Detailed Description

This is the real IOManager class that is later encapsulated by SingletonT to enforce its uniqueness. IOManager is not meant to be used directly by the programmer - the IOManager alias exists for this task.

All reader/writer modules register themselves at this class. For reading or writing data all modules are asked to do the job. If no suitable module is found, an error is returned.

For the sake of reading, the target data structure is hidden behind the BaseImporter interface that takes care of adding vertices or faces.

Writing from a source structure is encapsulate similarly behind a BaseExporter interface, providing iterators over vertices/faces to the writer modules.

Member Function Documentation

qt_read_filters()

const std::string& OpenMesh::IO::_IOManager_::qt_read_filters ( ) const

inline

Returns all readable file extension + descriptions in one string. File formats are separated by ;;. Convenience function for Qt file dialogs.

Definition at line 189 of file IOManager.hh.

qt_write_filters()

const std::string& OpenMesh::IO::_IOManager_::qt_write_filters ( ) const

inline

Returns all writeable file extension + descriptions in one string. File formats are separated by ;;. Convenience function for Qt file dialogs.

read() [1/2]

bool OpenMesh::IO::_IOManager_::read	(	const std::string &	_filename,
		BaseImporter &	_bi,
		Options &	_opt
	)

Read a mesh from file _filename. The target data structure is specified by the given BaseImporter. The read method consecutively queries all of its reader modules. True is returned upon success, false if all reader modules failed to interprete _filename.

Definition at line 87 of file IOManager.cc.

read() [2/2]

bool OpenMesh::IO::_IOManager_::read	(	std::istream &	_filename,
		const std::string &	_ext,
		BaseImporter &	_bi,
		Options &	_opt
	)

Read a mesh from open std::istream _is. The target data structure is specified by the given BaseImporter. The sread method consecutively queries all of its reader modules. True is returned upon success, false if all reader modules failed to use _is.

Definition at line 118 of file IOManager.cc.

register_module() [1/2]

bool OpenMesh::IO::_IOManager_::register_module ( BaseReader *  _bl )

inline

Registers a new reader module. A call to this function should be implemented in the constructor of all classes derived from BaseReader.

Definition at line 217 of file IOManager.hh.

register_module() [2/2]

bool OpenMesh::IO::_IOManager_::register_module ( BaseWriter *  _bw )

inline

Registers a new writer module. A call to this function should be implemented in the constructor of all classed derived from BaseWriter.

Definition at line 229 of file IOManager.hh.

write() [1/2]

bool OpenMesh::IO::_IOManager_::write	(	const std::string &	_filename,
		BaseExporter &	_be,
		Options	_opt = Options::Default,
		std::streamsize	_precision = 6
	)

Write a mesh to file _filename. The source data structure is specified by the given BaseExporter. The save method consecutively queries all of its writer modules. True is returned upon success, false if all writer modules failed to write the requested format. Options is determined by _filename's extension.

Definition at line 143 of file IOManager.cc.

write() [2/2]

bool OpenMesh::IO::_IOManager_::write	(	std::ostream &	_filename,
		const std::string &	_ext,
		BaseExporter &	_be,
		Options	_opt = Options::Default,
		std::streamsize	_precision = 6
	)

Write a mesh to open std::ostream _os. The source data structure is specified by the given BaseExporter. The save method consecutively queries all of its writer modules. True is returned upon success, false if all writer modules failed to write the requested format. Options is determined by _filename's extension.
