◆ open()

void Euclid::Fits::FitsFile::open	(	const std::string &	filename,
		FileMode	permission
	)

protected

Open a Fits file with given filename and permission.

This method can only be used after having closed the file; It throws an exception otherwise. This method can be used to change the permission:

FitsFile f(filename, FileMode::Create);
... // Write things
f.close();
f.open(filename, FileMode::Read);
... // Read things

... but not to change the filename: If called with another filename, another Fits file will be opened.

Warning: In any case, relying on the constructors and destructors by managing the object lifetime is preferable.
