Class DefaultBeanWrapperFactory

java.lang.Object

net.sf.juffrou.reflect.DefaultBeanWrapperFactory

All Implemented Interfaces:

BeanWrapperFactory

public class DefaultBeanWrapperFactory
extends Object
implements BeanWrapperFactory

This class is responsible for creating and caching BeanWrapperContexts.

A BeanWrapper uses the same BeanWrapperFactory to create the BeanWrapperContexts for its nested BeanWrappers. BeanWrapperFactory can also be used as an umbrella to create BeanWrappers in a more performant way as it caches the introspection information and re-uses it whenever possible.

If the BeanWrapperContext is not in cache then creates a new one.

Specified by:

getBeanWrapperContext in interface BeanWrapperFactory

Parameters:

clazz - the bean class to inspect

Returns:

a BeanWrapperContext with introspection information about the specified class.

getBeanWrapperContext

public BeanWrapperContext getBeanWrapperContext(Class clazz,
                                       Type... types)

Retrieves a BeanWrapperContext for a parameterized (generic) java bean class.

If the BeanWrapperContext is not in cache then creates a new one.

Specified by:

getBeanWrapperContext in interface BeanWrapperFactory

Parameters:

clazz - the generic bean class to inspect.

types - the parameters that defined the generic bean class.

Returns:

a BeanWrapperContext with introspection information about the specified class.

getBeanWrapper

public JuffrouBeanWrapper getBeanWrapper(Class clazz)

Construct a bean wrapper around a class.

Bean instances will be instances of that class and will be created only when necessary.
Try to use a cached BeanWrapperContext to save introspection time.

Specified by:

getBeanWrapper in interface BeanWrapperFactory

Parameters:

clazz - class to instantiate the wrapped bean

getBeanWrapper

public JuffrouBeanWrapper getBeanWrapper(Object instance)

Construct a bean wrapper around an existing bean instance.

Will try to use a cached BeanWrapperContext to save introspection time.

Specified by:

getBeanWrapper in interface BeanWrapperFactory

Parameters:

instance - the bean object to be wrapped

getBeanInstanceBuilder

public BeanInstanceBuilder getBeanInstanceBuilder()

Specified by:

getBeanInstanceBuilder in interface BeanWrapperFactory
