Place to register default configurations.

Method Detail

hasMapping

protected boolean hasMapping(RegistrationKey key)

Parameters:

key - the key associated with the implementation class

Returns:

true if the mapping is already registered or false otherwise

getMapping

protected Class<? extends T> getMapping(RegistrationKey key)

Parameters:

key - the key associated with the implementation class to return

Returns:

the implementation class

getMappings

protected Map<RegistrationKey,Class<? extends T>> getMappings()

Returns:

the mappings indexed using a RegistrationKey.

registerImplementation

protected void registerImplementation(RegistrationKey key,
                                      Class<? extends T> implementationClass)

Register an implementation class for a given key.

Parameters:

key - the key under which to register the implementation class

implementationClass - the implementation class to register

createImplementation

protected T createImplementation(RegistrationKey key,
                                 AbstractGenericHintFactory.GenericParameters parameters,
                                 String implementationConceptName)

Generic method to create an implementation based on the registered implementation classes.

Parameters:

key - the key under which the implementation class is registered

parameters - the additional parameters necessary to create the constructor object

implementationConceptName - the name of what the implementation class is representing. This is used in exception text messages to provide message customization. For example "container", "configuration", "deployable', etc.

Returns:

the created instance

getConstructor

protected abstract Constructor<? extends T> getConstructor(Class<? extends T> implementationClass,
                                                           String hint,
                                                           AbstractGenericHintFactory.GenericParameters parameters)
                                                    throws NoSuchMethodException

Create a constructor.

Parameters:

implementationClass - implementation class for which to create the constructor

hint - the hint to differentiate this implementation class from others

parameters - additional parameters necessary to create the constructor object

Returns:

the constructor to use for creating an instance

Throws:

NoSuchMethodException - in case of error

createInstance

protected abstract T createInstance(Constructor<? extends T> constructor,
                                    String hint,
                                    AbstractGenericHintFactory.GenericParameters parameters)
                             throws Exception

Create an implementation class instance.

Parameters:

constructor - the constructor to use for creating the instance

hint - the hint to differentiate this implementation class from others

parameters - additional parameters necessary to create the instance

Returns:

the created instance

Throws:

Exception - in case of error
