public class SimpleResourceRegistry extends Object implements ResourceRegistry
SimpleResourceRegistry is a basic implementation of a ResourceRegistry.| Modifier and Type | Class and Description |
|---|---|
protected class |
SimpleResourceRegistry.RegistryKey
Key class for a registered resource.
|
protected class |
SimpleResourceRegistry.RegistryValue
A holder for resource objects and their (optional) respective

| Modifier and Type | Method and Description |
|---|---|
void |
dispose()
Invoked when all resources owned by the implementer can safely be
released.

<R> R |
getResource(Class<R> clzResource)
Attempts to retrieve the resource that was registered with the
specified class.

<R> R |
getResource(Class<R> clzResource,
String sResourceName)
Attempts to retrieve the resource that was registered with the
specified class and name.
|
boolean |
isEmpty()
Determine if the

<R> String |
registerResource(Class<R> clzResource,
Builder<? extends R> bldrResource,
RegistrationBehavior behavior,

ResourceResolver.getResource(Class, String). |
<R> void |
unregisterResource(Class<R> clzResource,
String sResourceName)
Unregisters the resource that was previously registered of the specified class and name.

public SimpleResourceRegistry()
SimpleResourceRegistry.public boolean isEmpty()
ResourceRegistry is empty (contains no resource registrations).public void dispose()
Once disposed of the object should no longer be considered to be usable.
Note the Disposable interface is compatible with try-with-resources which will automatically invoke this method.

Note: Unregistering a resource does not cause it to be disposed, but it
does call ResourceRegistry.ResourceLifecycleObserver.onRelease(Object) if an
observer was provided at the time of registration.
