org.codehaus.groovy.grails.commons
[Java] Class DefaultGrailsApplication

java.lang.Object
  groovy.lang.GroovyObjectSupport
      org.codehaus.groovy.grails.commons.DefaultGrailsApplication
All Implemented Interfaces:
GrailsApplication, org.springframework.beans.factory.BeanClassLoaderAware
public class DefaultGrailsApplication
extends groovy.lang.GroovyObjectSupport

Default implementation of the GrailsApplication interface that manages application loading, state, and artefact instances.

Upon loading this GrailsApplication will inspect each class using its registered ArtefactHandler instances. Each ArtefactHandler provides knowledge about the conventions used to establish its artefact type. For example controllers use the ControllerArtefactHandler to establish this knowledge.

New ArtefactHandler instances can be registered with the GrailsApplication thus allowing application extensibility.
