public interface IndexedSetInterface
extends IndexedGetInterface

IndexedSetInterface is an interface which defines a set(int, Object) method, commonly used for setting or storing items into indexed collections of objects.

The object must also implement the Countable interface which defines the valid range of indices. Most objects use zero based indexing and thus the valid set of indices would be 0..count()-1.

Usage

 for (int i = 0, count = x.count(); i < count; i++) {
    // for some object o, store it with the index i
    x.set(i, o);
 }

Method Detail

set

void set(int index,
         java.lang.Object object)

Set a value via an integer index. This is like an array element assignment.

Parameters:

index - the index of the item to store

Object - the object to store or associate with the index.

Throws:

java.lang.IndexOutOfBoundsException - The implementor of this interface may throw this RuntimeException if the index is not valid.
