KProtocolInfo Class Reference

from PyKDE4.kdecore import *

Detailed Description

\class KProtocolInfo kprotocolinfo.h <KProtocolInfo>

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.

Method Documentation

__init__	(	self,
		QDataStream	_str,
		int	offset
	)

Internal:: construct a KProtocolInfo from a stream

__init__	(	self,
		QString	path
	)

Read a protocol description file

Parameters:

path

the path of the description file

QStringList archiveMimeTypes ( self )

@internal. Use KProtocolManager instead.

bool canDeleteRecursive ( self )

bool canRenameFromFile ( self )

bool canRenameToFile ( self )

QStringList capabilities	(	QString	protocol
	)

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.

QString config	(	QString	protocol
	)

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

QString defaultMimeType ( self )

@internal. Use KProtocolManager instead.

bool determineMimetypeFromExtension	(	QString	protocol
	)

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

QString docPath	(	QString	protocol
	)

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

QString exec_	(	QString	protocol
	)

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

See also:: KUrl.protocol()

KProtocolInfo.ExtraFieldList extraFields	(	KUrl	url
	)

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

KProtocolInfo.FileNameUsedForCopying fileNameUsedForCopying ( self )

QString icon	(	QString	protocol
	)

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

bool isFilterProtocol	(	KUrl	url
	)

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

bool isFilterProtocol	(	QString	protocol
	)

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

bool isHelperProtocol	(	KUrl	url
	)

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)

bool isHelperProtocol	(	QString	protocol
	)

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

bool isKnownProtocol	(	KUrl	url
	)

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

See also:: name()

bool isKnownProtocol	(	QString	protocol
	)

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

int maxSlaves	(	QString	protocol
	)

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

QString protocolClass	(	QString	protocol
	)

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

QStringList protocols ( )

Returns list of all known protocols.

Returns:: a list of all known protocols

QString proxiedBy	(	QString	protocol
	)

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.

bool showFilePreview	(	QString	protocol
	)

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

bool supportsListing ( self )

@internal. Use KProtocolManager instead.
