Detailed Description

There are two classes that specifies the protocol between application (job) and kioslave.

SlaveInterface is the class to use on the application end, SlaveBase is the one to use on the slave end.

Slave implementations should simply inherit SlaveBase

A call to foo() results in a call to slotFoo() on the other end.

Definition at line 44 of file slavebase.h.


Member Function Documentation

void SlaveBase::data const QByteArray   data
 

Sends data in the slave to the job (i.e.

in get).

To signal end of data, simply send an empty QByteArray().

Parameters:
data  the data read by the slave

void SlaveBase::dataReq  
 

Asks for data from the job.

References canResume(), and KIO::Connection::send().

void SlaveBase::error int    _errid,
const QString   _text
 

Call to signal an error.

This also finishes the job, no need to call finished.

If the Error code is KIO::ERR_SLAVE_DEFINED then the _text should contain the complete translated text of of the error message. This message will be displayed in an KTextBrowser which allows rich text complete with hyper links. Email links will call the default mailer, "exec:/command arg1 arg2" will be forked and all other links will call the default browser.

KIO::Error , KTextBrowser
Parameters:
_errid  the error code from KIO::Error
_text  the rich text error message

void SlaveBase::slaveStatus const QString   host,
bool    connected
 

Used to report the status of the slave.

Parameters:
host  the slave is currently connected to. (Should be empty if not connected)
connected  Whether an actual network connection exists.

void SlaveBase::statEntry const UDSEntry   _entry
 

Call this from stat() to express details about an object, the UDSEntry customarily contains the atoms describing file name, size, mimetype, etc.

Parameters:
_entry  The UDSEntry containing all of the object attributes.

bool SlaveBase::canResume KIO::filesize_t    offset
 

Call this at the beginning of put(), to give the size of the existing partial file, if there is one.

The offset argument notifies the other job (the one that gets the data) about the offset to use. In this case, the boolean returns whether we can indeed resume or not (we can't if the protocol doing the get() doesn't support setting an offset)

References data(), and KIO::Connection::send().

void SlaveBase::processedSize KIO::filesize_t    _bytes

void SlaveBase::openConnection   [virtual]
 

Opens the connection (forced) When this function gets called the slave is operating in connection-oriented mode.

When a connection gets lost while the slave operates in connection oriented mode, the slave should report ERR_CONNECTION_BROKEN instead of reconnecting. The user is expected to disconnect the slave in the error handler.

When the slave was operating in connection-oriented mode, it should reset itself to connectionless (default) mode.

Definition at line 726 of file slavebase.cpp.

void SlaveBase::get const KURL   url [virtual]
 

get, aka read.

Parameters:
url  the full url for this request. Host, port and user of the URL can be assumed to be the same as in the last setHost() call. The slave emits the data through data

put, aka write.

Parameters:

permissions  may be -1. In this case no special permission mode is set.
overwrite  if true, any existing file will be overwritten. If the file indeed already exists, the slave should NOT apply the permissions change to it.

Definition at line 728 of file slavebase.cpp.

References error(), mProtocol, and KIO::unsupportedActionErrorString().

void SlaveBase::mimetype const KURL   url [virtual]
 

Finds mimetype for one file or directory.

This method should either emit 'mimeType' or it should send a block of data big enough to be able to determine the mimetype.

If the slave doesn't reimplement it, a get will be issued, i.e. the whole file will be downloaded before determining the mimetype on it - this is obviously not a good thing in most cases.

void SlaveBase::listDir const KURL   url [virtual]
 

Lists the contents of url.

The slave should emit ERR_CANNOT_ENTER_DIRECTORY if it doesn't exist, if we don't have enough permissions, or if it is a file It should also emit totalFiles as soon as it knows how many files it will list.

void SlaveBase::setTimeoutSpecialCommand int    timeout,
const QByteArray   data = QByteArray()
 

This function sets a timeout of timeout seconds and calls special(data) when the timeout occurs as if it was called by the application.

