Constructors Summary

Methods Summary
public void	addLifecycleListener(org.apache.catalina.LifecycleListener listener) Add a lifecycle event listener to this component. param listener The listener to add lifecycle.addLifecycleListener(listener);
public void	addPropertyChangeListener(java.beans.PropertyChangeListener listener) Add a property change listener to this component. param listener a value of type 'PropertyChangeListener' support.addPropertyChangeListener(listener);
public org.apache.catalina.LifecycleListener[]	findLifecycleListeners() Get the lifecycle listeners associated with this lifecycle. If this Lifecycle has no listeners registered, a zero-length array is returned. return lifecycle.findLifecycleListeners();
public java.lang.String	getInfo() Return the info for this Store. // ------------------------------------------------------------- Properties return(info);
public org.apache.catalina.Manager	getManager() Return the Manager with which the Store is associated. return(this.manager);
public java.lang.String	getStoreName() Return the name for this Store, used for logging. return(storeName);
public void	processExpires() Called by our background reaper thread to check if Sessions saved in our store are subject of being expired. If so expire the Session and remove it from the Store. long timeNow = System.currentTimeMillis(); String[] keys = null; if(!started) { return; } try { keys = keys(); } catch (IOException e) { manager.getContainer().getLogger().error("Error getting keys", e); return; } if (manager.getContainer().getLogger().isDebugEnabled()) { manager.getContainer().getLogger().debug(getStoreName()+ ": processExpires check number of " + keys.length + " sessions" ); } for (int i = 0; i < keys.length; i++) { try { StandardSession session = (StandardSession) load(keys[i]); if (session == null) { continue; } if (session.isValid()) { continue; } if (manager.getContainer().getLogger().isDebugEnabled()) { manager.getContainer().getLogger().debug(getStoreName()+ ": processExpires expire store session " + keys[i] ); } if ( ( (PersistentManagerBase) manager).isLoaded( keys[i] )) { // recycle old backup session session.recycle(); } else { // expire swapped out session session.expire(); } remove(session.getIdInternal()); } catch (Exception e) { manager.getContainer().getLogger().error("Session: "+keys[i]+"; ", e); try { remove(keys[i]); } catch (IOException e2) { manager.getContainer().getLogger().error("Error removing key", e2); } } }
public void	removeLifecycleListener(org.apache.catalina.LifecycleListener listener) Remove a lifecycle event listener from this component. param listener The listener to add lifecycle.removeLifecycleListener(listener);
public void	removePropertyChangeListener(java.beans.PropertyChangeListener listener) Remove a property change listener from this component. param listener The listener to remove support.removePropertyChangeListener(listener);
public void	setManager(org.apache.catalina.Manager manager) Set the Manager with which this Store is associated. param manager The newly associated Manager Manager oldManager = this.manager; this.manager = manager; support.firePropertyChange("manager", oldManager, this.manager);
public void	start() Prepare for the beginning of active use of the public methods of this component. This method should be called after configure(), and before any of the public methods of the component are utilized. exception LifecycleException if this component detects a fatal error that prevents this component from being used // Validate and update our current component state if (started) throw new LifecycleException (sm.getString(getStoreName()+".alreadyStarted")); lifecycle.fireLifecycleEvent(START_EVENT, null); started = true;
public void	stop() Gracefully terminate the active use of the public methods of this component. This method should be the last one called on a given instance of this component. exception LifecycleException if this component detects a fatal error that needs to be reported // Validate and update our current component state if (!started) throw new LifecycleException (sm.getString(getStoreName()+".notStarted")); lifecycle.fireLifecycleEvent(STOP_EVENT, null); started = false;
