Class ArrayIntBig

java.lang.Object

org.eclipse.mat.collect.ArrayIntBig

All Implemented Interfaces:

Serializable

public final class ArrayIntBig
extends Object
implements Serializable

This class simplifies the handling of growing int[] in a very fast and memory efficient manner so that no slow collections must be used. However this class is only fast on big int[] and not on small ones where you collect just a couple of ints. The internal data is never copied during the process of growing. Only with toArray() the data is copied to the result int[].

Constructor Detail

ArrayIntBig

public ArrayIntBig()

Create an IntArray. Memory consumption is equal to creating a new ArrayList.

Method Detail

add

public final void add(int element)

Add int to IntArray.

Parameters:

element - int which should be added

addAll

public final void addAll(int[] elements)

Add int[] to IntArray.

Parameters:

elements - int[] which should be added

get

public final int get(int index)
              throws IndexOutOfBoundsException

Get int at index from IntArray.

Parameters:

index - index of int which should be returned

Returns:

int at index

Throws:

IndexOutOfBoundsException - if the index is beyond the end.

length

public final int length()

Get length of IntArray.

Returns:

length of IntArray

isEmpty

public boolean isEmpty()

Returns true if this list contains no elements.

Returns:

true if this list contains no elements.

consumption

public final long consumption()

Get memory consumption of IntArray.

Returns:

memory consumption of IntArray

toArray

public final int[] toArray()

Convert IntArray to int[]. This operation is the only one where the internal data is copied. It is directly copied to the int[] which is returned, so don't call this method more than once when done.

Returns:

int[] representing the IntArray
