public abstract class MapAdapter extends Object
Instances of this class adapt an arbitrary object type so a property can appear differently when it's placed into a Map or initialized from a Map. This impacts JSON generation too as it relies heavily on the process of transforming elements to/from maps.
To use this class create a new subclass of it and override the appropriate methods.

MapAdapter(Class type)
By default subclasses should target a specific type but this can be
further narrowed by overriding
useAdapterFor(com.codename1.properties.PropertyBase). |
