exception:
java.lang.IllegalArgumentException - if name is null. |

all the objects bound to this session in the given scope, or an
empty Enumeration if no attributes are available in the
given scope.
Parameters:
scope - session scope of the attribute names an Enumeration of String objects specifying thenames of all the objects bound tothis session, or an empty Enumeration if no attributes are available in the given scope.
exception:
java.lang.IllegalStateException - if this method is called on aninvalidated session |
| getCreationTime | | public long getCreationTime()(Code) | | Returns the time when this session was created, measured in
milliseconds since midnight January 1, 1970 GMT.
a long specifyingwhen this session was created,expressed in milliseconds since 1/1/1970 GMT
exception:
java.lang.IllegalStateException - if this method is called on aninvalidated session |
| getId | | public String getId()(Code) | | Returns a string containing the unique identifier assigned to this session.
a string specifying the identifierassigned to this session |
| getLastAccessedTime | | public long getLastAccessedTime()(Code) | | Returns the last time the client sent a request associated with this session,
as the number of milliseconds since midnight January 1, 1970 GMT.
Actions that your portlet takes, such as getting or setting
a value associated with the session, do not affect the access
time.
a longrepresenting the last time the client sent a request associatedwith this session, expressed in milliseconds since 1/1/1970 GMT |
| getMaxInactiveInterval | | public int getMaxInactiveInterval()(Code) | | Returns the maximum time interval, in seconds, for which the portlet container
keeps this session open between client accesses. After this interval,
the portlet container invalidates the session. The maximum time
interval can be set
with the setMaxInactiveInterval method.
A negative time indicates the session should never timeout.
an integer specifying the number ofseconds this session remains openbetween client requests

| getPortletContext | | public PortletContext getPortletContext()(Code) | | Returns the portlet application context associated with this session.
the portlet application context |
| invalidate | | public void invalidate()(Code) | | Invalidates this session (all scopes) and unbinds any objects bound to it.
Invalidating the portlet session will result in invalidating the underlying
HttpSession
exception:
java.lang.IllegalStateException - if this method is called on asession which has already been invalidated |
| isNew | | public boolean isNew()(Code) | | Returns true if the client does not yet know about the session or
if the client chooses not to join the session.
true if the server has created a session, but the client has not joined yet.
exception:
java.lang.IllegalStateException - if this method is called on asession which has already been invalidated |
| removeAttribute | | public void removeAttribute(String name) throws IllegalArgumentException(Code) | | Removes the object bound with the specified name under
the PORTLET_SCOPE from
this session. If the session does not have an object
bound with the specified name, this method does nothing.
Parameters:
name - the name of the object to beremoved from this session in the PORTLET_SCOPE.
exception:
java.lang.IllegalStateException - if this method is called on asession which has been invalidated
exception:
java.lang.IllegalArgumentException - if name is null. |
| removeAttribute | | public void removeAttribute(String name, int scope) throws IllegalArgumentException(Code) | | Removes the object bound with the specified name and the given scope from
this session. If the session does not have an object
bound with the specified name, this method does nothing.
Parameters:
name - the name of the object to beremoved from this session
Parameters:
scope - session scope of this attribute
exception:
java.lang.IllegalStateException - if this method is called on asession which has been invalidated
exception:
java.lang.IllegalArgumentException - if name is null. |
| setAttribute | | public void setAttribute(String name, Object value) throws IllegalArgumentException(Code) | | Binds an object to this session under the PORTLET_SCOPE, using the name specified.
If an object of the same name in this scope is already bound to the session,
that object is replaced.
After this method has been executed, 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
that implements HttpSessionBindingListener, its
HttpSessionBindingListener.valueUnbound method is called.
If the value is null, this has the same effect as calling
removeAttribute().
Parameters:
name - the name to which the object is bound underthe PORTLET_SCOPE;this cannot be null.
Parameters:
value - the object to be bound
exception:
java.lang.IllegalStateException - if this method is called on asession which has been invalidated
exception:
java.lang.IllegalArgumentException - if name is null. |
| setAttribute | | public void setAttribute(String name, Object value, int scope) throws IllegalArgumentException(Code) | | Binds an object to this session in the given scope, using the name specified.
If an object of the same name in this scope is already bound to the session,
that object is replaced.
After this method has been executed, 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
that implements HttpSessionBindingListener, its
HttpSessionBindingListener.valueUnbound method is called.
If the value is null, this has the same effect as calling
removeAttribute().
Parameters:
name - the name to which the object is bound;this cannot be null.
Parameters:
value - the object to be bound
Parameters:
scope - session scope of this attribute
exception:
java.lang.IllegalStateException - if this method is called on asession which has been invalidated
exception:
java.lang.IllegalArgumentException - if name is null. |
| setMaxInactiveInterval | | public void setMaxInactiveInterval(int interval)(Code) | | Specifies the time, in seconds, between client requests, before the
portlet container invalidates this session. A negative time
indicates the session should never timeout.
Parameters:
interval - An integer specifying the numberof seconds |
