Examples of LazyDynaBean

org.apache.commons.beanutils.LazyDynaBean
DynaBean which automatically adds properties to the DynaClass and provides Lazy List and Lazy Map features.

DynaBeans deal with three types of properties - simple, indexed and mapped and have the following get() and set() methods for each of these types:
- Simple property methods - get(name) and set(name, value)
- Indexed property methods - get(name, index) and set(name, index, value)
- Mapped property methods - get(name, key) and set(name, key, value)
Getting Property Values

Calling any of the get() methods, for a property which doesn't exist, returns null in this implementation.

Setting Simple Properties

The LazyDynaBean will automatically add a property to the DynaClass if it doesn't exist when the set(name, value) method is called.
DynaBean myBean = new LazyDynaBean();
myBean.set("myProperty", "myValue");

Setting Indexed Properties

If the property doesn't exist, the LazyDynaBean will automatically add a property with an ArrayList type to the DynaClass when the set(name, index, value) method is called. It will also instantiate a new ArrayList and automatically grow the List so that it is big enough to accomodate the index being set. ArrayList is the default indexed property that LazyDynaBean uses but this can be easily changed by overriding the defaultIndexedProperty(name) method.
DynaBean myBean = new LazyDynaBean();
myBean.set("myIndexedProperty", 0, "myValue1");
myBean.set("myIndexedProperty", 1, "myValue2");

If the indexed property does exist in the DynaClass but is set to null in the LazyDynaBean, then it will instantiate a new List or Array as specified by the property's type in the DynaClass and automatically grow the List or Array so that it is big enough to accomodate the index being set.
DynaBean myBean = new LazyDynaBean();
MutableDynaClass myClass = (MutableDynaClass)myBean.getDynaClass();
myClass.add("myIndexedProperty", int[].class);
myBean.set("myIndexedProperty", 0, new Integer(10));
myBean.set("myIndexedProperty", 1, new Integer(20));

Setting Mapped Properties

If the property doesn't exist, the LazyDynaBean will automatically add a property with a HashMap type to the DynaClass and instantiate a new HashMap in the DynaBean when the set(name, key, value) method is called. HashMap is the default mapped property that LazyDynaBean uses but this can be easily changed by overriding the defaultMappedProperty(name) method.
DynaBean myBean = new LazyDynaBean();
myBean.set("myMappedProperty", "myKey", "myValue");

If the mapped property does exist in the DynaClass but is set to null in the LazyDynaBean, then it will instantiate a new Map as specified by the property's type in the DynaClass.
DynaBean myBean = new LazyDynaBean();
MutableDynaClass myClass = (MutableDynaClass)myBean.getDynaClass();
myClass.add("myMappedProperty", TreeMap.class);
myBean.set("myMappedProperty", "myKey", "myValue");

Restricted DynaClass

MutableDynaClass have a facility to restrict the DynaClass so that its properties cannot be modified. If the MutableDynaClass is restricted then calling any of the set() methods for a property which doesn't exist will result in a IllegalArgumentException being thrown.
