Constructor Detail

### AbstractGrailsPlugin

    public AbstractGrailsPlugin(Class pluginClass,
                                GrailsApplication application)

Method Detail

### refresh

    public void refresh()

  Description copied from interface: `GrailsPlugin`
  Refreshes this Grails plugin reloading any watched resources as necessary

  Specified by:
    `refresh` in interface `GrailsPlugin`

### doWithApplicationContext

    public abstract void doWithApplicationContext(ApplicationContext applicationContext)

  Description copied from interface: `GrailsPlugin`

  This method is called to allow the plugin to add `BeanDefinition`s to the `BeanDefinitionRegistry`.

  Specified by:
    `doWithApplicationContext` in interface `GrailsPlugin`
  Parameters:
    `applicationContext` - The Spring ApplicationContext instance

### doWithRuntimeConfiguration

    public abstract void doWithRuntimeConfiguration(RuntimeSpringConfiguration springConfig)

  Description copied from interface: `GrailsPlugin`
  Executes the plugin code that performs runtime configuration as defined in the doWithSpring closure

  Specified by:
    `doWithRuntimeConfiguration` in interface `GrailsPlugin`
  Parameters:
    `springConfig` - The RuntimeSpringConfiguration instance

### doArtefactConfiguration

    public abstract void doArtefactConfiguration()

  Description copied from interface: `GrailsPlugin`
  Called prior to the initialisation of the GrailsApplication instance to allow the registration of additonal ArtefactHandlers

  Specified by:
    `doArtefactConfiguration` in interface `GrailsPlugin`
  See Also:
    `ArtefactHandler`

### checkForChanges

    public boolean checkForChanges()

  Description copied from interface: `GrailsPlugin`
  When called this method checks for any changes to the plug-ins watched resources and reloads appropriately

  Specified by:
    `checkForChanges` in interface `GrailsPlugin`
  Returns:
    Returns true when the plug-in itself changes in some way, as oppose to plug-in resources

### doWithWebDescriptor

    public void doWithWebDescriptor(groovy.util.slurpersupport.GPathResult webXml)

  Description copied from interface: `GrailsPlugin`
  Handles processing of web.xml. The method is passed a GPathResult which is parsed by groovy.util.XmlSlurper. A plug-in can then manipulate the in-memory XML however it chooses Once all plug-ins have been processed the web.xml is then written to disk based on its in-memory form

  Specified by:
    `doWithWebDescriptor` in interface `GrailsPlugin`
  Parameters:
    `webXml` - The GPathResult representing web.xml

### getDependencyNames

    public String[] getDependencyNames()

  Specified by:
    `getDependencyNames` in interface `GrailsPlugin`
  Returns:
    The names of the plugins this plugin is dependant on

### getDependentVersion

    public String getDependentVersion(String name)

  Description copied from interface: `GrailsPlugin`
  The version of the specified dependency

  Specified by:
    `getDependentVersion` in interface `GrailsPlugin`
  Parameters:
    `name` - the name of the dependency
  Returns:
    The version

### getName

    public String getName()

  Specified by:
    `getName` in interface `GrailsPlugin`
  Returns:
    The name of the plug-in

### getVersion

    public String getVersion()

  Specified by:
    `getVersion` in interface `GrailsPlugin`
  Returns:
    The version of the plug-in

### getManager

    public GrailsPluginManager getManager()

  Description copied from interface: `GrailsPlugin`
  Retrieves the plugin manager if known, otherwise returns null

  Specified by:
    `getManager` in interface `GrailsPlugin`
  Returns:
    The PluginManager or null

### getLoadAfterNames

    public String[] getLoadAfterNames()

  Description copied from interface: `GrailsPlugin`
  Retrieves the names of plugins that this plugin should be loaded after. This differs from dependencies in that if that plugin doesn't exist this plugin will still be loaded. It is a way of enforcing plugins are loaded before, but not necessarily needed

  Specified by:
    `getLoadAfterNames` in interface `GrailsPlugin`
  Returns:
    The names of the plugins that this plugin should be loaded after

### setApplicationContext

    public void setApplicationContext(ApplicationContext applicationContext)
                               throws BeansException

  Specified by:
    `setApplicationContext` in interface `ApplicationContextAware`
  Throws:
    `BeansException`

### setManager

    public void setManager(GrailsPluginManager manager)

  Description copied from interface: `GrailsPlugin`
  Sets the plugin manager for this plugin

  Specified by:
    `setManager` in interface `GrailsPlugin`
  Parameters:
    `manager` - A GrailsPluginManager instance

### setApplication

    public void setApplication(GrailsApplication application)

  Specified by:
    `setApplication` in interface `GrailsPlugin`

### getEvictionNames

    public String[] getEvictionNames()
