getValueNames in interface HttpSession

Returns:

an array of String objects specifying the names of all the objects bound to this session

Throws:

java.lang.IllegalStateException - if this method is called on an invalidated session

access

protected void access(long time)

complete

protected void complete()

timeout

protected void timeout()
                throws java.lang.IllegalStateException

Throws:

java.lang.IllegalStateException

invalidate

public void invalidate()
                throws java.lang.IllegalStateException

Description copied from interface: HttpSession

Invalidates this session then unbinds any objects bound to it.

Specified by:

invalidate in interface HttpSession

Throws:

Throws:

java.lang.IllegalStateException

isIdChanged

public boolean isIdChanged()

isNew

public boolean isNew()
              throws java.lang.IllegalStateException

Description copied from interface: HttpSession

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.

Specified by:

isNew in interface HttpSession

Returns:

true if the server has created a session, but the client has not yet joined

Throws:

java.lang.IllegalStateException - if this method is called on an already invalidated session

putValue

public void putValue(java.lang.String name,
                     java.lang.Object value)
              throws java.lang.IllegalStateException

Deprecated. As of Version 2.2, this method is replaced by setAttribute(java.lang.String, java.lang.Object)

Specified by:

putValue in interface HttpSession

Parameters:

name - the name to which the object is bound; cannot be null

value - the object to be bound; cannot be null

Throws:

java.lang.IllegalStateException - if this method is called on an invalidated session

removeAttribute

public void removeAttribute(java.lang.String name)

Description copied from interface: HttpSession

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.

Specified by:

removeAttribute in interface HttpSession

Parameters:

name - the name of the object to remove from this session

removeValue

public void removeValue(java.lang.String name)
                 throws java.lang.IllegalStateException

Deprecated. As of Version 2.2, this method is replaced by removeAttribute(java.lang.String)

Specified by:

removeValue in interface HttpSession

Parameters:

name - the name of the object to remove from this session

Throws:

java.lang.IllegalStateException - if this method is called on an invalidated session

setAttribute

public void setAttribute(java.lang.String name,
                         java.lang.Object value)

Description copied from interface: HttpSession

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().

Specified by:

setAttribute in interface HttpSession

Parameters:

name - the name to which the object is bound; cannot be null

value - the object to be bound

setIdChanged

public void setIdChanged(boolean changed)

setMaxInactiveInterval

public void setMaxInactiveInterval(int secs)

Description copied from interface: HttpSession

Specifies the time, in seconds, between client requests before the servlet container will invalidate this session. A negative time indicates the session should never timeout.

Specified by:

setMaxInactiveInterval in interface HttpSession

Parameters:

secs - An integer specifying the number of seconds

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

bindValue

protected void bindValue(java.lang.String name,
                         java.lang.Object value)
