Detailed Description

Class loading project files.

This class opens an file and reads it line by line. It delegates the actual parsing to each of the known WProjectFileIO instances which then do their job.

Parameters:
parserthe parser to remove. If not existing, nothing happens.

References m_additionalParsers, and WSharedSequenceContainer< S >::remove().

boost::shared_ptr< WProjectFileIO > WProjectFile::getCameraWriter ( ) [static]

Returns an instance of the Camera writer.

Returns:
the writer able to output the camera configuration to a stream.

Definition at line 146 of file WProjectFile.cpp.

boost::shared_ptr< WProjectFileIO > WProjectFile::getModuleWriter ( ) [static]

Returns an instance of the module writer.

Returns:
the writer able to output the module configuration to a stream.

boost::shared_ptr< WProjectFileIO > WProjectFile::getROIWriter ( ) [static]

Returns an instance of the ROI writer.

Returns:
the writer able to output the ROI configuration to a stream.

Definition at line 156 of file WProjectFile.cpp.

void WProjectFile::load ( ) [virtual]

Parses the project file and applies it.

It applies the project file asynchronously!

Definition at line 161 of file WProjectFile.cpp.

References WKernel::getRootContainer(), WKernel::getRunningKernel(), and WThreadedRunner::run().

unsigned int WProjectFile::mapFromModule ( boost::shared_ptr< WModule module) const

Map a given module to project file ID.

This method must not be used by WModuleProjectFileCombiner, as it builds this mapping. All other WProjectFileIO implementations are allowed to use it in their save and apply methods (NOT in parse()).

Parameters:
modulethe module to map
Returns:
the ID, or numeric_limits< unisigned int >::max() if module not known.*

Definition at line 329 of file WProjectFile.cpp.

References m_moduleIO.

boost::shared_ptr< WModule > WProjectFile::mapToModule ( unsigned int  id) const

Map a given project file ID to a module.

This method must not be used by WModuleProjectFileCombiner, as it builds this mapping. All other WProjectFileIO implementations are allowed to use it in their save and apply methods (NOT in parse()).

Parameters:
idthe id
Returns:
the module, or NULL if ID is not known.

void WProjectFile::onThreadException ( const WException e) [protected, virtual]

Do custom exception handling.

Parameters:
ethe exception

Reimplemented from WThreadedRunner.

Definition at line 294 of file WProjectFile.cpp.

References WKernel::getRootContainer(), WKernel::getRunningKernel(), and WThreadedRunner::handleDeadlyException().

Register a custom project file parser.

Use this to add and re-read information from project files. The change takes effect when creating a new instance of WProjectFile. The custom parser needs to implement WProjectFileIO::clone as this is used for instancing the parser for each project file.

Notes:
: See WQtNetworkEditorProjectFileIO for a working example.
Parameters:
parserthe parser. Can be added multiple times.
