public class BeanFactory

extends java.lang.Object

Factory class to create a JavaBeans proxy that converts setter/getter access to it to get/set method invocation of a Map specified.

This class creates a proxy instance that behave as an instance of a class which implements specified interfaces. Invocations of the accessor method of the proxy instance result in get()/set() method invocations of a Map instance. So you don't have to implement accessor method, just define an interface.

If you have:

 public interface Customer {
	String getName();
	void setName(String name);
	int getId();
	void setId(int id);
 }
 

Then you can write as:

 Customer customer = (Customer) BeanFactory.newBeanInstance(Customer.class);
 customer.setId(10);
 customer.setName("Kohji Nakamura");
 int id = customer.getId();
 String name = customer.getName();
 

This factory provides some factory methods to create a proxy instance and you can use any of them.

Method Detail

newBeanInstance

public static java.lang.Object newBeanInstance(java.lang.Class ifClass)

Returns a proxy instance that implements the interface specified by ifClass. STRING_MAPPER is used as a default key mapper.

Parameters:

ifClass - A class object of an interface or a class.

Returns:

A proxy instance which implements ifClass. The proxy also implements IBaseBean

newBeanInstance

public static java.lang.Object newBeanInstance(java.lang.Class ifClass,
                                               KeyMapper keyMapper)

Returns a proxy instance that implements the interface specified by ifClass.

Parameters:

ifClass - A class object of an interface or a class.

keyMapper - a KeyMapper object. See KeyMapper.

Returns:

A proxy instance which implements ifClass. The proxy also implements IBaseBean

newBeanInstance

public static java.lang.Object newBeanInstance(java.lang.Class ifClass,
                                               KeyMapper keyMapper,
                                               java.util.Map values)

Returns a proxy instance that implements the interface specified by ifClass. Object.equals(Object obj) method invocations are delegated to the `values' object.

Parameters:

ifClass - A class object of an interface or a class.

keyMapper - a KeyMapper object. See KeyMapper.

values - A value container for the proxy instance returned by this method. Changing `values' affects the proxy, vice versa, even after the proxy creation because the `values' parameter would not be copied.

Returns:

A proxy instance which implements ifClass. The proxy also implements IBaseBean

newBeanInstance

public static java.lang.Object newBeanInstance(java.lang.Class[] ifClasses,
                                               KeyMapper keyMapper,
                                               java.util.Map values)

Returns a proxy instance that implements the interfaces specified by ifClasses. Object.equals(Object obj) method invocations are delegated to the `values' object.

Parameters:

ifClasses - Class objects of interfaces or a classes.

keyMapper - a KeyMapper object. See KeyMapper.

values - A value container for the proxy instance returned by this method. Changing `values' affects the proxy, vice versa, even after the proxy creation because the `values' parameter would not be copied.

Returns:

A proxy instance which implements ifClass. The proxy also implements IBaseBean
