Method Detail

getImplementationClass

public Class<?> getImplementationClass()

Description copied from interface: ActiveDescriptor

The implementation class that should be used to generate new instances of this descriptor.

If the class returned is a Factory, then the factory is used to create instances. In this case the system will get an instance of the factory and use it to create the instances

Returns:

The class that directly implements the contract types, or the class that is the factory for an object that implements the contract types

create

public T create(ServiceHandle<?> root)

Description copied from interface: ActiveDescriptor

Creates an instance of the ActiveDescriptor. All of the Injectee's must be created prior to instantiation, and associated with the ExtendedProvider so that they can be destroyed properly

Parameters:

root - The root service handle, which can be used to associated all the PerLookup objects with this creation

Returns:

An instance of this ActiveDescriptor

dispose

public void dispose(T instance)

Description copied from interface: ActiveDescriptor

Disposes this instance. All the PerLookup objects that were created for this instance will be destroyed after this object has been destroyed

Specified by:

dispose in interface ActiveDescriptor<T>

Overrides:

dispose in class AbstractActiveDescriptor<T>

Parameters:

instance - The instance to destroy

getImplementation

public String getImplementation()

Description copied from interface: Descriptor

Returns the fully qualified class name of the implementation class. If this is a factory descriptor then this will return the fully qualified name of the class implementing the factory interface.

Specified by:

getImplementation in interface Descriptor

Overrides:

getImplementation in class DescriptorImpl

Returns:

Might return null in some cases, but will usually return the fully qualified class name of the implementation class or of the factory class for this descriptor

getInjectees

public List<Injectee> getInjectees()

Description copied from interface: ActiveDescriptor

Returns the full list of Injectees this class has. These references will be resolved prior to the class being constructed, even if these injectees are field or method injectees.

If this descriptor is describing a factory created type then this list must have zero length

Specified by:

getInjectees in interface ActiveDescriptor<T>

Overrides:

getInjectees in class AbstractActiveDescriptor<T>

Returns:

Will not return null, but may return an empty list. The set of Injectees that must be resolved before this ActiveDescriptor can be constructed
