Examples of org.glassfish.api.admin.AdminCommand

org.glassfish.api.admin.AdminCommand

This is an admin command interface, command implementations have to be stateless and should also have a {@link org.jvnet.hk2.component.Scope}value of {@link org.jvnet.hk2.component.PerLookup}
Command implementations should use the {@link org.glassfish.api.Param}annotation to annotate the command parameters. Command implementations are normal services and are therefore following the normal hk2 service lifecycle and injection features.
Internationalization can be provided by using the {@link org.glassfish.api.I18n}} annotation. Each parameter declaration can also be annotated with an {@link org.glassfish.api.I18n} annotation to point to the parameter .
By default, if an {@link org.glassfish.api.I18n} is used to annotate implementations,the value of the annotation will be used as follow to lookup strings in the module's local strings properties files. key provide a short description of the command role and expected output key.usagetext [optional] if not provided, usage text will be calculated based on parameters declaration key.paramName [optional] provide a description for the parameter "paramName", it can be overriden by annotating the @Param annotated field/method with a {@link org.glassfish.api.I18n} @author Jerome Dochez
