public void
negative_push_back(Buffer32
the buffer
buffer, int
the position of the first word to add
start, int

public void
push_back(Buffer32
the buffer
buffer, int
the position of the first word to add
start, int
the number of words to add
number)

setWord(int position, int word)

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

public int
sizeInWords()

Returns the actual size in words

public void
swap(Buffer32
buffer to swap with
other)

Swap the content of the buffer with another.

public void
trim()

Reduces the internal buffer to its minimal allowable size.
