Method Summary

Methods

Modifier and Type	Method and Description
int[]	array() The backing array.
void	get(int srcoff, int[] dst) Absolute bulk get copies dst.length ints from the specified offset into the slice defined by this buffer into the caller's array.
void	get(int srcoff, int[] dst, int dstoff, int dstlen) Absolute bulk get copies the specified slice of ints from this buffer into the specified slice of the caller's array.
int	getInt(int pos) Absolute get of a value at an index.
int	len() The length of the slice in the array().
int	off() The start of the slice in the array().
void	put(int pos, int[] src) Absolute bulk put copies all ints in the caller's array into this buffer starting at the specified position within the slice defined by this buffer.
void	put(int dstoff, int[] src, int srcoff, int srclen) Absolute bulk put copies the specified slice of ints from the caller's array into this buffer starting at the specified position within the slice defined by this buffer.
void	putInt(int pos, int v) Absolute put of a value at an index.
IIntArraySlice	slice(int off, int len) Return a slice of the backing buffer.
int[]	toArray() Return a copy of the data in the slice.

Method Detail

array

int[] array()

The backing array. This method DOES NOT guarantee that the backing array reference will remain constant. Some implementations use an extensible backing array and will replace the reference when the backing buffer is extended.

off

int off()

The start of the slice in the array().

len

int len()

The length of the slice in the array().

toArray

int[] toArray()

Return a copy of the data in the slice.

Returns:

A new array containing data in the slice.

slice

IIntArraySlice slice(int off,
                   int len)

Return a slice of the backing buffer. The slice will always reference the current backing array(), even when the buffer is extended and the array reference is replaced.

Parameters:

off - The starting offset into the backing buffer of the slice.

len - The length of that slice.

Returns:

The slice.

putInt

void putInt(int pos,
          int v)

Absolute put of a value at an index.

Parameters:

pos - The index.

v - The value.

getInt

int getInt(int pos)

Absolute get of a value at an index.

Parameters:

pos - The index.

Returns:

The value.

put

void put(int pos,
       int[] src)

Absolute bulk put copies all ints in the caller's array into this buffer starting at the specified position within the slice defined by this buffer.

Parameters:

pos - The starting position within the slice defined by this buffer.

src - The source data.

put

void put(int dstoff,
       int[] src,
       int srcoff,
       int srclen)

Absolute bulk put copies the specified slice of ints from the caller's array into this buffer starting at the specified position within the slice defined by this buffer.

Parameters:

dstoff - The offset into the slice to which the data will be copied.

src - The source data.

srcoff - The offset of the 1st int in the source data to be copied.

srclen - The #of ints to be copied.

get

void get(int srcoff,
       int[] dst)

Absolute bulk get copies dst.length ints from the specified offset into the slice defined by this buffer into the caller's array.

Parameters:

srcoff - The offset into the slice of the first int to be copied.

dst - The array into which the data will be copied.

get

void get(int srcoff,
       int[] dst,
       int dstoff,
       int dstlen)

Absolute bulk get copies the specified slice of ints from this buffer into the specified slice of the caller's array.

Parameters:

srcoff - The offset into the slice defined by this buffer of the first int to be copied.

dst - The array into which the data will be copied.

dstoff - The offset of the first int in that array onto which the data will be copied.

dstlen - The #of ints to be copied.
