Class MapAdapter

java.lang.Object
com.codename1.properties.MapAdapter
public abstract class MapAdapter extends java.lang.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.
