Class EnlargingShortArray

java.lang.Object
  uka.util.EnlargingShortArray

All Implemented Interfaces:

java.io.Serializable

public final class EnlargingShortArray

extends java.lang.Object

implements java.io.Serializable

A simple wrapper class for a regular Java array. In addition to the features of built-in Java arrays, instances of this class can be enlarged either automatically by setting a value to a position that exceeds the current size() of this array, or manually be explicitely setting the size.

This class is more convenient than a ArrayList, if direct manipulation of the array size is required. In addition there are customized versions of this class for all Java basic types.

Method Detail

get

public short get(int idx)

test

public short test(int idx)

Same as get(int), except for indices larger than or equal to the array length. For these cases, test(int) returns a null value instead of throwing an exception.

set

public short set(int idx,
                 short obj)

copy

public static void copy(EnlargingShortArray src,
                        int srcIndex,
                        EnlargingShortArray dst,
                        int dstIndex,
                        int length)

add

public short add(short obj)

remove

public short remove(int idx)

pop

public short pop()

Returns the element at position size() - 1 and shrinks the size of this array by 1. This method enables a stack-like usage of this array.

permute

public void permute(Permutation permutation)

Permutes the contents of this array. The element at index n is moved to index permutation.compute(n).

setSize

public void setSize(int size)

size

public int size()

clear

public void clear()

move

public void move(int moveSrc,
                 int moveDst,
                 int moveLength)

fill

public void fill(int start,
                 int stop,
                 short value)

enlarge

private final void enlarge(int newLength)

iterator

public ShortIterator iterator()

toArray

public short[] toArray(short[] a)

toString

public java.lang.String toString()

appendTo

public void appendTo(ToString s)
