public class IntArray
extends Object

This class implements an facade for int[]. Size of array is fixed and cannot be changed after it is created.

Constructor Summary

IntArray(int length)
Creates a new int[] with specified length.

Method Summary

IntArray	clear(int fill) Fills the whole array with specified integer.
int	length() Returns the length of this array.
int	operator_get(int index) Returns the integer at specified index.
int	operator_set(int index, int value) Sets the integer at specified index.
IntArray	set$(int offset) Sets multiple integers at once, starting from specified offset.
IntArray	setLength(int length) Creates a new array with specified length.

Constructor Detail

IntArray

public IntArray(int length)

Creates a new int[] with specified length.

Parameters:

length - Length of array, must be >= 0

Method Detail

operator_get

public int operator_get(int index)

Returns the integer at specified index.

Parameters:

index - Index to array

Returns:

integer at specified index

operator_set

public int operator_set(int index,
                        int value)

Sets the integer at specified index.

Parameters:

index - Index to array

value - New value for index

Returns:

value parameter

setLength

public IntArray setLength(int length)

Creates a new array with specified length. Initial contents are duplicated from this array. If new length is greater than length of this array the new indices are filled with zeros.

Parameters:

length - New length of array

Returns:

new IntArray instance

length

public int length()

Returns the length of this array.

Returns:

length of array

clear

public IntArray clear(int fill)

Fills the whole array with specified integer.

Parameters:

fill - Filler integer

Returns:

this IntArray

2.0.0

set$

public IntArray set$(int offset)

Sets multiple integers at once, starting from specified offset. Note that all the arguments must result integers - in some situation the forced cast is needed. Arguments that are out of array range are silently ignored.

 int a = ...;
 IntArray matrix = 
   new IntArray(9).set(0,, -a-1, -a, -a+1, 
                             -1,  0,    1,
                            a-1,  a,  a+1);
 

Parameters:

offset - Offset to start setting from

Returns:

this IntArray
