## Detailed Description

Base class for reader modules.

Reader modules access persistent data and pass them to the desired data structure by the means of a BaseImporter derivative. All reader modules must be derived from this class.

## Member Function Documentation

virtual bool OpenMesh::IO::BaseReader::read | ( | const std::string & | _filename,
|  | BaseImporter & | _bi,
|  | Options & | _opt
| ) |  |
| pure virtual

Reads a mesh given by a filename.

Usually this method opens a stream and passes it to stream read method. Acceptance checks by filename extension can be placed here.

Options can be passed via _opt. After execution _opt contains the Options that were available

Implemented in OpenMesh::IO::_OFFReader_, OpenMesh::IO::_PLYReader_, OpenMesh::IO::_STLReader_, OpenMesh::IO::_OMReader_, and OpenMesh::IO::_OBJReader_.

virtual bool OpenMesh::IO::BaseReader::read | ( | std::istream & | _is,
|  | BaseImporter & | _bi,
|  | Options & | _opt
| ) |  |
| pure virtual

Reads a mesh given by a std::stream.

This method usually uses the same stream reading method that read uses. Options can be passed via _opt. After execution _opt contains the Options that were available.

Please make sure that if _is is std::ifstream, the correct std::ios_base::openmode flags are set.

Implemented in OpenMesh::IO::_OFFReader_, OpenMesh::IO::_PLYReader_, OpenMesh::IO::_STLReader_, OpenMesh::IO::_OMReader_, and OpenMesh::IO::_OBJReader_.
