Public Types
typedef PatternCouplet	Couplet
typedef std::vector< Couplet >	Couplets
typedef const Couplet *	Iterator

Public Member Functions
	PatternBuilder (std::pair< int, int > IJ)
	Constructor, requires size (I,J). Initialized to empty (contains no nonzeros).
	PatternBuilder (int in_I, int in_J)
	PatternBuilder (const PatternBuilder &that)
	Copy constructor.
void	swap (PatternBuilder &that)
	Member swap.
	PatternBuilder (PatternBuilder &&that)
	Move constructor, default-construct and swap idiom.
PatternBuilder &	operator= (PatternBuilder that)
	Assignment operator, copy and swap idiom.
PatternBuilder &	operator= (const PatternRange &that)
	Assignment operator from a PatternRange.
	PatternBuilder (const PatternRange &that)
	Constructs from a PatternRange.
	PatternBuilder (InputStream &in)
	InputStream constructor. Layout compatible with Pattern.
void	write (OutputStream &out) const
	Writes to OutputStream. Layout compatible with Pattern.
void	insert (int i, int j)
	Inserts a single structural nonzero.
void	insert_row (int i, const intCRange &j_pattern)
	Inserts a row of nonzeros.
void	insert_column (const intCRange &i_pattern, int j)
	Inserts a column of nonzeros.
void	insert_tensor (const intCRange &i_pattern, const intCRange &j_pattern)
	Inserts a tensor product of nonzeros.
void	insert_tensor (const intCRange &ij_pattern)
	Inserts a symmetric tensor product of nonzeros.
void	insert (const PatternBuilder &that, int i_offset=0, int j_offset=0)
	Inserts all the nonzeros from a Pattern into *this.
void	insert (const PatternRange &that, int i_offset=0, int j_offset=0)
void	erase (int i, int j)
	Erases a single structural nonzero. Note this is exceedingly slow, linear complexity.
Iterator	begin () const
	Presents a const range of (i,j) couplets. Note this range may contain duplicates.
Iterator	end () const
std::pair< int, int >	size () const
	Size inspector.
Pattern	make_Pattern () const
	Returns an equivalent Pattern.

Static Public Member Functions
static PatternBuilder	identity (int IJ)
	Generates an identity PatternBuilder of specified size.
static PatternBuilder	random (std::pair< int, int > IJ, int N)
	Generates a random PatternBuilder with size IxJ and (approximately) N nonzeros.
static PatternBuilder	random (int I, int J, int N)
