Constructor Detail

DefaultGrailsPlugin

public DefaultGrailsPlugin(Class pluginClass,
                           Resource resource,
                           GrailsApplication application)

DefaultGrailsPlugin

public DefaultGrailsPlugin(Class pluginClass,
                           GrailsApplication application)

Method Detail

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

Overrides:

getLoadAfterNames in class AbstractGrailsPlugin

Returns:

The names of the plugins that this plugin should be loaded after

getResolver

public PathMatchingResourcePatternResolver getResolver()

Returns:

the resolver

getParentCtx

public ApplicationContext getParentCtx()

beans

public BeanBuilder beans(groovy.lang.Closure closure)

doWithApplicationContext

public void doWithApplicationContext(ApplicationContext applicationContext)

Description copied from interface: GrailsPlugin

This method is called to allow the plugin to add BeanDefinitions to the BeanDefinitionRegistry.

Specified by:

doWithApplicationContext in interface GrailsPlugin

Specified by:

doWithApplicationContext in class AbstractGrailsPlugin

Parameters:

applicationContext - The Spring ApplicationContext instance

doWithRuntimeConfiguration

public 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

Specified by:

doWithRuntimeConfiguration in class AbstractGrailsPlugin

Parameters:

springConfig - The RuntimeSpringConfiguration instance

getName

public String getName()

Specified by:

getName in interface GrailsPlugin

Overrides:

getName in class AbstractGrailsPlugin

Returns:

The name of the plug-in

getVersion

public String getVersion()

Specified by:

getVersion in interface GrailsPlugin

Overrides:

getVersion in class AbstractGrailsPlugin

Returns:

The version of the plug-in

getDependencyNames

public String[] getDependencyNames()

Specified by:

getDependencyNames in interface GrailsPlugin

Overrides:

getDependencyNames in class AbstractGrailsPlugin

Returns:

The names of the plugins this plugin is dependant on

getWatchedResources

public Resource[] getWatchedResources()

Returns:

the watchedResources

getDependentVersion

public String getDependentVersion(String name)

Description copied from interface: GrailsPlugin

The version of the specified dependency

Specified by:

getDependentVersion in interface GrailsPlugin

Overrides:

getDependentVersion in class AbstractGrailsPlugin

Parameters:

name - the name of the dependency

Returns:

The version

toString

public String toString()

Overrides:

toString in class Object

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

Overrides:

doWithWebDescriptor in class AbstractGrailsPlugin

Parameters:

webXml - The GPathResult representing web.xml

checkForChanges

public boolean checkForChanges()

Monitors the plugin resources defined in the watchResources property for changes and fires onChange events by calling an onChange closure defined in the plugin (if it exists)

Specified by:

checkForChanges in interface GrailsPlugin

Overrides:

checkForChanges in class AbstractGrailsPlugin

Returns:

Returns true when the plug-in itself changes in some way, as oppose to plug-in resources

fireModifiedEvent

protected void fireModifiedEvent(Resource resource,
                                 GrailsPlugin plugin)

restartContainer

public void restartContainer()

setWatchedResources

public void setWatchedResources(Resource[] watchedResources)
                         throws IOException
