Detailed Description

BitVector is a specialization of STL's bit vector. It provides some handy helper methods.

Constructor & Destructor Documentation

BitVector() [1/2]

BitVector::BitVector

(

)

The constructor.

Definition at line 44 of file BitVector.cc.

                     {
}

BitVector() [2/2]

BitVector::BitVector	(	const BitVector &	vector,
		unsigned int	firstIndex,
		unsigned int	lastIndex
	)

The constructor.

Creates a bit vector that is a sub vector of the given vector.

Parameters

vector	The bit vector.
firstIndex	The index of the given vector that is to be the first element in the created vector.
lastIndex	The index of the given vector that is to be that last element in the created vector.

Exceptions

OutOfRange

If the given indexes are too big or too small.

                                                                              {
    if (lastIndex < firstIndex || lastIndex >= vector.size()) {
        const string procName = "BitVector::BitVector";
        throw OutOfRange(__FILE__, __LINE__, procName);
    }
 
    BitVector::const_iterator firstIter = vector.begin();
    firstIter += firstIndex;
    BitVector::const_iterator lastIter = vector.begin();
    lastIter += lastIndex + 1;
    insert(begin(), firstIter, lastIter);
    assert(size() == lastIndex - firstIndex + 1);
}

Member Function Documentation

pushBack() [1/3]

void BitVector::pushBack

(

bool

bit

)

Pushes back the given bit.

Parameters

bit	The bit to be added.

Definition at line 120 of file BitVector.cc.

                            {
    push_back(bit);
}

pushBack() [2/3]

void BitVector::pushBack

(

const BitVector &

bits

)

Pushes back the given bit vector.

Parameters

bits	The bit vector.

Definition at line 107 of file BitVector.cc.

                                         {
    reserve(size() + bits.size());
    for (std::vector<bool>::const_iterator iter = bits.begin();
         iter != bits.end(); iter++) {
        push_back(*iter);
    }
}

pushBack() [3/3]

void BitVector::pushBack	(	long long unsigned int	integer,
		int	size
	)

Pushes back the given number and increases the size of the vector by the given amount.

For example, if number 6 (110) is added with size 5, bits 00110 are concatenated to the vector. If size 2 is given, then bits 10 are concatenated to the vector.

Parameters

integer	The number to be added.
size	The number of bits to be added.

Definition at line 94 of file BitVector.cc.

                                                            {
    for (int i = size - 1; i >= 0; i--) {
        push_back(MathTools::bit(integer, i));
    }
}
