A set of booleans.
Note that there are only four possible such sets. NBoolSet objects are small enough to pass about by value instead of by reference.

inline 
Creates a new empty set.

inline 
Creates a set containing a single member as given.
member  the single element to include in this set. 

inline 
Creates a set equal to the given set.
cloneMe  the set upon which we will base the new set. 

inline 
Creates a set specifying whether true
and/or false
should be a member.
insertTrue  should the new set include the element true ? 
insertFalse  should the new set include the element false ? 

inline 
Determines if the given boolean is a member of this set.
value  the boolean to search for in this set. 
true
if and only if the given boolean is a member of this set.

inline 
Removes all elements from this set.

inline 
Places both true
and false
into this set if they are not already present.

inlinestatic 
Creates a boolean set from the given byte code.
See getByteCode() for more information on byte codes.
code  the byte code from which the new set will be created. 

inline 
Returns the byte code representing this boolean set.
The byte code is sufficient to reconstruct the set and is thus a useful means for passing boolean sets to and from the engine.
The lowest order bit of the byte code is 1 if and only if true
is in the set. The next lowest order bit is 1 if and only if false
is in the set. All other bits are 0. Thus sets NBoolSet::sNone, NBoolSet::sTrue, NBoolSet::sFalse and NBoolSet::sBoth have byte codes 0, 1, 2 and 3 respectively.

inline 
Determines if false
is a member of this set.
true

is a member of this set.

inline 
Determines if true
is a member of this set.
true
if and only if true
is a member of this set.

inline

into this set if it is not already present.

inline

other  the set to compare with this. 
true
if and only if this and the given set are not equal. Returns the intersection of this set with the given set.
The result is a set containing precisely the elements that belong to both original sets. This set is not changed.

Sets this set to be the intersection of this and the given set.
The result is a set containing precisely the elements that belong to both original sets. Note that this set will be modified.

inline 
Determines if this set is a superset of (possibly equal to) the given set.
other  the set to compare with this. 
true
if and only if this is a superset of the given set. Returns the symmetric difference of this set and the given set.
The result is a set containing precisely the elements that belong to one but not both of the original sets. This set is not changed.

The result is a set containing precisely the elements that belong to either of the original sets. This set is not changed.
other  the set to union with this set. 
Sets this set to be the union of this and the given set.
The result is a set containing precisely the elements that belong to either of the original sets. Note that this set will be modified.
