public class Plugin
extends BaseWrappingResourceLoader

Essentially a Plugin is a specialized ResourceLoader with a custom classloader and attached configuration.

addPluginListener

public void addPluginListener(PluginListener pluginListener)

removePluginListener

public void removePluginListener(PluginListener pluginListener)

startPluginListeners

protected void startPluginListeners()

stopPluginListeners

protected void stopPluginListeners()

If we fail to stop a plugin listener, try the next one but don't propogate any exceptions out of this method. Otherwise the plugin ends up dying and can't be reloaded from a hot deploy.

isSupressStartupFailure

public boolean isSupressStartupFailure()

public void setSupressStartupFailure(boolean supressStartupFailure)

bindThread

public void bindThread()

unbindThread

public void unbindThread()

getConfig

public Config getConfig()

toString

public String toString()

Overrides:
