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

public void
clear()

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

public Buffer
clone()

Creates and returns a copy of the buffer

public void
collapse(int
the position of the buffer where to add words
position, int
the number of words to add
length)

public void
negative_push_back(Buffer
the buffer
buffer, int
the position of the first word to add
start, int

push_back(long word)

Appends the specified word to the end of the buffer

public void
push_back(Buffer
the buffer
buffer, int
the position of the first word to add
start, int
the number of words to add
number)

public void
swap(Buffer
buffer to swap with
other)

Swap the content of the buffer with another.

public void
trim()
