MapChoice (container-search 7.552.18 API)

java.lang.Object
- com.yahoo.component.provider.FreezableClass
- - com.yahoo.search.pagetemplates.model.AbstractChoice
  - - com.yahoo.search.pagetemplates.model.MapChoice

All Implemented Interfaces:

com.yahoo.component.provider.Freezable, PageElement
```
public class MapChoice
extends AbstractChoice
```
A choice between different possible mapping functions of a set of values to a set of placeholder ids. A resolution of this choice consists of choosing a unique value for each placeholder id (hence a map choice is valid iff there are at least as many values as placeholder ids).
Each unique set of mappings (pairs) from values to placeholder ids is a separate possible alternative of this choice. The alternatives are not listed explicitly but are generated as needed.
