const std::string &

_path

)

Parse a local path (i.e.

URI with no schema) from a string; return success. Note that the input path should be absolute path. All the components will be cleared on failure.

fromRelativeUri() [1/5]

bool dart::common::Uri::fromRelativeUri	(	const char *	_base,
		const char *	_relative,
		bool	_strict = false
	)

Resolve a relative path reference; return success.

All the components will be cleared on failure.

fromRelativeUri() [2/5]

bool dart::common::Uri::fromRelativeUri	(	const std::string &	_base,
		const std::string &	_relative,
		bool	_strict = false
	)

Resolve a relative path reference; return success.

All the components will be cleared on failure.

fromRelativeUri() [3/5]

bool dart::common::Uri::fromRelativeUri	(	const Uri &	_base,
		const char *	_relative,
		bool	_strict = false
	)

Resolve a relative path reference; return success.

All the components will be cleared on failure.

fromRelativeUri() [4/5]

bool dart::common::Uri::fromRelativeUri	(	const Uri &	_base,
		const std::string &	_relative,
		bool	_strict = false
	)

Resolve a relative path reference; return success.

All the components will be cleared on failure.

fromRelativeUri() [5/5]

bool dart::common::Uri::fromRelativeUri	(	const Uri &	_base,
		const Uri &	_relative,
		bool	_strict = false
	)

Resolve a relative path reference; return success.

All the components will be cleared on failure.

fromString()

bool dart::common::Uri::fromString

(

const std::string &

_input

)

Parse a URI from a string; return success.

All the components will be cleared on failure.

fromStringOrPath()

bool dart::common::Uri::fromStringOrPath

(

const std::string &

_input

)

Parse a URI or local path (i.e.

URI with no schema) from a string; return success. We assume that any string without a scheme is a path. All the components will be cleared on failure.

getFilesystemPath()

std::string dart::common::Uri::getFilesystemPath

(

)

const

Get the path in the local filesystem as a string.

You should use this function rather than getPath() if you are trying to access a local file. Note that this function is identical to getPath() for Unix systems, but differ by the leading '/' on Windows.

getPath()

std::string dart::common::Uri::getPath

(

)

const

Get the path component of the URI as a string.

getRelativeUri() [1/3]

std::string dart::common::Uri::getRelativeUri ( const std::string &  _base, const std::string &  _relative, bool  _strict = false  )

static

Resolve a relative path reference; return an empty string on failure.

getRelativeUri() [2/3]

std::string dart::common::Uri::getRelativeUri ( const Uri &  _base, const std::string &  _relative, bool  _strict = false  )

static

Resolve a relative path reference; return an empty string on failure.

getRelativeUri() [3/3]

std::string dart::common::Uri::getRelativeUri ( const Uri &  _base, const Uri &  _relative, bool  _strict = false  )

static

Resolve a relative path reference; return an empty string on failure.

getUri()

std::string dart::common::Uri::getUri ( const std::string &  _input )

static

Parse a URI from a string; return an empty string on failure.

mergePaths()

std::string dart::common::Uri::mergePaths ( const Uri &  _base, const Uri &  _relative  )

staticprivate

Implement section 5.2.3 of RFC 3986.

removeDotSegments()

std::string dart::common::Uri::removeDotSegments ( const std::string &  _path )

staticprivate

Implement section 5.2.4 of RFC 3986.

toString()

std::string dart::common::Uri::toString

(

)

const

Combine the parts of the URI into a string.
