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.

  • Constructor Details

    • MapAdapter

      protected MapAdapter(Class type)

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