Method Summary

Modifier and Type	Method and Description
void	addStreamOfEmptyWords(boolean v, int number) For experts: You want to add many zeroes or ones? This is the method you use.
void	addStreamOfLiteralWords(int[] data, int start, int number) if you have several literal words to copy over, this might be faster.
void	addStreamOfNegatedLiteralWords(int[] data, int start, int number) Like "addStreamOfLiteralWords" but negates the words being added.
void	addWord(int newData) Adding words directly to the bitmap (for expert use).
void	clear() Empties the container.
void	setSizeInBits(int bits) directly set the sizeInBits field

Method Detail

addWord

void addWord(int newData)

Adding words directly to the bitmap (for expert use). This is normally how you add data to the array. So you add bits in streams of 8*8 bits.

Parameters:

newData - the word

addStreamOfLiteralWords

void addStreamOfLiteralWords(int[] data,
                             int start,
                             int number)

if you have several literal words to copy over, this might be faster.

Parameters:

data - the literal words

start - the starting point in the array

number - the number of literal words to add

addStreamOfEmptyWords

void addStreamOfEmptyWords(boolean v,
                           int number)

For experts: You want to add many zeroes or ones? This is the method you use.

Parameters:

v - zeros or ones

number - how many to words add

addStreamOfNegatedLiteralWords

void addStreamOfNegatedLiteralWords(int[] data,
                                    int start,
                                    int number)

Like "addStreamOfLiteralWords" but negates the words being added.

Parameters:

data - the literal words

start - the starting point in the array

number - the number of literal words to add

clear

void clear()

Empties the container.

setSizeInBits

void setSizeInBits(int bits)

directly set the sizeInBits field

Parameters:

bits - number of bits
