QString acceptLanguagesHeader | ( |  | ) |

Return Accept-Languages header built up according to user's desktop language settings.

Returns:
  Accept-Languages header string

bool autoResume | ( |  | ) |

Returns true if partial downloads should be automatically resumed.

Returns:
  true to resume partial downloads

badProxy | ( | QString | proxy
| ) |  |  |

Marks this proxy as bad (down). It will not be used for the next 30 minutes. (The script may supply an alternate proxy)

Parameters:

  | proxy | the proxy to mark as bad (as URL)

KIO.CacheControl cacheControl | ( |  | ) |

Returns the Cache control directive to be used.

Returns:
  the cache control value

QString cacheDir | ( |  | ) |

The directory which contains the cache files.

Returns:
  the directory that contains the cache files

bool canCopyFromFile | ( | KUrl | url
| ) |  |  |

Returns whether the protocol can copy files/objects directly from the filesystem itself. If not, the application will read files from the filesystem using the file-protocol and pass the data on to the destination protocol.

This corresponds to the "copyFromFile=" field in the protocol description file. Valid values for this field are "true" or "false" (default).

Parameters:

  | url | the url to check

Returns:
  true if the protocol can copy files from the local file system

bool canCopyToFile | ( | KUrl | url
| ) |  |  |

Returns whether the protocol can copy files/objects directly to the filesystem itself. If not, the application will receive the data from the source protocol and store it in the filesystem using the file-protocol.

This corresponds to the "copyToFile=" field in the protocol description file. Valid values for this field are "true" or "false" (default).

Parameters:

  | url | the url to check

Returns:
  true if the protocol can copy files to the local file system

bool canDeleteRecursive | ( | KUrl | url
| ) |  |  |

Returns whether the protocol can recursively delete directories by itself. If not (the usual case) then KIO will list the directory and delete files and empty directories one by one.

This corresponds to the "deleteRecursive=" field in the protocol description file. Valid values for this field are "true" or "false" (default).

Parameters:

  | url | the url to check

Returns:
  true if the protocol can delete non-empty directories by itself.

bool canRenameFromFile | ( | KUrl | url
| ) |  |  |

Returns whether the protocol can rename (i.e. move fast) files/objects directly from the filesystem itself. If not, the application will read files from the filesystem using the file-protocol and pass the data on to the destination protocol.

This corresponds to the "renameFromFile=" field in the protocol description file. Valid values for this field are "true" or "false" (default).

Parameters:

  | url | the url to check

Returns:
  true if the protocol can rename/move files from the local file system

bool canRenameToFile | ( | KUrl | url
| ) |  |  |

Returns whether the protocol can rename (i.e. move fast) files/objects directly to the filesystem itself. If not, the application will receive the data from the source protocol and store it in the filesystem using the file-protocol.

This corresponds to the "renameToFile=" field in the protocol description file. Valid values for this field are "true" or "false" (default).

Parameters:

  | url | the url to check

Returns:
  true if the protocol can rename files to the local file system

int connectTimeout | ( |  | ) |

Returns the preferred timeout value for remote connections in seconds.

Returns:
  timeout value for remote connection in secs.

QString defaultMimetype | ( | KUrl | url
| ) |  |  |

Returns:
  the default mime type of the protocol, or null if unknown

QString defaultUserAgent | ( |  | ) |

Returns the default user-agent string used for web browsing.

Returns:
  the default user-agent string

QString defaultUserAgent | ( | QString | keys
| ) |  |  |

Parameters:

  | keys | can be any of the following:

- 'o' Show OS
- 'v' Show OS Version
- 'p' Show platform (only for X11)
- 'm' Show machine architecture
- 'l' Show language

Returns:
  the default user-agent value with the given keys

KProtocolInfo.FileNameUsedForCopying fileNameUsedForCopying | ( | KUrl | url
| ) |  |  |

This setting defines the strategy to use for generating a filename, when copying a file or directory to another directory. By default the destination filename is made out of the filename in the source URL. However if the ioslave displays names that are different from the filename of the URL (e.g. kio_fonts shows Arial for arial.ttf, or kio_trash shows foo.txt and uses some internal URL), using Name means that the display name (UDS_NAME) will be used to as the filename in the destination directory.

This corresponds to the "fileNameUsedForCopying=" field in the protocol description file. Valid values for this field are "Name" or "FromURL" (default).

Parameters:

  | url | the url to check

Returns:
  how to generate the filename in the destination directory when copying/moving

bool getSystemNameVersionAndMachine | ( | QString | systemName,
|  | QString | systemVersion,
|  | QString | machine

KProtocolInfo.Type inputType | ( | KUrl | url
| ) |  |  |

Returns whether the protocol should be treated as a filesystem or as a stream when reading from it.

This corresponds to the "input=" field in the protocol description file. Valid values for this field are "filesystem", "stream" or "none" (default).

Parameters:

  | url | the url to check

Returns:
  the input type of the given url

bool isSourceProtocol | ( | KUrl | url
| ) |  |  |

Returns whether the protocol can act as a source protocol.

A source protocol retrieves data from or stores data to the location specified by a URL. A source protocol is the opposite of a filter protocol.

The "source=" field in the protocol description file determines whether a protocol is a source protocol or a filter protocol.

Parameters:

  | url | the url to check

Returns:
  true if the protocol is a source of data (e.g. http), false if the protocol is a filter (e.g. gzip)

Returns the list of fields this protocol returns when listing The current possibilities are Name, Type, Size, Date, AccessDate, Access, Owner, Group, Link, URL, MimeType as well as Extra1, Extra2 etc. for extra fields (see extraFields).

This corresponds to the "listing=" field in the protocol description file. The supported fields should be separated with ',' in the protocol description file.

Parameters:

Returns:
  a list of field names

By default this function returns the DEFAULT_MAX_CACHE_SIZE value as defined in http_slave_defaults.h. Not that the value returned is in bytes, hence a value of 5120 would mean 5 Kb.

Returns:
  the maximum cache size in bytes

int minimumKeepSize | ( |  | ) |

Returns the minimum file size for keeping aborted downloads.

Any data downloaded that does not meet this minimum requirement will simply be discarded. The default size is 5 KB.

Returns the strings for hosts that should contacted DIRECTLY, bypassing any proxy settings.

Returns:
  a list of (comma-separated) hostnames or partial host names

KProtocolInfo.Type outputType | ( | KUrl | url
| ) |  |  |

Returns whether the protocol should be treated as a filesystem or as a stream when writing to it.

This corresponds to the "output=" field in the protocol description file. Valid values for this field are "filesystem", "stream" or "none" (default).

Parameters:

  | url | the url to check

Returns:
