Detailed Description
Information about I/O (Internet, etc.) protocols supported by KDE.
This class is useful if you want to know which protocols KDE supports. In addition you can find out lots of information about a certain protocol. A KProtocolInfo instance represents a single protocol. Most of the functionality is provided by the static methods that scan the *.protocol files of all installed kioslaves to get this information.
*.protocol files are installed in the "services" resource.

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).
Definition at line 60 of file kprotocolinfo.cpp. References findProtocol(), and T_NONE. |
|
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.
Definition at line 130 of file kprotocolinfo.cpp. References findProtocol(). |
|
Definition of extra fields in the UDS entries, returned by a listDir operation. This corresponds to the "ExtraNames=" and "ExtraTypes=" fields in the protocol description file. Those two lists should be separated with ',' in the protocol description file. See ExtraField for details about names and types
|
|
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.
Definition at line 70 of file kprotocolinfo.cpp. References findProtocol(). |
|
Returns whether the protocol can act as a helper protocol. A helper protocol invokes an external application and does not return a file or stream. This corresponds to the "helper=" field in the protocol description file. Valid values for this field are "true" or "false" (default).
Definition at line 94 of file kprotocolinfo.cpp. References KURL::protocol(). Referenced by KRun::init(), and KRun::processDesktopExec(). |
|
Same as above except you can supply just the protocol instead of the whole URL.
Definition at line 99 of file kprotocolinfo.cpp. |
|
Returns whether the protocol can act as a filter protocol. A filter protocol can operate on data that is passed to it but does not retrieve/store data itself, like gzip. A filter protocol is the opposite of a source protocol. The "source=" field in the protocol description file determines whether a protocol is a source protocol or a filter protocol. Valid values for this field are "true" (default) for source protocol or "false" for filter protocol.
Definition at line 79 of file kprotocolinfo.cpp. References KURL::protocol(). |
|
Same as above except you can supply just the protocol instead of the whole URL.
Definition at line 84 of file kprotocolinfo.cpp. |
|
Returns whether the protocol can list files/objects. If a protocol supports listing it can be browsed in e.g. file-dialogs and konqueror. Whether a protocol supports listing is determined by the "listing=" field in the protocol description file. If the protocol support listing it should list the fields it provides in this field. If the protocol does not support listing this field should remain empty (default.)

Returns whether the protocol can create directories/folders. This corresponds to the "makedir=" field in the protocol description file. Valid values for this field are "true" or "false" (default).
Definition at line 157 of file kprotocolinfo.cpp. References findProtocol(). |
|
Returns whether the protocol can delete files/objects. This corresponds to the "deleting=" field in the protocol description file. Valid values for this field are "true" or "false" (default).
Definition at line 166 of file kprotocolinfo.cpp. References findProtocol(). |
|
Returns whether the protocol can create links between files/objects. This corresponds to the "linking=" field in the protocol description file. Valid values for this field are "true" or "false" (default).
Definition at line 175 of file kprotocolinfo.cpp. References findProtocol(). |
|
Returns whether the protocol can move files/objects between different locations. This corresponds to the "moving=" field in the protocol description file. Valid values for this field are "true" or "false" (default).
Definition at line 184 of file kprotocolinfo.cpp. References findProtocol(). |
|
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).
Definition at line 193 of file kprotocolinfo.cpp. References findProtocol(). |
|
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).
Definition at line 203 of file kprotocolinfo.cpp. References findProtocol(). |
|
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).
Definition at line 212 of file kprotocolinfo.cpp. References canRenameFromFile(), and findProtocol(). Referenced by canRenameFromFile(). |
|
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).
Definition at line 222 of file kprotocolinfo.cpp. References canRenameToFile(), and findProtocol(). Referenced by canRenameToFile(). |
|
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).
Definition at line 231 of file kprotocolinfo.cpp. References canDeleteRecursive(), and findProtocol(). Referenced by canDeleteRecursive(). |
|
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).
Definition at line 240 of file kprotocolinfo.cpp. References fileNameUsedForCopying(), and findProtocol(). Referenced by fileNameUsedForCopying(). |
|
Returns default mimetype for this URL based on the protocol. This corresponds to the "defaultMimetype=" field in the protocol description file.
Definition at line 249 of file kprotocolinfo.cpp. References findProtocol(). Referenced by KMimeType::findByURL(), and KRun::init(). |
|
Returns the name of the icon, associated with the specified protocol. This corresponds to the "Icon=" field in the protocol description file.
Referenced by KMimeType::iconForURL(), and KFileSpeedBar::KFileSpeedBar(). |
|
Returns the name of the config file associated with the specified protocol. This is useful if two similar protocols need to share a single config file, e.g. http and https. This corresponds to the "config=" field in the protocol description file. The default is the protocol name, see name()
|
|
Returns the soft limit on the number of slaves for this protocol. This limits the number of slaves used for a single operation, note that multiple operations may result in a number of instances that exceeds this soft limit. This corresponds to the "maxInstances=" field in the protocol description file. The default is 1.
|
|
Returns whether mimetypes can be determined based on extension for this protocol. For some protocols, e.g. http, the filename extension in the URL can not be trusted to truly reflect the file type. This corresponds to the "determineMimetypeFromExtension=" field in the protocol description file. Valid values for this field are "true" (default) or "false".
Referenced by KMimeType::findByURL(). |
|
Returns the documentation path for the specified protocol. This corresponds to the "DocPath=" field in the protocol description file.
|
|
Returns the protocol class for the specified protocol. This corresponds to the "Class=" field in the protocol description file. The following classes are defined:
Referenced by KIO::ForwardingSlaveBase::prepareUDSEntry(). |
|
Returns whether file previews should be shown for the specified protocol. This corresponds to the "ShowPreviews=" field in the protocol description file. By default previews are shown if protocolClass is :local.
|
|
Returns the suggested URI parsing mode for the KURL parser. This corresponds to the "URIMode=" field in the protocol description file. The following parsing modes are defined:
|
|
Returns the list of capabilities provided by the kioslave implementing this protocol. This corresponds to the "Capabilities=" field in the protocol description file. The capability names are not defined globally, they are up to each slave implementation. For example when adding support for a new special command for mounting, one would add the string "Mount" to the capabilities list, and applications could check for that string before sending a special() command that would otherwise do nothing on older kioslave implementations.
|
|
Returns the name of the protocol through which the request will be routed if proxy support is enabled. A good example of this is the ftp protocol for which proxy support is commonly handled by the http protocol. This corresponds to the "ProxiedBy=" in the protocol description file.
