Detailed Description

pqPluginManager works with vtkSMPluginManager to keep track for plugins loaded/available.

It also ensures that when a new session is created, the default plugin-configuration-xmls are parsed on all processes involved to ensure that auto-load plugins are loaded. It preserves the information about plugins loaded across ParaView sessions in settings so that users can easily load previously loaded plugins.

pqPluginManager can work with multiple sessions. It maintains internal data-structures for different sessions.

Member Function Documentation

loadPluginsFromSettings() [1/2]

void pqPluginManager::loadPluginsFromSettings

(

)

Called during application initialization to load plugins from settings.

This only loads "local" plugins. pqApplicationCore calls this method explicitly after the essential components of the core have been initialized. This ensures that any plugins being loaded during startup of application have the environment setup correctly.

loadExtension()

LoadStatus pqPluginManager::loadExtension	(	pqServer *	session,
		const QString &	lib,
		QString *	errorMsg = 0,
		bool	remote = true
	)

attempt to load an extension on a server if server is NULL, extension will be loaded on client side return status on success, if NOTLOADED was returned, the error is reported If errorMsg is non-null, then errors are not reported, but the error message is put in the errorMsg string

loadExtensions()

void pqPluginManager::loadExtensions

(

pqServer *

)

attempt to load all available plugins on a server, or client plugins if NULL

loadedExtensions()

vtkPVPluginsInformation* pqPluginManager::loadedExtensions	(	pqServer *	session,
		bool	remote
	)

return all the plugins loaded on a session.

This will either returns the plugins information for local processes or server-process (for remote sessions) based on the state of remote.

pluginPaths()

QStringList pqPluginManager::pluginPaths	(	pqServer *	session,
		bool	remote
	)

Return all the paths that plugins will be searched for.

hidePlugin()

void pqPluginManager::hidePlugin	(	const QString &	lib,
		bool	remote
	)

simply adds the plugin to the ignore list, so when this class tries to serialize the plugin information, it skips the indicated plugin.

isHidden()

bool pqPluginManager::isHidden	(	const QString &	lib,
		bool	remote
	)

verifyPlugins()

bool pqPluginManager::verifyPlugins

(

pqServer *

session

)

ensures that plugins required on client and server are present on both.

Fires requiredPluginsNotLoaded() signal if any mismatch is found. Returns true is all plugin requirements are satisfied, else returns false.

pluginsUpdated

void pqPluginManager::pluginsUpdated ( )

signal

notification when plugin has been loaded.

requiredPluginsNotLoaded

void pqPluginManager::requiredPluginsNotLoaded ( pqServer *  )

signal

notification that the plugins on the client and server are mismatched.

initialize()

void pqPluginManager::initialize ( vtkSMPluginManager *  )

protected

loadPluginsFromSettings [2/2]

void pqPluginManager::loadPluginsFromSettings ( pqServer *  )

protectedslot

attempts to load the configuration for plugins for the particular server.

onServerConnected

void pqPluginManager::onServerConnected ( pqServer *  )

protectedslot

onServerDisconnected

void pqPluginManager::onServerDisconnected ( pqServer *  )

protectedslot

updatePluginLists

void pqPluginManager::updatePluginLists ( )
