FastIntBuffer constructor comment.

FastIntBuffer(int e)
Constructor with adjustable buffer page size of the value bfz

Method Summary

void	append(int i) Append a single int to the end of this buffer Instance
void	append(int[] int_array) Append an int array to the end of this buffer instance
void	clear() set the size of int buffer to zero, capacity untouched so int buffer can be reused without any unnecessary and additional allocation
int	getCapacity() Returns the total allocated capacity of this buffer instance.
int[]	getIntArray(int startingOffset, int len) Returns a single int array representing every int in this buffer instance
int	getPageSize() Returns the page size of this buffer instance.
int	intAt(int index) Get the int at the location specified by index.
void	modifyEntry(int index, int newValue) Assigns a new int value to location index of the buffer instance.
boolean	resize(int newSz)
int	size() Returns the total number of int values in the buffer instance
int[]	toIntArray() Returns the int array corresponding to all int values in this buffer instance
