org.infinispan.factories.components.ComponentMetadataRepo

Direct Known Subclasses:

ComponentMetadataPersister

public class ComponentMetadataRepo
extends Object

This is a repository of component metadata, which is populated when the Infinispan core jar is loaded up. Actual metadata is analyzed and persisted into the jar at build-time, taking it off the critical path.

readMetadata

public void readMetadata(URL metadataFile)
                  throws IOException,
                         ClassNotFoundException

Throws:

IOException

ClassNotFoundException

findComponentMetadata

public ComponentMetadata findComponentMetadata(Class<?> componentType)

Locates metadata for a given component type if registered. If not registered, superclasses/interfaces are consulted, until, finally, an empty instance of ComponentMetadata is returned effectively declaring that the component has no dependencies or any lifecycle methods declared.

Parameters:

componentType - component type to look for

Returns:

metadata expressed as a ComponentMetadata instance

findComponentMetadata

public ComponentMetadata findComponentMetadata(String componentName)

Locates metadata for a given component type if registered. If not registered, a null is returned.

Parameters:

componentName - name of component type to look for

Returns:

metadata expressed as a ComponentMetadata instance, or null

findFactoryForComponent

public String findFactoryForComponent(Class<?> componentType)

Locates the fully qualified class name of a factory capable of constructing an instance of

componentType

. Typically this is a factory annotated with DefaultFactoryFor.

Parameters:

componentType - component to create

Returns:

a factory, or null if not found.

initialize

public void initialize(Iterable<ModuleMetadataFileFinder> moduleMetadataFiles,
              ClassLoader cl)

Initializes this repository. The Iterable passed in should contain all ModuleMetadataFileFinder instances for all loaded Infinispan modules. Note that the core module is always loaded and need not be contained in this iterable.

Parameters:

moduleMetadataFiles - file finders to iterate through and load into the repository

injectFactoryForComponent

public void injectFactoryForComponent(Class<?> componentType,
                             Class<?> factoryType)

Inject a factory for a given component type.

Parameters:

componentType - Component type that the factory will produce

factoryType - Factory that produces the given type of components
