- Type Parameters:
T
- The type of the instances being served by the factory.
- All Known Subinterfaces:
MarshalFactory.MarshalFactoryComposite<T,
C>
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
The
MarshalFactory
defines the functionality which must be provided
in order to represent a factory for object creation depending on some
provided context and of a predefined type specified with a generic argument
(in contrast to the BeanLookupFactory
, which creates instances of an
expected type). Many alternative implementations of a MarshalFactory
may may exist which construct the instances their way.
Having factories that generic as we define it here, we are able to decouple
our business logic from any specific framework: Your business logic must not
know anything about how the instances are generated. It mainly just needs to
know how to use the MarshalFactory
. It is up to the application "end
point", i.e. a command line tool with a main-method or a web-application to
finally decide which factory to use.
Depending on the implementation used or configuration provided, the
MarshalFactory
may return singletons or dedicated separate instances
when queried for instances.

Method Details
-
toMarshaled
This method creates / retrieves an instance of the given type with the given identifier (name) constructed as defined in one to many configuration files. How the instance is configured, created or retrieved is up to the nature (implementation) of the according factory.- Type Parameters:
SRC
- The context which may influence the object being created by this factory.- Parameters:
aContext
- The context which may influence the object being created by this factory.- Returns:
- The instance being fabricated by this factory.
- Throws:
org.refcodes.exception.MarshalException
- Thrown when marshaling / serializing an object fails.
