| FactoryCreator | | public class FactoryCreator extends FactoryRegistry (Code) | | A
capable to creates factories if no appropriate
instance was found in the registry.
This class maintains a cache of previously created factories, as
. Calls to
FactoryCreator.getServiceProvider getServiceProvider first check if a
previously created factory can fit.

| Method Summary | |
| protected Object | createServiceProvider(Class category, Class implementation, Hints hints)
Creates a new instance of the specified factory using the specified hints.
The default implementation tries to instantiate the given implementation class
using the first of the following constructor found:
- Constructor with a single
Hints argument.
- No-argument constructor.
Parameters:
category - The category to instantiate.
Parameters:
implementation - The factory class to instantiate.
Parameters:
hints - The implementation hints. | | final List | getCachedProviders(Class category)
Returns the providers available in the cache. | | public Object | getServiceProvider(Class category, Filter filter, Hints hints, Hints.Key key)
Returns a provider for the specified category, using the specified map of hints (if any).
If a provider matching the requirements is found in the registry, it is returned. |
| FactoryCreator | | public FactoryCreator(Class category)(Code) | | Constructs a new registry for the specified category.
Parameters:
category - The single category.
since:
2.4 |
| FactoryCreator | | public FactoryCreator(Class[] categories)(Code) | | Constructs a new registry for the specified categories.
Parameters:
categories - The categories.
since:
2.4 |
| FactoryCreator | | public FactoryCreator(Collection categories)(Code) | | Constructs a new registry for the specified categories.
Parameters:
categories - The categories. |
| createServiceProvider | | protected Object createServiceProvider(Class category, Class implementation, Hints hints) throws FactoryRegistryException(Code) | | Creates a new instance of the specified factory using the specified hints.
The default implementation tries to instantiate the given implementation class
using the first of the following constructor found:
- Constructor with a single
Hints argument.
- No-argument constructor.
Parameters:
category - The category to instantiate.
Parameters:
implementation - The factory class to instantiate.
Parameters:
hints - The implementation hints. The factory.
throws:
FactoryRegistryException - if the factory creation failed. |
| getServiceProvider | | public Object getServiceProvider(Class category, Filter filter, Hints hints, Hints.Key key) throws FactoryRegistryException(Code) | | Returns a provider for the specified category, using the specified map of hints (if any).
If a provider matching the requirements is found in the registry, it is returned. Otherwise,
a new provider is created and returned. This creation step is the only difference between
this method and the
.
Parameters:
category - The category to look for.
Parameters:
filter - An optional filter, or null if none.
Parameters:
hints - A , or null if none.
Parameters:
key - The key to use for looking for a user-provided instance in the hints, or null if none. A factory for the specified category and hints (never null ).
throws:
FactoryNotFoundException - if no factory was found, and the specified hints don'tprovide suffisient information for creating a new factory.
throws:
FactoryRegistryException - if the factory can't be created for some other reason. |
