public interface BitmapStorage

Low level bitset writing methods.

Method Summary

void	add(long newdata) Adding words directly to the bitmap (for expert use).
void	addStreamOfDirtyWords(long[] data, int start, int number) if you have several dirty words to copy over, this might be faster.
void	addStreamOfEmptyWords(boolean v, long number) For experts: You want to add many zeroes or ones? This is the method you use.
void	addStreamOfNegatedDirtyWords(long[] data, int start, int number) Like "addStreamOfDirtyWords" but negates the words being added.
void	setSizeInBits(int bits) directly set the sizeinbits field

Method Detail

add

void add(long 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

addStreamOfEmptyWords

void addStreamOfEmptyWords(boolean v,
                           long 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

addStreamOfDirtyWords

void addStreamOfDirtyWords(long[] data,
                           int start,
                           int number)

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

Parameters:

data - the dirty words

start - the starting point in the array

number - the number of dirty words to add

addStreamOfNegatedDirtyWords

void addStreamOfNegatedDirtyWords(long[] data,
                                  int start,
                                  int number)

Like "addStreamOfDirtyWords" but negates the words being added.

Parameters:

data - the dirty words

start - the starting point in the array

number - the number of dirty words to add

setSizeInBits

void setSizeInBits(int bits)

directly set the sizeinbits field

Parameters:

bits - number of bits
