java.lang.Object

org.elasticsearch.common.inject.assistedinject.FactoryProvider2<F>

All Implemented Interfaces:

java.lang.reflect.InvocationHandler, Provider<F>

public final class FactoryProvider2<F>
extends java.lang.Object
implements java.lang.reflect.InvocationHandler, Provider<F>

The newer implementation of factory provider. This implementation uses a child injector to create values.

Method Summary

Modifier and Type	Method and Description
boolean	equals(java.lang.Object o)
F	get() Provides an instance of T.
Binding<?>	getBindingFromNewInjector(java.lang.reflect.Method method, java.lang.Object[] args) Creates a child injector that binds the args, and returns the binding for the method's result.
int	hashCode()
void	initialize(Injector injector) At injector-creation time, we initialize the invocation handler.
java.lang.Object	invoke(java.lang.Object proxy, java.lang.reflect.Method method, java.lang.Object[] args) When a factory method is invoked, we create a child injector that binds all parameters, then use that to get an instance of the return type.

Method Detail

get

public F get()

Description copied from interface: Provider

Provides an instance of T. Must never return null.

Specified by:

get in interface Provider<F>

initialize

@Inject
public void initialize(Injector injector)

At injector-creation time, we initialize the invocation handler. At this time we make sure all factory methods will be able to build the target types.

getBindingFromNewInjector

public Binding<?> getBindingFromNewInjector(java.lang.reflect.Method method,
                                            java.lang.Object[] args)

Creates a child injector that binds the args, and returns the binding for the method's result.

invoke

public java.lang.Object invoke(java.lang.Object proxy,
                               java.lang.reflect.Method method,
                               java.lang.Object[] args)
                        throws java.lang.Throwable

When a factory method is invoked, we create a child injector that binds all parameters, then use that to get an instance of the return type.

Specified by:

invoke in interface java.lang.reflect.InvocationHandler

Throws:

java.lang.Throwable

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object
