java.lang.Objectorg.directwebremoting.impl.DefaultScriptSession
public class DefaultScriptSession
An implementation of ScriptSession and RealScriptSession.
There are synchronization constraints on this class. See the field
comments of the type: GuardedBy("lock").
In addition you should note that DefaultScriptSession and
DefaultScriptSessionManager make calls to each other and you should
take care not to break any constraints in inheriting from these classes.
| Method Summary | |
|---|---|
void |
addScript(ScriptBuffer script)
Add a script to the list waiting for remote execution. |
void |
addScriptConduit(ScriptConduit conduit)
While a Marshaller is processing a request it can register a ScriptConduit with the ScriptSession to say - "pass scripts to me" |
boolean |
equals(java.lang.Object obj)
|
java.lang.Object |
getAttribute(java.lang.String name)
Returns the object bound with the specified name in this session, or null if no object is bound under the name. |
java.util.Iterator |
getAttributeNames()
Returns an Enumeration of String objects
containing the names of all the objects bound to this session. |
long |
getCreationTime()
Returns the time when this session was created, measured in milliseconds since midnight January 1, 1970 GMT. |
java.lang.String |
getId()
Returns a string containing the unique identifier assigned to this session. |
long |
getLastAccessedTime()
Returns the last time the client sent a request associated with this session, as the number of milliseconds since 1/1/1970 GMT, and marked by the time the container recieved the request. |
java.lang.Object |
getScriptLock()
Accessor for an object that we use to announce to people that might be waiting on output from this ScriptSession that there is some output ready for action. |
int |
hashCode()
|
boolean |
hasWaitingScripts()
Allows for checking to see if there is data waiting to be returned |
void |
invalidate()
Invalidates this session then unbinds any objects bound to it. |
boolean |
isInvalidated()
Checks to see if this ScriptSession has been invalidated. |
void |
removeAttribute(java.lang.String name)
Removes the object bound with the specified name from this session. |
void |
removeScriptConduit(ScriptConduit conduit)
Remove a ScriptConduit. |
void |
setAttribute(java.lang.String name,
java.lang.Object value)
Binds an object to this session, using the name specified. |
java.lang.String |
toString()
|
void |
writeScripts(ScriptConduit conduit)
We might need to send a script directly to a conduit without adding the conduit to the "open" list and then removing it directly. |

public java.lang.Object getAttribute(java.lang.String name)
ScriptSessionnull if no object is bound under the name.
getAttribute in interface ScriptSessionname - a string specifying the name of the object
public void setAttribute(java.lang.String name,
java.lang.Object value)
ScriptSessionAfter this method executes, and if the new object implements
HttpSessionBindingListener, the container calls
HttpSessionBindingListener.valueBound. The container then
notifies any HttpSessionAttributeListeners in the web
application.
If an object was already bound to this session of this name that
implements HttpSessionBindingListener, its
HttpSessionBindingListener.valueUnbound method is called.
If the value passed in is null, this has the same effect as calling
removeAttribute().
setAttribute in interface ScriptSession
name - the name to which the object is bound; cannot be nullvalue - the object to be bound
public void removeAttribute(java.lang.String name)
ScriptSessionAfter this method executes, and if the object implements
HttpSessionBindingListener, the container calls
HttpSessionBindingListener.valueUnbound. The container
then notifies any HttpSessionAttributeListeners in the web
application.
removeAttribute in interface ScriptSessionname - the name of the object to remove from this sessionpublic java.util.Iterator getAttributeNames()
ScriptSessionEnumeration of String objects
containing the names of all the objects bound to this session.
getAttributeNames in interface ScriptSessionIterator of Strings, specifying the
names of all the objects bound to this sessionpublic void invalidate()
ScriptSession
invalidate in interface ScriptSessionpublic boolean isInvalidated()
ScriptSessionThere is no similar method on HttpSession because it is
assumed that you do not store HttpSessions from one request to another,
so all sessions that you have access to will always be either valid, or
you have just invalidated it yourself so you wont need to ask. This
method makes up for the change that now ScriptSessions are accessible
from outside the normal scope.

ScriptSessionActions that your application takes, such as getting or setting a value associated with the session, do not affect the access time.

RealScriptSessionSeveral Marshallers may be active on the same page as a time and it doesn't really matter which gets the script. So ScriptSession should record all of the active ScriptConduits, but just pick one
