Name

expand()

Description

Increases the size of a one-dimensional array. By default, this function doubles the size of the array, but the optional newSize parameter provides precise control over the increase in size.

When using an array of objects, the data returned from the function must be cast to the object array's data type. For example: SomeClass[] items = (SomeClass[]) expand(originalArray)

Examples

int[] data = {0, 1, 3, 4};
println(data.length);  // Prints "4"
data = expand(data);
println(data.length);  // Prints "8"
data = expand(data, 512);
println(data.length);  // Prints "512"

PImage[] imgs = new PImage[32];
println(imgs.length);  // Prints "32"
imgs = (PImage[]) expand(imgs);
println(imgs.length);  // Prints "64"

Syntax

expand(list)
expand(list, newSize)

Parameters

list(boolean[], byte[], char[], int[], long[], float[], double[], String[], Object)the array to expand
newSize(int)new size for the array

Return

boolean[], byte[], char[], int[], long[], float[], double[], String[], or Object
