public interface MutableIndexedContainerReflector
extends IndexedContainerReflector

A reflector for an indexed structure that allows modification of an element at a given index. Most objects that are indexed are also "mutably indexed", if you will, but some are not. Most notably, you can't change an element at a specified index of a SortedSet because by virtue of adding something new to the set you may be changing the indices of the elements.

Method Detail

set

java.lang.Object set(java.lang.Object container,
                     int index,
                     java.lang.Object propertyValue)
                     throws ReflectionException

Sets the element at the specified index. Valid indexes range between 0 and one less than the container object's size, inclusive.

Parameters:

container - the container object

index - a number indiciating which element should be set

propertyValue - the value to be set

Returns:

the element previously at the specified position

Throws:

ReflectionException - if container is null or
index is not a valid index for the given container object or
the object at the specified index could not be set for some reason
