java.lang.Object

org.atmosphere.inject.InjectableObjectFactory

All Implemented Interfaces:

AtmosphereObjectFactory<Injectable<?>>, AtmosphereConfigAware

public class InjectableObjectFactory
extends java.lang.Object
implements AtmosphereObjectFactory<Injectable<?>>

Support injection of Atmosphere's Internal object using AtmosphereConfig,AtmosphereFramework,org.atmosphere.cpr.BroadcasterFactory, {@link org.atmosphere.cpr.AtmosphereResourceFactory } ,{@link org.atmosphere.cpr.DefaultMetaBroadcaster } and {@link org.atmosphere.cpr.AtmosphereResourceSessionFactory } and classes implementing the {@link Injectable} defined inside META_INF/services/org.atmosphere.inject.Inject

Method Detail

configure

public void configure(AtmosphereConfig config)

Description copied from interface: AtmosphereConfigAware

Configure an AtmosphereFramework object.

Specified by:

configure in interface AtmosphereConfigAware

Parameters:

config - AtmosphereConfig

newClassInstance

public <T,U extends T> U newClassInstance(java.lang.Class<T> classType,
                                          java.lang.Class<U> defaultType)
                                   throws java.lang.InstantiationException,
                                          java.lang.IllegalAccessException

Description copied from interface: AtmosphereObjectFactory

Delegate the creation of Object to the underlying object provider like Spring, Guice, etc. When creating a class, it is important to check if the class can be configured via its implementation of the AtmosphereConfigAware. AtmosphereConfigAware.configure(AtmosphereConfig) should be called in that case.

Specified by:

newClassInstance in interface AtmosphereObjectFactory<Injectable<?>>

Parameters:

classType - The class' type to be created

defaultType - a class to be created @return an instance of T

Throws:

java.lang.InstantiationException

java.lang.IllegalAccessException

postConstructExecution

public <U> void postConstructExecution(U instance,
                                       java.lang.Class<U> defaultType)
                                throws java.lang.IllegalAccessException

Execute method.

Type Parameters:

U -

Parameters:

instance - the requested object.

defaultType - the type of the requested object

Throws:

java.lang.IllegalAccessException

injectAtmosphereInternalObject

public <U> void injectAtmosphereInternalObject(U instance,
                                               java.lang.Class<U> defaultType,
                                               AtmosphereFramework framework)
                                        throws java.lang.IllegalAccessException

Type Parameters:

U -

Parameters:

instance - the requested object.

defaultType - the type of the requested object

framework - the AtmosphereFramework

Throws:

java.lang.IllegalAccessException

allowInjectionOf

public AtmosphereObjectFactory allowInjectionOf(Injectable<?> injectable)

Description copied from interface: AtmosphereObjectFactory

Pass information to the underlying Dependency Injection Implementation

Specified by:

allowInjectionOf in interface AtmosphereObjectFactory<Injectable<?>>

Parameters:

injectable - an Z

Returns:

this

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getInjectable

public <U> U getInjectable(java.lang.Class<U> u)

Use this method to retrieve available Injectable. This method is for application that inject their own Injectable and needs already constructed classes.

Type Parameters:

U - the type

Parameters:

u - the class

Returns:

the class if exists, null if not
