Nested Class Summary

static class	Factories.CastFactory<E> A simple factory which wraps another factory (ordinarily a SimpleObjectFactory) and (unsafely) casts the result to the type parameter provided.
static class	Factories.SimpleObjectFactory<E> A simple factory that creates objects of the type of the class provided, providing it has an empty constructor

Constructor Summary

Factories()

Method Summary

static <E,F> Factory<F>	cast(Factory<E> factory) Creates a factory which delegates to the provided factory and (unsafely) casts its result to the type F
static <E> Factory<E>	forClass(java.lang.Class<E> clazz) Returns a new SimpleObjectFactory which constructs objects of type clazz with its no-args constructor

forClass

public static <E> Factory<E> forClass(java.lang.Class<E> clazz)
                           throws java.lang.SecurityException,
                                  java.lang.NoSuchMethodException,

                                  java.lang.IllegalAccessException,
                                  java.lang.reflect.InvocationTargetException

Returns a new SimpleObjectFactory which constructs objects of type clazz with its no-args constructor

Parameters:

clazz - the type of object to create

Returns:

a new SimpleObjectFactory which constructs objects of type clazz with its no-args constructor

Throws:

java.lang.SecurityException - if clazz.getConstructor throws a SecurityException

java.lang.NoSuchMethodException - if a matching constructor is not found

java.lang.InstantiationException - if an object cannot be constructed using the found constructor

java.lang.IllegalAccessException - if the constructor's access is restricted

java.lang.reflect.InvocationTargetException - if the constructor throws an exception

cast

public static <E,F> Factory<F> cast(Factory<E> factory)

Creates a factory which delegates to the provided factory and (unsafely) casts its result to the type F

Type Parameters:

E - type of provided factory

F - type to unsafely cast to

Parameters:

factory - factory to delegate to

Returns:
