Detailed Description

The TulipProject object handles the content of a Tulip project.

All tulip projects contain a set of defined static meta-informations:

name (QString): the name of the project
description (QString): Comments about the project
author (QString): the author of the project
perspective (QString): the name of the perspective plugin associated to the project
date (QDate): the date of project's last modification
version (QString): the version of the Tulip project format

Alongside those informations, one can store any kind of file into a Tulip project. Since a project is meant to be associated to a specific perspective, the responisbility of those file is left to the perspective.

A TulipProject DOES NOT automatically save to disk. One will have to call the write() method to serialize data.

Warning: Precise implementation of the TulipProject object should NOT be known or used by the user since it could be subject to changes.

If something wrong happens when calling a method from TulipProject, this method will return either false or a invalid result (see specific method documentation). The last error message can be retrieved with the lastError() method.

After opening and before saving a project, user will be able to list/delete files and directories available in the project and open them using std filestreams or Qt's QIODevice. Files can be opened using the stdFileStram and fileStream methods. They will always be opened in Read/Write mode.

Files in a tulip project are identified by their path. Those path ar similar to the path of a standard file system and use the "/" character as a separator. The root directory is identified by "/".

Warning: TulipProject paths ALWAYS use the "/" character as a directory separator. This is OS-independant.

Note: A file called graph.tlp located at the top-level directory will be identified by the "/graph.tlp" path while the file "graph.tlp" located in the "data" directory will be identified by "/data/graph.tlp".

QString tlp::TulipProject::absoluteRootPath ( ) const

This method returns the real absolute path corresponding to / in the TulipProject.

QIODevice* tlp::TulipProject::fileStream	(	const QString &	path,
		QIODevice::OpenMode	mode = `QIODevice::ReadWrite`
	)

Gets a Qt I/O device (default to R/W access mode) to the given path.

Warning: This method does not check if the given path is a directory or a file. User might get an invalid filestream.; User SHOULD NOT cast the QIODevice returned by this method into any of its subclass since the implementation might change in future versions.; It is up to the user to delete the QIODevice returned.

Parameters

path	The path to open.

See Also: TulipProject

Parameters

mode	The opening mode as described in the Qt documentation.

Returns: an opened Qt device on the given path.

bool tlp::TulipProject::isDir ( const QString & path )

Checks if the given path is a directory.

Parameters

path	The path to check.

See Also: TulipProject

Returns: true/false wether the path is a directory.

bool tlp::TulipProject::isValid ( ) const

inline

Check if the object is a valid TulipProject.

Warning: Calling methods on invalid TulipProject instances may result in undefined behavior.

Definition at line 241 of file TulipProject.h.

QString tlp::TulipProject::lastError ( ) const

inline

Returns the last error raised.

Note: The returned string is null if no error was raised.

Definition at line 232 of file TulipProject.h.

bool tlp::TulipProject::mkpath ( const QString & path )

Recursively creates the specified path.

Created folders will be empty

Returns: true if path was successfully created.

QString tlp::TulipProject::name ( ) const

See Also: name

static TulipProject* tlp::TulipProject::newProject ( )

static

Starts a new TulipProject from scratch.

This method builds up a new TulipProject file without taking any input.

See Also: openProject()

static TulipProject* tlp::TulipProject::openProject	(	const QString &	file,
		tlp::PluginProgress *	progress = `NULL`
	)

static

Opens a previously saved tulip project file.

This method will unpack a tulip project file into some directory and allow the user to manipulate the files.

See Also: TulipProject::save()

Parameters

file	The file to open.
progress	A progress handler.

Returns: a pointer to a TulipProject object.

QString tlp::TulipProject::perspective ( ) const

See Also: perspective

QString tlp::TulipProject::projectFile ( ) const

inline

Return the archive file associated with this project.

If the project has been opened from an existing file or if the write method has already been called, this method will return the last file path specified. In other cases, this method will return an empty string.

Definition at line 251 of file TulipProject.h.

bool tlp::TulipProject::removeAllDir ( const QString & path )

Removes a directory and all its content from the project.

If the given file points to a file, or if the directory does not exist, this method will fail and return false.

Warning: This will remove every file stored in the specified directory.

Parameters

path	The path to delete.
