IntArray, IntBufferWrapper

interface Buffer32

Buffer interface. Users should not be concerned by this class.

Method Summary

Modifier and Type	Method and Description
void	andLastWord(int mask) Replaces the last word position in the buffer with its bitwise-and with the given mask.
void	andWord(int position, int 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
Buffer32	clone() Creates and returns a copy of the buffer
void	collapse(int position, int length) Removes a given number of words at the given position in the buffer.
void	ensureCapacity(int capacity) Increases the size of the buffer if necessary
void	expand(int position, int length) Expands the buffer by adding the given number of words at the given position.
int	getLastWord() Returns the last word of the buffer
int	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(Buffer32 buffer, int start, int number) Same as push_back, but the words are negated.
void	orLastWord(int mask) Replaces the last word position in the buffer with its bitwise-or with the given mask.
void	orWord(int position, int mask) Replaces the word at the given position in the buffer with its bitwise-or with the given mask.
void	push_back(Buffer32 buffer, int start, int number) Appends the specified buffer words to the end of the buffer.
void	push_back(int word) Appends the specified word to the end of the buffer
void	removeLastWord() Removes the last word from the buffer
void	setLastWord(int word) Replaces the last word in the buffer with the specified word.
void	setWord(int position, int word) Replaces the word at the given position in the buffer with the specified word.
int	sizeInWords() Returns the actual size in words
void	swap(Buffer32 other) Swap the content of the buffer with another.
void	trim() Reduces the internal buffer to its minimal allowable size.

Method Detail

sizeInWords

int sizeInWords()

Returns the actual size in words

ensureCapacity

void ensureCapacity(int capacity)

Increases the size of the buffer if necessary

getWord

int getWord(int position)

Returns the word at a given position

Parameters:

position -

Returns:

the word

getLastWord

int getLastWord()

Returns the last word of the buffer

Returns:

the last word

clear

void clear()

Resets the buffer The buffer is not fully cleared and any new set operations should overwrite stale data

trim

void trim()

Reduces the internal buffer to its minimal allowable size. This can free memory.

setWord

void setWord(int position,
             int word)

Replaces the word at the given position in the buffer with the specified word.

Parameters:

position -

word -

setLastWord

void setLastWord(int word)

Replaces the last word in the buffer with the specified word.

Parameters:

word -

push_back

void push_back(int word)

Appends the specified word to the end of the buffer

Parameters:

word -

push_back

void push_back(Buffer32 buffer,
               int start,
               int number)

Appends the specified buffer words to the end of the buffer.

Parameters:

buffer - the buffer

start - the position of the first word to add

number - the number of words to add

negative_push_back

void negative_push_back(Buffer32 buffer,
                        int start,
                        int number)

Same as push_back, but the words are negated.

Parameters:

buffer - the buffer

start - the position of the first word to add

number - the number of words to add

removeLastWord

void removeLastWord()

Removes the last word from the buffer

negateWord

void negateWord(int position)

Negates the word at the given position in the buffer

Parameters:

position -

andWord

void andWord(int position,
             int mask)

Replaces the word at the given position in the buffer with its bitwise-and with the given mask.

Parameters:

position -

mask -

orWord

void orWord(int position,
            int mask)

Replaces the word at the given position in the buffer with its bitwise-or with the given mask.

Parameters:

expand

void expand(int position,
            int length)

Expands the buffer by adding the given number of words at the given position. The added words may contain stale data.
