void sim::DumpMCTracks::DumpMCTrack	(	Stream &&	out,
		sim::MCTrack const &	track,
		std::string	indent = "",
		bool	bIndentFirst = true
	)		const

Dumps the content of the specified particle in the output stream.

Template Parameters

Stream

the type of output stream

Parameters

out	the output stream
particle	the particle to be dumped
indent	base indentation string (default: none)
bIndentFirst	if first output line should be indented (default: yes)

The indent string is prepended to every line of output, with the possible exception of the first one, in case bIndentFirst is true.

The output starts on the current line, and the last line is NOT broken.
