Class BeanInterfaceProxy

java.lang.Object

org.supercsv.util.BeanInterfaceProxy

All Implemented Interfaces:

InvocationHandler

public final class BeanInterfaceProxy
extends Object
implements InvocationHandler

This is part of the internal implementation of Super CSV.

This class creates bean instances based on an interface. This allows you, given an interface for a bean (but no implementation), to generate a bean implementation on-the-fly. This instance can then be used for fetching and storing state. It assumes all get methods starts with "get" and all set methods start with "set" and takes only 1 argument.

invoke

public Object invoke(Object proxy,
                     Method method,
                     Object[] args)

If a getter method is encountered then this method returns the stored value from the bean state (or null if the field has not been set).

If a setter method is encountered then the bean state is updated with the value of the first argument and the value is returned (to allow for method chaining)
