Class AbstractNodeAmPlugin

java.lang.Object

org.forgerock.openam.auth.node.api.AbstractNodeAmPlugin

All Implemented Interfaces:

AmPlugin

public abstract class AbstractNodeAmPlugin
extends Object
implements AmPlugin

A convenient base class for AmPlugins that provide authentication nodes.

Note on implementing the AmPlugin.getPluginVersion() method:

Nodes extending this class and overriding the AmPlugin.getPluginVersion() may declare themselves as being of version "0.0.0" (PluginTools.DEVELOPMENT_VERSION) The framework will recognise this as meaning the plugin is still in development. This can be utilised to ensure that the SMS is installed fresh after updating a node .jar in the /WEB-INF/lib/ directory to carry over updates to the node's config. Simply shutdown AM, copy over the new .jar and startup AM.

This process will break any instance of the node (and tree containing that node) which already exists as part of a tree. Therefore, nodes whose plugins extend this class using version "0.0.0" should be tested in development trees which should be destroyed and recreated after every restart.

Once ready for release, and for subsequent upgrades, the AmPlugin.getPluginVersion() method should be overridden again to reflect the appropriate release version.

Method Detail

setPluginTools

@Inject
public void setPluginTools(PluginTools pluginTools)

Guice setter for pluginTools.

Parameters:

pluginTools - The tools.

onInstall

public void onInstall()
               throws PluginException

Description copied from interface: AmPlugin

Handle plugin installation. This method will only be called once, on first AM startup once the plugin is included in the classpath. The AmPlugin.onStartup() method will be called after this one.

Specified by:

onInstall in interface AmPlugin

Throws:

PluginException

onStartup

public void onStartup(StartupType startupType)
               throws PluginException

Description copied from interface: AmPlugin

Handle plugin startup. This method will be called every time AM starts, after AmPlugin.onInstall(), AmPlugin.onAmUpgrade(String, String) and AmPlugin.upgrade(String) have been called (if relevant).

Specified by:

onStartup in interface AmPlugin

Parameters:

startupType - The type of startup that is taking place.

Throws:

PluginException

upgrade

public void upgrade(String fromVersion)
             throws PluginException

Description copied from interface: AmPlugin

This method will be called when the version returned by AmPlugin.getPluginVersion() is higher than the version already installed. This method will be called before the AmPlugin.onStartup() method.

Specified by:

upgrade in interface AmPlugin

Parameters:

fromVersion - The old version of the plugin that has been installed.

Throws:

PluginException

getNodesByVersion

protected Map<String,Iterable<? extends Class<? extends Node>>> getNodesByVersion()

Retrieve the Map of list of node classes that the plugin is providing. The mappings returned describe which nodes have been introduced in which version of this plugin. For example:

     return ImmutableMap.of(
             "1.0.0", asList(ChoiceCollectorNode.class),
             "2.0.0", asList(SetPersistentCookieNode.class));
 

Tells that this node plugin's 1.0.0 version has introduced the ChoiceCollectorNode, the 2.0.0 version has introduced the SetPersistentCookieNode.

Returns:

The list of node classes.

getNodes

@Deprecated
protected Iterable<? extends Class<? extends Node>> getNodes()
                                                                  throws UnsupportedOperationException

Deprecated. in favour of AbstractNodeAmPlugin.getNodesByVersion()

Specify the list of node classes that the plugin is providing. These will then be installed and registered at the appropriate times in plugin lifecycle.

Returns:

The list of node classes.

Throws:

UnsupportedOperationException - if called as this method is now deprecated.
