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

getFileSystemName

public String getFileSystemName()

Description copied from interface: GrailsPlugin

Returns the name of the plugin as represented in the file system including the version. For example TagLibGrailsPlugin would result in "tag-lib-0.1"

Specified by:

getFileSystemName in interface GrailsPlugin

Returns:

The file system representation of the plugin name

getFileSystemShortName

public String getFileSystemShortName()

Description copied from interface: GrailsPlugin

Returns the name of the plugin as represented on the file system without the version. For example TagLibGrailsPlugin would result in "tag-lib"

Specified by:

getFileSystemShortName in interface GrailsPlugin

Returns:

The file system name

getPluginClass

public Class<?> getPluginClass()

Description copied from interface: GrailsPlugin

Returns the underlying class that represents this plugin

Specified by:

getPluginClass in interface GrailsPlugin

Returns:

The plugin class

isBasePlugin

public boolean isBasePlugin()

Description copied from interface: GrailsPlugin

Returns whether this plugin is loaded from the current plugin. In other words when you execute grails run-app from a plugin project the plugin project's *GrailsPlugin.groovy file represents the base plugin and this method will return true for this plugin

Specified by:

isBasePlugin in interface GrailsPlugin

Returns:

True if it is the base plugin

setBasePlugin

public void setBasePlugin(boolean isBase)

Description copied from interface: GrailsPlugin

Sets whether this plugin is the base plugin

Specified by:

setBasePlugin in interface GrailsPlugin

Parameters:

isBase - True if is

See Also:

GrailsPlugin.isBasePlugin()

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 GrailsPluginInfo

Returns:

The name of the plug-in

getVersion

public String getVersion()

Specified by:

getVersion in interface GrailsPluginInfo

Returns:

The version of the plug-in

getPluginPath

public String getPluginPath()

Description copied from interface: GrailsPlugin

Returns the path of the plug-in

Specified by:

getPluginPath in interface GrailsPlugin

Returns:

A String that makes up the path to the plug-in in the format /plugins/PLUGIN_NAME-PLUGIN_VERSION

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

getLoadBeforeNames

public String[] getLoadBeforeNames()

Description copied from interface: GrailsPlugin

Retrieves the names of plugins that this plugin should be loaded before. As with getLoadAfterNames() it is not a requirement that the specified plugins exist

Specified by:

getLoadBeforeNames in interface GrailsPlugin

Returns:

The names of the plugins that this plugin should load before

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
