inline

All bits are set to the specified state.

NodeMask ( const NodeMask< 1 > &  other)
inline

Copy constructor.

~NodeMask ( )
inline

Destructor.

const NodeMask& foreach ( const NodeMask< 1 > &  other,
const WordOp &  op 
)
inline

Apply a functor to the words of the this and the other mask.

An example that implements the "operator&=" method:

struct Op { inline void operator()(Word &w1, const Word& w2) const { w1 &= w2; } };
const NodeMask& foreach ( const NodeMask< 1 > &  other1,
const NodeMask< 1 > &  other2,
const WordOp &  op 
)
inline
const NodeMask& foreach ( const NodeMask< 1 > &  other1,
const NodeMask< 1 > &  other2,
const NodeMask< 1 > &  other3,
const WordOp &  op 
)
inline
bool isConstant ( bool &  isOn) const
inline

Return true if bits are either all off OR all on.

Parameters
isOnTakes on the values of all bits if the method returns true - else it is undefined.
bool isOff ( Index32  n) const
inline

Return true if the nth bit is off.

bool isOff ( ) const
inline

Return true if all the bits are off.

bool isOn ( Index32  n) const
inline

Return true if the nth bit is on.

bool isOn ( ) const
inline

Return true if all the bits are on.
