Modifier and Type | Method and Description |
---|---|
void |
andLastWord(long mask)
Replaces the last word position in the buffer
with its bitwise-and with the given mask.
|
void |
andWord(int position,
long mask)
Replaces the word at the given position in the buffer
with its bitwise-and with the given mask.
|
void |
clear()
Resets the buffer
The buffer is not fully cleared and any new set operations should
overwrite stale data
|
LongBufferWrapper |
clone()
Creates and returns a copy of the buffer
|
void |
collapse(int position,
int length)

|
void |
expand(int position,
int length)
Expands the buffer by adding the given number of words at the given position.
|
long |
getLastWord()
Returns the last word of the buffer
|
long |
getWord(int position)
Returns the word at a given position
|
void |
negateWord(int position)
Negates the word at the given position in the buffer
|
void |
negative_push_back(Buffer buffer,
int start,
int number)
Same as push_back, but the words are negated.
|
void |
orLastWord(long mask)
Replaces the last word position in the buffer
with its bitwise-or with the given mask.
|
void |
orWord(int position,
long mask)
Replaces the word at the given position in the buffer
with its bitwise-or with the given mask.
|
void |
push_back(Buffer buffer,
int start,
int number)
Appends the specified buffer words to the end of the buffer.
|
void |
push_back(long word)
Appends the specified word to the end of the buffer
|
void |
removeLastWord()
Removes the last word from the buffer
|
void |
setLastWord(long word)
Replaces the last word in the buffer with
the specified word.
|
void |
setWord(int position,
long word)
Replaces the word at the given position in the buffer with
the specified word.
|
int |
sizeInWords()
