All Implemented Interfaces:

Iterable, Collection, List

public class RepeaterAsList
extends AbstractList

A List view of a Repeater, each element of the list being a Map wrapping a repeater row, as defined by ContainerWidgetAsMap.

This implementation of list supports all methods, with the following restrictions:

• values stored in the list must be Maps, that will be used with ContainerWidgetAsMap.putAll(Map) on the Map representation of the repeater rows,
• operations that involve testing equality with the list contents (e.g. contains(Object)) will not function properly, the Map wrapping the rows being created on demand.

Since:

2.1.8

Parameters:

repeater - the repeater to wrap

keysToLowerCase - should we convert input keys to lower case?
