int LastBit() const
The LastBit
method returns the index of the last bit, i.e.
the set bit with the highest index, in the OEBitVector
. Bit
position indices are numbered from zero, and have a maximum of
OEBitVector::GetSize()-1
. If the OEBitVector
has no bits set,
i.e. OEBitVector::IsEmpty
returns true, this method return
will return the value -1.
