Class NamedLockFactoryAdapterFactoryImpl

java.lang.Object

org.eclipse.aether.internal.impl.synccontext.named.NamedLockFactoryAdapterFactoryImpl

All Implemented Interfaces:

NamedLockFactoryAdapterFactory, Service

@Singleton
@Named
public class NamedLockFactoryAdapterFactoryImpl
extends Object
implements NamedLockFactoryAdapterFactory, Service

Default implementation of NamedLockFactoryAdapterFactory. This implementation creates new instances of the adapter on every call. In turn, on shutdown, it will shut down all existing named lock factories. This is merely for simplicity, to not have to track "used" named lock factories, while it exposes all available named lock factories to callers.

Most members and methods of this class are protected. It is meant to be extended in case of need to customize its behavior. An exception from this are private static methods, mostly meant to provide out of the box defaults and to be used when no Eclipse Sisu component container is used.

Since:

1.9.1

Method Details

initService

public void initService(ServiceLocator locator)

Description copied from interface: Service

Provides the opportunity to initialize this service and to acquire other services for its operation from the locator. A service must not save the reference to the provided service locator.

Specified by:

initService in interface Service

Parameters:

locator - The service locator, must not be null.

getAdapter

public NamedLockFactoryAdapter getAdapter(RepositorySystemSession session)

Current implementation simply delegates to createAdapter(RepositorySystemSession).

Specified by:

getAdapter in interface NamedLockFactoryAdapterFactory

createAdapter

protected NamedLockFactoryAdapter createAdapter(RepositorySystemSession session)

Creates a new adapter instance, never returns null.

getFactoryName

protected String getFactoryName(RepositorySystemSession session)

Returns the selected (user configured or default) named lock factory name, never null.

getDefaultFactoryName

protected String getDefaultFactoryName()

Returns the default named lock factory name, never null.

getNameMapperName

protected String getNameMapperName(RepositorySystemSession session)

Returns the selected (user configured or default) name mapper name, never null.

getDefaultNameMapperName

protected String getDefaultNameMapperName()

Returns the default name mapper name, never null.

selectFactory

protected NamedLockFactory selectFactory(String factoryName)

Selects a named lock factory, never returns null.

selectNameMapper

protected NameMapper selectNameMapper(String nameMapperName)

Selects a name mapper, never returns null.

shutdown

protected void shutdown()

To be invoked on repository system shut down. This method will shut down each NamedLockFactory.
