Detailed Description

This class implements the coding vector of coded packets which are internally represented using vectors of unsigned int variables, each of which holds 8*sizeof(unsigned int) coefficients. The internal representation of the coding vector is designed to be memory-efficient for coding vectors whose non-zero entries are closely packed.

Constructor & Destructor Documentation

Binc::CodingVector::CodingVector

(

unsigned int

position

)

Create a coding vector with a single bit set to one and all other bits set to zero

Parameters:

position

the position (bit number) of the bit set to one

Returns:

the created coding vector

Binc::CodingVector::CodingVector

(

const std::vector< unsigned int > &

v

)

Create a coding vector corresponding to the given vector of bitmasks

Parameters:

v

the vector of bitmasks

Member Function Documentation

bool Binc::CodingVector::At

(

unsigned int

position

)

const

Parameters:

n

the index of the coefficient (bit)

Returns:

the value of the coefficient (bit) with the given index

bool Binc::CodingVector::operator!=

(

const CodingVector &

rhs

)

const

Parameters:

rhs

the Right Hand Side

Returns:

true if the bit vectors are different in size or content, false otherwise

CodingVector & Binc::CodingVector::operator+=

(

const CodingVector &

rhs

)

Add the Right Hand Side of the operator to *this, bit by bit. Since we work over the GF2 (binary) field, this is equivalent to the bit by bit XOR operation.

Parameters:

rhs

the Right Hand Side

Returns:

a reference to *this

bool Binc::CodingVector::operator==

(

const CodingVector &

rhs

)

const

Parameters:

rhs

the Right Hand Side

Returns:

true if the bit vectors are equal in size and content, false otherwise

void Binc::CodingVector::Print

(

std::ostream &

os

)

const

Print the CodingVector

Parameters:

os

the stream to be used for printing

unsigned int Binc::CodingVector::Size

(

)

const

Returns:

the size in bits (not bytes!)

Friends And Related Function Documentation

CodingVector operator+	(	const CodingVector &	lhs,
		const CodingVector &	rhs
	)			[friend]

bitwise addition operator. Since we work over the GF2 (binary) field, this is equivalent to the bit by bit XOR operation.

Parameters:

	lhs	Left Hand Side of the operator
	rhs	Right Hand Side of the operator

Returns:

the value of lhs + rhs
