Method Detail

getComponentInstance

public T getComponentInstance()

Description copied from interface: ComponentAdapter

Retrieve the component instance. This method will usually create a new instance each time it is called, but that is not required.

Returns:

the component instance.

getScope

public Class<? extends Annotation> getScope()

Gives the scope of the adapter

createInstance

protected T createInstance(javax.enterprise.context.spi.Context ctx)

isSingleton

public boolean isSingleton()

Indicates whether or not this adapter is a singleton

getSetMethod

protected static Method getSetMethod(Class<?> clazz,
                                     String name,
                                     Class<?> pluginClass)

Finds the best "set method" according to the given method name and type of plugin

Parameters:

clazz - the Class of the target component

name - the name of the method

pluginClass - the Class of the plugin

Returns:

the "set method" corresponding to the given context

create

protected T create()

Must be used to create Singleton or Prototype only

create

public T create(javax.enterprise.context.spi.CreationalContext<T> creationalContext)

Specified by:

create in interface javax.enterprise.context.spi.Contextual<T>

destroy

public void destroy(T instance,
                    javax.enterprise.context.spi.CreationalContext<T> creationalContext)

Specified by:

destroy in interface javax.enterprise.context.spi.Contextual<T>

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

getId

public String getId()

Specified by:

getId in interface javax.enterprise.inject.spi.PassivationCapable

manageScope

protected boolean manageScope(boolean isSingleton,
                              boolean isInitialized,
                              boolean hasInjectableConstructor,
                              boolean isInjectPresent)

Defines the scope of the component

Returns:

true if the component is considered as a singleton, false otherwise.
