grails.core.GrailsApplication

The main interface representing a running Grails application. This interface's main purpose is to provide a mechanism for analysing the conventions within a Grails application as well as providing metadata and information about the execution environment.
The GrailsApplication interface interfacts with {@link ArtefactHandler} instanceswhich are capable of analysing different artefact types (controllers, domain classes etc.) and introspecting the artefact conventions
Implementors of this inteface should be aware that a GrailsApplication is only initialised when the initialise() method is called. In other words GrailsApplication instances are lazily initialised by the Grails runtime. @see #initialise() @see ArtefactHandler @author Graeme Rocher @author Steven Devijver @since 0.1
