Constructor Detail

DynamicDoubleArray

public DynamicDoubleArray()

Creates an empty double array, with size and capacity of 0.

public DynamicDoubleArray(int capacity)

Creates a double array of the given capacity.

DynamicDoubleArray

public DynamicDoubleArray(double... contents)

Creates a double array with the given initial contents.

Method Detail

add

public void add(double what)

Appends a single double to the end of this array.

append

public void append(double... stuff)

Appends the given doubles to the end of this array.

toDoubleArray

public double[] toDoubleArray()

contentsToString

public java.lang.String contentsToString()

Returns the contents as a String. toString() would have been a better name but is already taken.

Returns:

newArray

public void newArray(int size)

Description copied from class: DynamicArray

Allocates a new, empty array of the given size and assign it to the arrayObject property. It is assumed that subclasses will also set it to a variable of the correct class (e.g. char[]) for ease of access as well. Copying of existing contents is Dynamic by this superclass. Your code should look something like this:

 public abstract void newArray(int size) {
     arrayObject = array = new Foo[size];
 }
