Classes
struct	bitInfo< UIntType >
	An (unsigned) integral type adapter, for output of bit values. More...

Namespaces
namespace	Foam::BitOps
	Various bit-wise operations and adaptor methods for containers that are somewhat similar to bitSet (eg, boolList, labelHashSet).
namespace	Foam::BitSetOps
	Factory and other methods for bitSet. Adaptor methods for other containers that are somewhat similar to bitSet (eg, boolList, labelHashSet).
namespace	Foam
	Namespace for OpenFOAM.

Functions
unsigned int	count (const UList< bool > &bools, const bool val=true)
	Count number of 'true' entries.
bool	all (const UList< bool > &bools)
	True if all entries are 'true' or if the list is empty.
bool	any (const UList< bool > &bools)
	True if any entries are 'true'.
bool	none (const UList< bool > &bools)
	True if no entries are 'true'.
void	set (List< bool > &bools, const labelUList &locations)
	Set the listed locations (assign 'true').
void	set (List< bool > &bools, const labelRange &range)
	Set the specified range 'on' in a boolList.
void	set (labelHashSet &hashset, const labelRange &range)
	Set the specified range in a labelHashSet.
void	set (bitSet &bitset, const labelRange &range)
	Forward to bitSet::set(labelRange).
void	unset (List< bool > &bools, const labelUList &locations)
	Unset the listed locations (assign 'false').
void	unset (List< bool > &bools, const labelRange &range)
	Unset the specified range 'on' in a boolList.
void	unset (labelHashSet &hashset, const labelRange &range)
	Unset the specified range in a labelHashSet.
void	unset (bitSet &bitset, const labelRange &range)
	Forward to bitSet::unset(labelRange).
List< bool >	select (const label n, const labelUList &locations)
	Construct a selection list of bools (all false) with the given pre-size, subsequently add specified locations as true, auto-vivify entries if needed.
List< bool >	select (const labelUList &locations)
	Construct an auto-sized selection list of bools (all false), and populate the specified locations as true.
unsigned int	count (const bitSet &bitset, const bool on=true)
	Forward to bitSet::count().
List< label >	toc (const UList< bool > &bools)
	Return the (sorted) values corresponding to 'true' entries.
List< label >	sortedToc (const UList< bool > &bools)
	Return the (sorted) values corresponding to 'true' entries.
List< label >	toc (const bitSet &bitset)
	Forward to bitSet::toc(), the sorted values of the 'on' entries.
List< label >	sortedToc (const bitSet &bitset)
	Forward to bitSet::sortedToc(), the sorted values of the 'on' entries.
List< label >	toc (const labelHashSet &hashset)
	Forward to labelHashSet::sortedToc(), the sorted values of the 'on' entries.
List< label >	sortedToc (const labelHashSet &hashset)
	Forward to labelHashSet::sortedToc(), the sorted values of the 'on' entries.
template<class UIntType>

template<class UIntType>
Ostream &	print (Ostream &os, UIntType value, char off='0', char on='1')
	Print 0/1 bits in the (unsigned) integral type.
bitSet	create (const label n, const labelHashSet &locations, const bool on=true)
	Create a bitSet with length n with the specified on locations.
bitSet	create (const label n, const labelUList &locations, const bool on=true)
	Create a bitSet with length n with the specified on locations.
bitSet	create (const label n, const label select, const labelUList &values, const bool on=true)
	Create a bitSet with length n with the specified on locations when the list values are equal to the select value.
template<class UIntType>
Ostream &	operator<< (Ostream &os, const BitOps::bitInfo< UIntType > &info)
