Class MapAdapter

java.lang.Object

com.codename1.properties.MapAdapter

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.
