Detailed Description

Implementation of OutputFileFormat paradigm for the Interfile format.

Member Function Documentation

◆ set_byte_order()

ByteOrder stir::InterfileDynamicDiscretisedDensityOutputFileFormat::set_byte_order	(	const ByteOrder &	,
		const bool	warn = `false`
	)

overridevirtual

set byte order used for output

Returns type actually used. Calls warning() with some text if the requested type is not supported.

Default implementation accepts any byte order.

Reimplemented from stir::OutputFileFormat< DynamicDiscretisedDensity >.

References stir::ByteOrder::is_native_order(), and stir::warning().

◆ actual_write_to_file()

Succeeded stir::InterfileDynamicDiscretisedDensityOutputFileFormat::actual_write_to_file	(	std::string &	filename,
		const DynamicDiscretisedDensity &	density
	)		const

overrideprotectedvirtual

virtual function called by write_to_file()

This function has to be overloaded by the derived class.

The reason we do not simply make write_to_file() virtual is that we have 2 versions of write_to_file. C++ rules are such that overloading the virtual function in a derived class means that the other version gets hidden. Having the non-virtual write_to_file() call the virtual actual_write_to_file() solves this problem.

Implements stir::OutputFileFormat< DynamicDiscretisedDensity >.
