  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:

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

### isIdChanged

    public boolean isIdChanged()

### 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

### 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 `HttpSessionAttributeListener`s 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 `HttpSessionAttributeListener`s 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 String toString()

  Overrides:
    `toString` in class `Object`

### access

    protected void access(long time)

### bindValue

    protected void bindValue(String name,
                             Object value)

  If value implements HttpSessionBindingListener, call valueBound()

### getClusterId

    protected String getClusterId()

### isValid

    protected boolean isValid()

### newAttributeMap

    protected abstract Map newAttributeMap()

### cookieSet

    protected void cookieSet()

### unbindValue

    protected void unbindValue(String name,
                               Object value)

  If value implements HttpSessionBindingListener, call valueUnbound()
