All Methods Instance Methods Abstract Methods Modifier and Type Method Description void
add(long newdata)
Adding words directly to the bitmap (for expert use).void
addStreamOfEmptyWords(boolean v, long number)
For experts: You want to add many zeroes or ones? This is the method you use.void
addStreamOfLiteralWords(long[] data, int start, int number)
if you have several literal words to copy over, this might be faster.void

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
-
addStreamOfLiteralWords
void addStreamOfLiteralWords(long[] data, int start, int number)
if you have several literal words to copy over, this might be faster.- Parameters:
data
- the literal wordsstart
- the starting point in the arraynumber
- the number of literal words to add
-
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 onesnumber
- how many to words add
-
addStreamOfNegatedLiteralWords
void addStreamOfNegatedLiteralWords(long[] data, int start, int number)
Like "addStreamOfLiteralWords" but negates the words being added.- Parameters:
data
- the literal wordsstart
- the starting point in the arraynumber
- the number of literal words to add
-
setSizeInBits
void setSizeInBits(int bits)
directly set the sizeinbits field- Parameters:
bits
- number of bits
