Method Detail

getAttribute

public Object getAttribute(String name)

Description copied from interface: HttpSession

Returns the object bound with the specified name in this session, or null if no object is bound under the name.

name - a string specifying the name of the object

Returns:

the object with the specified name

getAttributeNames in interface HttpSession

Returns:

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

getCreationTime

public long getCreationTime()
                     throws IllegalStateException

Description copied from interface: HttpSession

Returns the time when this session was created, measured in milliseconds since midnight January 1, 1970 GMT.

Specified by:

getCreationTime in interface HttpSession

Returns:

a long specifying when this session was created, expressed in milliseconds since 1/1/1970 GMT

Throws:

IllegalStateException - if this method is called on an invalidated session

getId

public String getId()
             throws IllegalStateException

Description copied from interface: HttpSession

Returns a string containing the unique identifier assigned to this session. The identifier is assigned by the servlet container and is implementation dependent.

Specified by:

getId in interface HttpSession

Returns:

a string specifying the identifier assigned to this session

Throws:

IllegalStateException - if this method is called on an invalidated session

getLastAccessedTime

public long getLastAccessedTime()
                         throws IllegalStateException

Description copied from interface: HttpSession

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.

Specified by:

getLastAccessedTime in interface HttpSession

Returns:

a long representing the last time the client sent a request associated with this session, expressed in milliseconds since 1/1/1970 GMT

Throws:

IllegalStateException - if this method is called on an invalidated session

getMaxInactiveInterval

public int getMaxInactiveInterval()

Description copied from interface: HttpSession

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 negative time indicates the session should never timeout.

Specified by:

getMaxInactiveInterval in interface HttpSession

Returns:

an integer specifying the number of seconds this session remains open between client requests

See Also:

HttpSession.setMaxInactiveInterval(int)

getServletContext

public ServletContext getServletContext()

Description copied from interface: HttpSession

Returns the ServletContext to which this session belongs.

Specified by:

getServletContext in interface HttpSession

Returns:

The ServletContext object for the web application

getSessionContext

public HttpSessionContext getSessionContext()
                                     throws IllegalStateException

Deprecated.

Specified by:

getSessionContext in interface HttpSession

Throws:

IllegalStateException

getValue

public Object getValue(String name)
                throws IllegalStateException

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

Specified by:

getValue in interface HttpSession

Parameters:

name - a string specifying the name of the object

Returns:

the object with the specified name

Throws:

IllegalStateException - if this method is called on an invalidated session

getValueNames

public String[] getValueNames()
                       throws IllegalStateException

Deprecated. As of Version 2.2, this method is replaced by getAttributeNames()

Specified by:

getValueNames in interface HttpSession

Returns:

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

Throws:

IllegalStateException - if this method is called on an invalidated session

invalidate

public void invalidate()
                throws IllegalStateException

Description copied from interface: HttpSession

Invalidates this session then unbinds any objects bound to it.

Specified by:

invalidate in interface HttpSession

Throws:

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

isNew

public boolean isNew()
              throws 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:

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

newAttributeMap

protected abstract Map newAttributeMap()

putValue

public void putValue(String name,
                     Object value)
              throws 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:

IllegalStateException - if this method is called on an invalidated session

removeAttribute

public void removeAttribute(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(String name)
                 throws 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:

IllegalStateException - if this method is called on an invalidated session

setAttribute

public void setAttribute(String name,
                         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

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 String toString()
