Constructor & Destructor Documentation

FileIOChacoPartitioner::FileIOChacoPartitioner	(	const std::string &	filename,
		bool	ignoreGhosts = `false`
	)

Construct an empty mesh filter object

void FileIOChacoPartitioner::getAssignments	(	const Mesh &	mesh,
		int	np,
		Array< int > &	assignments
	)		const `[virtual]`

bool FileIOChacoPartitioner::getNextLine	(	std::istream &	is,
		std::string &	line,
		Array< string > &	tokens,
		char	comment
	)		const `[private]`

Read the next non-empty, non-comment line from a stream

Parameters:

is	the stream from which to get the line
line	upon return, filled in with the line that was read
tokens	array of space-separated tokens in the line
comment	a character indicating that everything after it is a comment

bool FileIOChacoPartitioner::isEmptyLine ( const std::string & x ) const [private]

Determine whether a line is empty
