org.glassfish.api.deployment.MetaData

public class MetaData
extends Object

MetaData associated with a Deployer. This is used by the deployment layers to identify the special requirements of the Deployer. Supported Requirements : invalidatesClassLoader Deployer can load classes that need to be reloaded for the application to run successfully hence requiring the class loader to be flushed and reinitialized between the prepare and load phase. componentAPIs Components can use APIs that are defined outside of the component's bundle. These component's APIs (eg. Java EE APIs) must be imported by the application class loader before any application code is loaded.
