Class ReflectedMap

java.lang.Object
  java.util.AbstractMap
      org.apache.commons.clazz.reflect.extended.ReflectedMap

All Implemented Interfaces:

Map

public class ReflectedMap
extends AbstractMap

This is an implementation of the Map interface that is based on a Mapped property. Whenever possible, it uses concrete methods on the owner of the property to manipulate the map.

Consider the following example:

      Map map = (Map)clazz.getProperty("fooMap").get(instance);
      Object value = map.get("bar");
 

If instance has a getFoo(String key) method, this code will implicitly invoke it like this: getFoo("bar"). otherwise it will obtain the whole map and extract the requested value.
