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.

QStringList KProtocolInfo::capabilities ( const QString &  protocol )

static

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.

Parameters

protocol

the protocol to check

Returns

the list of capabilities.

Definition at line 386 of file kprotocolinfo.cpp.

QString KProtocolInfo::config ( const QString &  protocol )

static

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()

Parameters

protocol

the protocol to check

Returns

the config file, or an empty string if unknown

Definition at line 300 of file kprotocolinfo.cpp.

QString KProtocolInfo::defaultMimeType

(

)

const

. Use KProtocolManager instead.

Definition at line 404 of file kprotocolinfo.cpp.

bool KProtocolInfo::determineMimetypeFromExtension ( const QString &  protocol )

static

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".

Parameters

protocol

the protocol to check

Returns

true if the mime types can be determined by extension

Definition at line 328 of file kprotocolinfo.cpp.

QString KProtocolInfo::docPath ( const QString &  protocol )

static

Returns the documentation path for the specified protocol.

This corresponds to the "X-DocPath=" or "DocPath=" field in the protocol description file.

Parameters

protocol

the protocol to check

Returns

the docpath of the protocol, or an empty string if unknown

Definition at line 359 of file kprotocolinfo.cpp.

QString KProtocolInfo::exec ( const QString &  protocol )

static

Returns the library / executable to open for the protocol protocol Example : "kio_ftp", meaning either the executable "kio_ftp" or the library "kio_ftp.la" (recommended), whichever is available.

This corresponds to the "exec=" field in the protocol description file.

Parameters

protocol

the protocol to check

Returns

the executable of library to open, or QString() for unsupported protocols

KUrl::protocol()

Definition at line 337 of file kprotocolinfo.cpp.

KProtocolInfo::ExtraFieldList KProtocolInfo::extraFields ( const KUrl &  url )

static

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

Definition at line 350 of file kprotocolinfo.cpp.

KProtocolInfo::FileNameUsedForCopying KProtocolInfo::fileNameUsedForCopying ( ) const

protected

Definition at line 439 of file kprotocolinfo.cpp.

QString KProtocolInfo::icon ( const QString &  protocol )

static

Returns the name of the icon, associated with the specified protocol.

This corresponds to the "Icon=" field in the protocol description file.

Parameters

protocol

the protocol to check

Returns

the icon of the protocol, or an empty string if unknown

Definition at line 287 of file kprotocolinfo.cpp.

bool KProtocolInfo::isFilterProtocol ( const KUrl &  url )

static

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.

Parameters

url	the url to check

Returns

true if the protocol is a filter (e.g. gzip), false if the protocol is a helper or source

Definition at line 445 of file kprotocolinfo.cpp.

bool KProtocolInfo::isFilterProtocol ( const QString &  protocol )

static

Same as above except you can supply just the protocol instead of the whole URL.

Definition at line 250 of file kprotocolinfo.cpp.

bool KProtocolInfo::isHelperProtocol ( const KUrl &  url )

static

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).

Parameters

url	the url to check

Returns

true if the protocol is a helper protocol (e.g. vnc), false if not (e.g. http)

Definition at line 450 of file kprotocolinfo.cpp.

bool KProtocolInfo::isHelperProtocol ( const QString &  protocol )

static

Same as above except you can supply just the protocol instead of the whole URL.

Definition at line 455 of file kprotocolinfo.cpp.

bool KProtocolInfo::isKnownProtocol ( const KUrl &  url )

static

Returns whether a protocol is installed that is able to handle url.

Parameters

url	the url to check

Returns

true if the protocol is known

name()

Definition at line 466 of file kprotocolinfo.cpp.

bool KProtocolInfo::isKnownProtocol ( const QString &  protocol )

static

Same as above except you can supply just the protocol instead of the whole URL.

Definition at line 471 of file kprotocolinfo.cpp.

int KProtocolInfo::maxSlaves ( const QString &  protocol )

static

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.

Parameters

protocol

the protocol to check

Returns

the maximum number of slaves, or 1 if unknown

Definition at line 310 of file kprotocolinfo.cpp.

int KProtocolInfo::maxSlavesPerHost ( const QString &  protocol )

static

Returns the limit on the number of slaves for this protocol per host.

This corresponds to the "maxInstancesPerHost=" field in the protocol description file. The default is 0 which means there is no per host limit.

Parameters

protocol

the protocol to check

Returns

the maximum number of slaves, or 1 if unknown

Definition at line 319 of file kprotocolinfo.cpp.

QString KProtocolInfo::protocolClass ( const QString &  protocol )

static

Returns the protocol class for the specified protocol.

This corresponds to the "Class=" field in the protocol description file.

The following classes are defined:

• ":internet" for common internet protocols
• ":local" for protocols that access local resources

Protocol classes always start with a ':' so that they can not be confused with the protocols themselves.

Parameters

protocol

the protocol to check

Returns

the class of the protocol, or an empty string if unknown

Definition at line 368 of file kprotocolinfo.cpp.

QStringList KProtocolInfo::protocols ( )

static

Returns

a list of all known protocols

Definition at line 245 of file kprotocolinfo.cpp.

QString KProtocolInfo::proxiedBy ( const QString &  protocol )

static

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.

Definition at line 395 of file kprotocolinfo.cpp.

bool KProtocolInfo::showFilePreview ( const QString &  protocol )

static

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.

Parameters

protocol

the protocol to check

Returns

true if previews should be shown by default, false otherwise
