Class ComponentMetadataRepo

java.lang.Object

org.infinispan.factories.components.ComponentMetadataRepo

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.

5.1

readMetadata

public void readMetadata(URL metadataFile)
                  throws IOException,
                         ClassNotFoundException

Throws:

IOException

findComponentMetadata

@Deprecated
public ComponentMetadata findComponentMetadata(Class<?> componentType)

Deprecated.

Since 9.4, please use findComponentMetadata(String) instead.

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

@Deprecated
public ComponentMetadata findComponentMetadata(String componentName)

Deprecated.

Since 9.4, please use findComponentMetadata(String) instead.

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

getComponentMetadata

public ComponentMetadata getComponentMetadata(Class<?> componentClass)

Look up metadata for a component class.

If the class does not have any metadata, tries to look up the metadata of its superclasses. This is needed for mocks and other classes generated at runtime.

Do not use for looking up the metadata of an interface, e.g. to determine the scope of a component that doesn't exist.

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.

findFactoryForComponent

public String findFactoryForComponent(String componentName)

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:

componentName - 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

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

Deprecated.

For testing purposes only.

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

hasFactory

public boolean hasFactory(String name)
