| MAXON_METHOD const UrlScheme& GetScheme | ( | ) | const |
Gets the UrlScheme of the Url. Is guarantueed to be lowercase (canonical form for urls) if scheme was automatically determined through SetUrl, otherwise as set.
Urls consist of three parts: a scheme, an authority and a path. The readable text-representation is "scheme://authority/path".
The scheme defines which handler is used, e.g. "http" for web-based connections or "file" for the regular file system.
The authority defines the machine, which can be empty for "localhost", a network drive or a webserver. It can also refer to an embedded file, e.g. a ZIP. To distinguish that case the readable text representation contains brackets: "scheme://[authority]/path". Nesting is possible repeatedly.
Finally the path component defines the unique location of a file or directory on the target machine. In most schemes paths are a combination of the directory path and file path, but the path could also be a network query or database entry. Path components are always separated by a forward slash and the forward slash is a reserved character that cannot be used for names.
| MAXON_METHOD Result<void> SetScheme | ( | const UrlScheme & | scheme | ) |
Sets the scheme of the Url. Path and authority will stay unchanged.

| [in] | scheme | The new scheme UrlScheme Id e.g. URLSCHEME_FILESYSTEM, URLSCHEME_ZIPFILE or URLSCHEME_MEMORY. Should always be lowercase because no normalization is applied here. |
| MAXON_METHOD Result<void> Append | ( | const String & | name | ) |
Appends a new component to the Url. E.g. if the Url is "file:///c:/directory" a call of Append("file.txt"_s) will result in "file:///c:/directory/file.txt".
| [in] | name | A component that will be added to the end of the Url. A separator (forward slash) will be placed between the end of the current Url and the new part. The value must not contain any forward slashes (under Windows additionally no backslashes), otherwise nothing will be done. |
@MAXON_ANNOTATION{returnsThis,noResult}
| MAXON_METHOD Result<void> Append | ( | const Url & | relativeUrl | ) |
Appends a relative Url to the current one. E.g. if the Url is "file:///c:/directory" a call of Append(Url("test/file.txt"_s)) will result in "file:///c:/directory/test/file.txt".
| [in] | relativeUrl | The relative Url that will be added. A separator (forward slash) will be placed between the end of the current Url and the new part. relativeUrl must be a Url with URLSCHEME_RELATIVE, otherwise nothing will be done. |
@MAXON_ANNOTATION{returnsThis,noResult}
| MAXON_METHOD Result<void> RemoveName | ( | ) |
Removes the last part of a Url. E.g. if the Url is "file:///c:/directory/file.txt" a call of RemoveName() will result in "file:///c:/directory".
| MAXON_METHOD Url GetEmbeddedUrl | ( | ) | const |
Returns an embedded Url. E.g. if the Url is "zip://[file:///c:/images.zip]/image01.jpg" a call to GetEmbeddedUrl() will return "file:///c:/images.zip".
| MAXON_METHOD Result<void> SetEmbeddedUrl | ( | const Url & | url | ) |
| MAXON_METHOD String GetName | ( | ) | const |
| MAXON_METHOD Result<void> SetName | ( | const String & | name | ) |
Replaces the last component of a Url. The name must not contain a forward slashes and under Windows additionally no backslashes. E.g. if the Url is "file:///c:/directory/file.txt" a call of SetName("change.tif"_s) will result in "file:///c:/directory/change.tif".
| [in] | name | The new name. |
| MAXON_METHOD Url GetDirectory | ( | ) | const |
Returns the Url of the directory. If the Url is empty the directory is empty as well. E.g. if the Url was "file:///c:/directory/file.txt" a call of GetDirectory() will return "file:///c:/directory".
| MAXON_METHOD Result<void> SetPath | ( | const String & | path | ) |
Replaces the path component of the Url. The path is stored unchanged with the exception that under Windows all backslashes will be changed into forward slashes.
| [in] | path | The new path. |
| MAXON_METHOD Result<void> SetPath | ( | const String & | path, |
| Bool | convertWindowsBackslashes | ||
| ) |
Replaces the path component of the Url. The path is stored unchanged with the exception that under Windows all backslashes will be changed into forward slashes.
| [in] | path | The new path. |
| [in] | convertWindowsBackslashes | True to convert backslashes under windows. |
| MAXON_METHOD const String& GetPath | ( | ) | const |
| MAXON_METHOD Result<void> SetSystemPath | ( | const String & | path | ) |
Stores a system path in a Url. This call needs to be done after the appropriate scheme has been set. If no scheme is set URLSCHEME_FILESYSTEM will be automatically set. The system path may be converted to a different internal representation, e.g. split into authority and path components. Under Windows all backslashes will be changed into forward slashes.
| [in] | path | The system path. |
| MAXON_METHOD Result<String> GetSystemPath | ( | ) | const |
Returns a path from the Url that the current operating system (or scheme handler) can understand. If the Url contains no valid scheme an error will be returned. An error will also be returned if the Url contains illegal characters for the scheme, e.g. backslashes on Windows in a file scheme.
| MAXON_METHOD Result<void> SetUrl | ( | const String & | urlString, |
| Bool | enableDefaultFallbackScheme | ||
| ) |
Sets the Url. The scheme is detected automatically and converted to the canonical lowercase version (as described in rfc3986#3.1). If a scheme isn't found and enableDefaultFallbackScheme is false the function returns an IllegalArgumentError, otherwise URLSCHEME_FILESYSTEM will be assumed (or URLSCHEME_RELATIVE if 'urlString' starts with no drive letter). Please note that Urls only use forward slashes as delimiter, backslashes are considered to be a part of names and not a delimiter. '?' will be considered as the start of URLFLAGS::QUERY parameters. Everything behin the '?' will be placed in that property. Use url.Get(URLFLAGS::QUERY) to get the query parameters.
| [in] | urlString | The new Url to be set. |
| [in] | enableDefaultFallbackScheme | If false and no scheme is set an error will be returned. |

| MAXON_METHOD const Url& GetAuthority | ( | ) | const |
| MAXON_METHOD Result<void> GetComponents | ( | const NonConstArray< String > & | parts | ) | const |
Returns all parts of the Url system path as separated strings. E.g. if the Url was "file:///c:/directory/file.txt" a call of GetComponents will return: { "C:", "directory", "file.txt" }.
| [out] | parts | Array with the parts of the system path. A possible authority will be returned as the first part of the array. |
| MAXON_METHOD Result<Url> GetRelativeUrl | ( | const Url & | basePath | ) | const |
Returns a relative url based on the given basePath. The basePath needs to have the same scheme, authority. basepath needs to be part of the path of this url.
| [in] | basePath | The base of the relative url. |
| MAXON_METHOD String GetSuffix | ( | ) | const |
Returns the suffix of the Url. E.g. if the Url was "file:///c:/directory/file.txt" a call of GetSuffix() will return "txt".
| MAXON_METHOD Bool CheckSuffix | ( | const String & | suffix | ) | const |
| MAXON_METHOD Result<void> SetSuffix | ( | const String & | suffix | ) |
Replaces the suffix of the Url. If the Url had no suffix before a dot will be added together with the suffix string. E.g. if the Url is "file:///c:/directory/file.txt" a call of SetSuffix("jpg"_s) will result in "file:///c:/directory/file.jpg".
| [in] | suffix | The new suffix of the Url without dot. |

| [in] | recursive | Recursively deletes a directory and its content. If a file is specified this value is ignored. |
| MAXON_FUNCTION Result<void> IoCreateDirectory | ( | Bool | createParents, |
