public abstract class DefaultIntrospectableProxy<T>
extends java.lang.Object
implements IntrospectableProxy

This is wrapper class for introspectable objects. You have to give it object to be introspected in the constructor and implement methods computing array of properties and array of children objects (computeProperties() and computeChildren()). This abstract implementation caches computed results and returns them by getProperties() and getChildren() methods.

Field Summary

private IntrospectableProxy[]	children Array of introspectable children of object represented by this proxy computed by computeChildren(object).
private T	object Object represented by this proxy.
private Property[]	properties Array of properties of object represented by this proxy computed by computeProperties(object).

Constructor Summary

DefaultIntrospectableProxy(T object)
Creates a new instance of IntrospectableProxy and bind it with given object.

Method Summary

protected abstract IntrospectableProxy[]	computeChildren(T object) Computes list of introspectable children of object to be introspected.
protected abstract Property[]	computeProperties(T object) Computes list of properties of object to be introspected.
IntrospectableProxy[]	getChildren() Returns lazy initialized list of children.
java.lang.String	getName() Returns getProxiedObject().toString(); It is strongly recomended to override this method.
Property[]	getProperties() Returns lazy initialized list of properties.
protected T	getProxiedObject() Return object proxied by this IntrospectableProxy.