A timeout can only occur when the slave is waiting for a command from the application.

Specifying a negative timeout cancels a pending timeout.

Only one timeout at a time is supported, setting a timeout cancels any pending timeout.

Since:
3.1

void SlaveBase::listEntry const UDSEntry   _entry,
bool    ready
 

internal function to be called by the slave.

It collects entries and emits them via listEntries when enough of them are there or a certain time frame exceeded (to make sure the app gets some items in time but not too many items one by one as this will cause a drastic performance penalty)

Parameters:
ready  set to true after emitting all items. _entry is not used in this case

bool SlaveBase::openPassDlg KIO::AuthInfo   info,
const QString   errorMsg
 

Prompt the user for Authorization info (login & password).

Use this function to request authorization information from the end user. You can also pass an error message which explains why a previous authorization attempt failed. Here is a very simple example:

 KIO::AuthInfo authInfo;
 if ( openPassDlg( authInfo ) )
 {
    kdDebug() << QString::fromLatin1("User: ")
              << authInfo.username << endl;
    kdDebug() << QString::fromLatin1("Password: ")
              << QString::fromLatin1("Not displayed here!") << endl;
 }

You can also preset some values like the username, caption or comment as follows:

 KIO::AuthInfo authInfo;
 authInfo.caption= "Acme Password Dialog";
 authInfo.username= "Wile E. Coyote";
 QString errorMsg = "You entered an incorrect password.";
 if ( openPassDlg( authInfo, errorMsg ) )
 {
    kdDebug() << QString::fromLatin1("User: ")
              << authInfo.username << endl;
    kdDebug() << QString::fromLatin1("Password: ")
              << QString::fromLatin1("Not displayed here!") << endl;
 }

NOTE: A call to this function can fail and return false, if the UIServer could not be started for whatever reason.

Parameters:
info  See AuthInfo.
errorMsg  Error message to show
Returns:
true if user clicks on "OK", false otherwsie.

bool SlaveBase::checkCachedAuthentication AuthInfo   info
 

Checks for cached authentication based on parameters given by info.

Use this function to check if any cached password exists for the URL given by info. If AuthInfo::realmValue and/or AuthInfo::verifyPath flag is specified, then they will also be factored in determining the presence of a cached password. Note that Auth::url is a required parameter when attempting to check for cached authorization info. Here is a simple example:

 AuthInfo info;
 info.url = KURL("http://www.foobar.org/foo/bar");
 info.username = "somename";
 info.verifyPath = true;
 if ( !checkCachedAuthentication( info ) )
 {
    if ( !openPassDlg(info) )
     ....
 }
Parameters:
info  See AuthInfo.
Returns:
true if cached Authorization is found, false otherwise.

bool SlaveBase::requestNetwork const QString   host = QString::null
 

Used by the slave to check if it can connect to a given host.

This should be called where the slave is ready to do a connect() on a socket. For each call to requestNetwork must exist a matching call to dropNetwork, or the system will stay online until KNetMgr gets closed (or the SlaveBase gets destructed)!

If KNetMgr is not running, then this is a no-op and returns true

Parameters:
host  tells the netmgr the host the slave wants to connect to. As this could also be a proxy, we can't just take the host currenctly connected to (but that's the default value)
Returns:
true in theorie, the host is reachable false the system is offline and the host is in a remote network.

void SlaveBase::dropNetwork const QString   host = QString::null
 

Used by the slave to withdraw a connection requested by requestNetwork.

This function cancels the last call to requestNetwork. If a client uses more than one internet connection, it must use dropNetwork(host) to stop each request.

If KNetMgr is not running, then this is a no-op.

Parameters:
host  the host passed to requestNetwork
A slave should call this function every time it disconnect from a host.

bool SlaveBase::wasKilled  
 

If your ioslave was killed by a signal, wasKilled() returns true.

Check it regularly in lengthy functions (e.g. in get();) and return as fast as possible from this function if wasKilled() returns true. This will ensure that your slave destructor will be called correctly.

3.1
