```
public void setMaxInactiveInterval(int interval)
```
    Description copied from interface: javax.servlet.http.HttpSession

    Specified by:
    
    getMaxInactiveInterval in interface HttpSession

```
public java.lang.Object getAttribute(java.lang.String name)
```
    Description copied from interface: javax.servlet.http.HttpSession

    Specified by:
    
    getAttribute in interface HttpSession
    
    Parameters:
    name - a string specifying the name of the object
    
    Returns:
    the object with the specified name
  - getValue
```
@Deprecated
public java.lang.Object getValue(java.lang.String name)
```
    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
  - getAttributeNames
```
public java.util.Enumeration<java.lang.String> getAttributeNames()
```
    Description copied from interface: javax.servlet.http.HttpSession
    
    Returns an Enumeration of String objects containing the names of all the objects bound to this session.
    
    Specified by:
    
    getAttributeNames in interface HttpSession
    
    Returns:
    an Enumeration of String objects specifying the names of all the objects bound to this session
  - getValueNames
```
@Deprecated
public java.lang.String[] getValueNames()
```
    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
  - setAttribute
```
public void setAttribute(java.lang.String name,
                java.lang.Object value)
```
    Description copied from interface: javax.servlet.http.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
  - putValue
```
@Deprecated
public void putValue(java.lang.String name,
                       java.lang.Object value)
```
    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
  - removeAttribute
```
public void removeAttribute(java.lang.String name)
```
    Description copied from interface: javax.servlet.http.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
```
@Deprecated
public void removeValue(java.lang.String name)
```
    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
  - invalidate
```
public void invalidate()
```
    Description copied from interface: javax.servlet.http.HttpSession
    
    Invalidates this session then unbinds any objects bound to it.
    
    Specified by:
    
    invalidate in interface HttpSession
  - isNew
```
public boolean isNew()
```
    Description copied from interface: javax.servlet.http.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
