Detailed Description

The Q3UrlOperator class provides common operations on URLs.

network

This class operates on hierarchical structures (such as filesystems) using URLs. Its API facilitates all the common operations: Operation Function List files listChildren() Make a directory mkdir() Remove a file remove() Rename a file rename() Get a file get() Put a file put() Copy a file copy()

You can obtain additional information about the URL with isDir() and info(). If a directory is to be traversed using listChildren(), a name filter can be set with setNameFilter().

A Q3UrlOperator can be used like this, for example to download a file (and assuming that the FTP protocol is registered): 

    Q3UrlOperator *op = new Q3UrlOperator();
    op->copy( QString("ftp://ftp.trolltech.com/qt/source/qt-2.1.0.tar.gz"),
       "file:///tmp" );

If you want to be notified about success/failure, progress, etc., you can connect to Q3UrlOperator's signals, e.g. to start(), newChildren(), createdDirectory(), removed(), data(), dataTransferProgress(), startedNextCopy(), connectionStateChanged(), finished(), etc. A network operation can be stopped with stop().

The class uses the functionality of registered network protocols to perform these operations. Depending of the protocol of the URL, it uses an appropriate network protocol class for the operations. Each of the operation functions of Q3UrlOperator creates a Q3NetworkOperation object that describes the operation and puts it into the operation queue for the network protocol used. If no suitable protocol could be found (because no implementation of the necessary network protocol is registered), the URL operator emits errors. Not every protocol supports every operation, but error handling deals with this problem.

To register the available network protocols, use the qInitNetworkProtocols() function. The protocols currently supported are: FTP, HTTP, local file system.

const Q3NetworkOperation * Q3UrlOperator::listChildren (  )  [virtual]

Starts listing the children of this URL (e.g. the files in the directory). The start() signal is emitted before the first entry is listed and finished() is emitted after the last one. The newChildren() signal is emitted for each list of new entries. If an error occurs, the signal finished() is emitted, so be sure to check the state of the network operation pointer.

Because the operation may not be executed immediately, a pointer to the Q3NetworkOperation object created by this function is returned. This object contains all the data about the operation and is used to refer to this operation later (e.g. in the signals that are emitted by the Q3UrlOperator). The return value can also be 0 if the operation object couldn't be created.

The path of this Q3UrlOperator must to point to a directory (because the children of this directory will be listed), not to a file.

Tries to create a directory (child) with the name dirname.

Here is the call graph for this function:

const Q3NetworkOperation * Q3UrlOperator::get ( const QString &  location = QString()  )  [virtual]

Tells the network protocol to get data from location or, if it is empty, to get data from the location to which this URL points (see Q3Url::fileName() and Q3Url::encodedPathAndQuery()). What happens then depends on the network protocol. The data() signal is emitted when data comes in. Because it's unlikely that all data will come in at once, it is common for multiple data() signals to be emitted. The dataTransferProgress() signal is emitted while processing the operation. At the end, finished() (with success or failure) is emitted, so check the state of the network operation object to see whether or not the operation was successful.

If location is empty, the path of this Q3UrlOperator should point to a file when you use this operation. If location is not empty, it can be a relative URL (a child of the path to which the Q3UrlOperator points) or an absolute URL.

For example, to get a web page you might do something like this:

    Q3UrlOperator op( "http://www.whatever.org/cgi-bin/search.pl?cmd=Hello" );
    op.get();

For most other operations, the path of the Q3UrlOperator must point to a directory. If you want to download a file you could do the following:

    Q3UrlOperator op( "ftp://ftp.whatever.org/pub" );
    // do some other stuff like op.listChildren() or op.mkdir( "new_dir" )
    op.get( "a_file.txt" );

This will get the data of ftp://ftp.whatever.org/pub/a_file.txt.

Never do anything like this: 

    Q3UrlOperator op( "http://www.whatever.org/cgi-bin" );
    op.get( "search.pl?cmd=Hello" ); // WRONG!

If location is not empty and relative it must not contain any queries or references, just the name of a child. So if you need to specify a query or reference, do it as shown in the first example or specify the full URL (such as http://www.whatever.org/cgi-bin/search.pl?cmd=Hello) as location.

Here is the call graph for this function:

const Q3NetworkOperation * Q3UrlOperator::put ( const QByteArray &  data,
const QString &  location = QString() 
) [virtual]

This function tells the network protocol to put data in location. If location is empty, it puts the data in the location to which the URL points. What happens depends on the network protocol. Depending on the network protocol, some data might come back after putting data, in which case the data() signal is emitted. The dataTransferProgress() signal is emitted during processing of the operation. At the end, finished() (with success or failure) is emitted, so check the state of the network operation object to see whether or not the operation was successful.

If location is empty, the path of this Q3UrlOperator should point to a file when you use this operation. If location is not empty, it can be a relative (a child of the path to which the Q3UrlOperator points) or an absolute URL.

For putting some data to a file you can do the following:

    Q3UrlOperator op( "ftp://ftp.whatever.com/home/me/filename.dat" );
    op.put( data );

For most other operations, the path of the Q3UrlOperator must point to a directory. If you want to upload data to a file you could do the following:

    Q3UrlOperator op( "ftp://ftp.whatever.com/home/me" );
    // do some other stuff like op.listChildren() or op.mkdir( "new_dir" )
    op.put( data, "filename.dat" );

This will upload the data to ftp://ftp.whatever.com/home/me/filename.dat.

Here is the call graph for this function:

Q3PtrList< Q3NetworkOperation > Q3UrlOperator::copy ( const QString &  from,
const QString &  to,
bool  move = false,
bool  toPath = true 
) [virtual]

Copies the file from to to. If move is true, the file is moved (copied and removed). from must point to a file and to must point to a directory (into which from is copied) unless toPath is set to false. If toPath is set to false then the to variable is assumed to be the absolute file path (destination file path + file name). The copying is done using the get() and put() operations. If you want to be notified about the progress of the operation, connect to the dataTransferProgress() signal. Bear in mind that the get() and put() operations emit this signal through the Q3UrlOperator. The number of transferred bytes and the total bytes that you receive as arguments in this signal do not relate to the the whole copy operation; they relate first to the get() and then to the put() operation. Always check what type of operation the signal comes from; this is given in the signal's last argument.

At the end, finished() (with success or failure) is emitted, so check the state of the network operation object to see whether or not the operation was successful.

Because a move or copy operation consists of multiple operations (get(), put() and maybe remove()), this function doesn't return a single Q3NetworkOperation, but rather a list of them. They are in the order: get(), put() and (if applicable) remove().

void Q3UrlOperator::copy ( const QStringList &  files,
const QString &  dest,
bool  move = false 
) [virtual]

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Copies the files to the directory dest. If move is true the files are moved, not copied. dest must point to a directory.

This function calls copy() for each entry in files in turn. You don't get a result from this function; each time a new copy begins, startedNextCopy() is emitted, with a list of Q3NetworkOperations that describe the new copy operation.

bool Q3UrlOperator::isDir ( bool *  ok = 0  )  [virtual]

Returns true if the URL is a directory; otherwise returns false. This may not always work correctly, if the protocol of the URL is something other than file (local filesystem). If you pass a bool pointer as the ok argument, *ok is set to true if the result of this function is known to be correct, and to false otherwise.
