Returns an Enumeration of String objects containing the names of all the objects bound to this session.
an Enumeration of String objects specifying the names of all the objects bound to this session
IllegalStateException if this method is called on an invalidated session
Returns the time when this session was created, measured in milliseconds since midnight January 1, 1970 GMT.
a long specifying when this session was created, expressed in milliseconds since 1/1/1970 GMT
IllegalStateException if this method is called on an invalidated session
Returns the last time the client sent a request associated with this session, as the number of milliseconds since midnight January 1, 1970 GMT, and marked by the time the container received the request.
Actions that your application takes, such as getting or setting a value associated with the session, do not affect the access time.
a long representing the last time the client sent a request associated with this session, expressed in milliseconds since 1/1/1970 GMT
IllegalStateException if this method is called on an invalidated session
Returns the maximum time interval, in seconds, that the servlet container will keep this session open between client accesses. After this interval, the servlet container will invalidate the session. The maximum time interval can be set with the setMaxInactiveInterval method.
A return value of zero or less indicates that the session will never timeout.
an integer specifying the number of seconds this session remains open between client requests
#setMaxInactiveInterval
Returns true if the client does not yet know about the session or if the client chooses not to join the session. For example, if the server used only cookie-based sessions, and the client had disabled the use of cookies, then a session would be new on each request.
true if the server has created a session, but the client has not yet joined
IllegalStateException if this method is called on an already invalidated session
Removes the object bound with the specified name from this session. If the session does not have an object bound with the specified name, this method does nothing.
After this method executes, and if the object implements HttpSessionBindingListener, the container calls HttpSessionBindingListener.valueUnbound. The container then notifies any HttpSessionAttributeListeners in the web application.
the name of the object to remove from this session
IllegalStateException if this method is called on an invalidated session
Binds an object to this session, using the name specified. If an object of the same name is already bound to the session, the object is replaced.
After 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().
the name to which the object is bound; cannot be null
the object to be bound
IllegalStateException if this method is called on an invalidated session
Specifies the time, in seconds, between client requests before the servlet container will invalidate this session.
An interval value of zero or less indicates that the session should never timeout.
An integer specifying the number of seconds
Returns the object bound with the specified name in this session, or null if no object is bound under the name.
