Class ComponentMetadata

java.lang.Object

org.infinispan.factories.components.ComponentMetadata

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

ManageableComponentMetadata

public class ComponentMetadata
extends java.lang.Object
implements java.io.Serializable

This class contains all of the metadata and implications expressed via the Scope, SurvivesRestarts, DefaultFactoryFor, ComponentName, Inject, Start and Stop annotations. Instead of scanning for these annotations and working out dependency chains at runtime "on-demand", since Infinispan 5.1, this process now happens offline, at build-time.

When compiling Infinispan, components and their dependency chains are inspected and the information expressed by the annotations above are denormalized and a series of ComponentMetadata objects are created and persisted in the Infinispan jar.

This metadata is then read in by the ComponentMetadataRepo at runtime, and used by the ComponentRegistry and other factory-like classes to bootstrap an Infinispan node.

Also see ManageableComponentMetadata for components that also expose JMX information.

Since:

5.1
