SimplePersistentSession

public class SimplePersistentSession implements PersistentSession(Code)

This is an implementation of PersistentSession that is useful for command line usage. The code containing the controller should hand the controller an instantiated SimplePersistentSession so that the state handlers can use ControllerRequest.getSession() and simply use it without any cares in the world.

Example Usage:

 SimplePersistentSession session = new SimplePersistentSession();
 Controller con = ConfigManager.getControllerFactory().getController(
 controllerName);
 ControllerRequest params = new ControllerRequest();
 params.setUid(3);
 params.setSession(mySession);

Constructor Detail

SimplePersistentSession
public SimplePersistentSession()(Code)
	Creates new SimplePersistentSession

Method Detail

getAttribute
public Object getAttribute(String attribName)(Code)
	Retrieves the object from the request context. Parameters: attribName - the name of the object to retrieve the object or null if it doesn't exist.

getAttributeNames
public Enumeration getAttributeNames()(Code)
	Retrieves all attribute names in the request context. java.util.Enumeration

getClientAttribute
public String getClientAttribute(String attribName)(Code)
	Retrieves a value of a cookie set on the client's system. It also decrypts the value with the password you set up in your `expresso-config.xml` file. Parameters: attribName - the name of the cookie to retrieve java.lang.String the value of the cookie or null if the cookie doesn't exist.

getPeristentAttributeNames
public Enumeration getPeristentAttributeNames()(Code)
	Retrieves all attribute names from the session context. java.util.Enumeration

getPersistentAttribute
public Object getPersistentAttribute(String attribName)(Code)
	Retrieves the object from the session context. Parameters: attribName - the name of the object to retrieve the object or null if it doesn't exist.

getPersistentAttributes
public Map getPersistentAttributes()(Code)
	Retrieves the persistent attributes table. Useful if you wish to actually persisten these attributes across a command line 'session' java.util.HashMap since: Expresso 5.1

invalidate
public void invalidate()(Code)
	Clear out the session. Invalidates the entire session.

removeAttribute
public void removeAttribute(String attribName)(Code)
	Clears an attribute from the request context Parameters: attribName - the name of the attribute to remove.

removePersistentAttribute
public void removePersistentAttribute(String attribName)(Code)
	Clears an attribute from the session context Parameters: attribName - the name of the attribute to remove.

setAttribute
public void setAttribute(String attribName, Object attribValue)(Code)
	Sets an attribute that is valid for the duration of the request. Parameters: attribName - The name of the object you wish to set. Parameters: attribValue - the object you want to set.

setClientAttribute
public void setClientAttribute(String attribName, String attribValue)(Code)
	Does nothing. In a command line environment, cookies don't make sense. Parameters: attribName - the name of the attribute to Parameters: attribValue - the value of the attribute to set.

setPersistentAttribute
public void setPersistentAttribute(String attribName, Object attribValue)(Code)
	Saves an attribute to the actual session, rather than simply the response. Use this for storing objects between requests, but only use it with care since the extra memory used may bog down systems under high load. Parameters: attribName - the name of the attribute to set Parameters: attribValue - a `Serializable` java object.

setPersistentAttributes
public void setPersistentAttributes(Map newAttributes)(Code)
	Sets the persistent attributes that may have been saved across instances of command line 'session' Parameters: newAttributes - Map of attributes to set for the session.
