Method Detail

setId

public void setId(java.lang.String id)

getId

public java.lang.String getId()

Description copied from interface: Session

Returns a string containing the unique identifier assigned to this session.

Specified by:

getId in interface Session

setCreatedTime

public void setCreatedTime(long createdTime)

getCreatedTime

public long getCreatedTime()

Description copied from interface: Session

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

Specified by:

getCreatedTime in interface Session

setLastAccessedTime

public void setLastAccessedTime(long lastAccessedTime)

getLastAccessedTime

public long getLastAccessedTime()

Description copied from interface: 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.

Specified by:

getLastAccessedTime in interface Session

setMaxInactiveInterval

public void setMaxInactiveInterval(int interval)

Description copied from interface: Session

Specifies the time, in seconds, between client requests before the server will invalidate this session.

An interval value of zero or less indicates that the session should never timeout.

Specified by:

setMaxInactiveInterval in interface Session

Parameters:

interval - an integer specifying the number of seconds.

getMaxInactiveInterval

public int getMaxInactiveInterval()

Description copied from interface: Session

Returns the maximum time interval, in seconds, that the server will keep this session open between client accesses. After this interval, the server will invalidate the session. The maximum time interval can be set with the Session.setMaxInactiveInterval(int) method.

A return value of zero or less indicates that the session will never timeout.

Specified by:

getMaxInactiveInterval in interface Session

getAttribute

public java.lang.Object getAttribute(java.lang.String name)

Description copied from interface: Session

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

Specified by:

getAttribute in interface Session

Parameters:

name - a string specifying the name of the object.

getAttributeNames

public java.util.Enumeration<java.lang.String> getAttributeNames()

Description copied from interface: Session

Returns an Enumeration of String objects containing the names of all the objects bound to this session.

Specified by:

getAttributeNames in interface Session

setAttribute

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

Description copied from interface: 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.

If the value passed in is null, this has the same effect as calling Session.removeAttribute(String).

Specified by:

setAttribute in interface Session

Parameters:

name - the name to which the object is bound, cannot be null.

value - the object to be bound.

removeAttribute

public void removeAttribute(java.lang.String name)

Description copied from interface: 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.

Specified by:

Parameters:

public void setNew(boolean aNew)

isNew

public boolean isNew()

Description copied from interface: Session

Returns true if the client does not yet know about the session or if the client chooses not to join the session. E.g. 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 Session

Returns:

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

setValid

public void setValid(boolean valid)

isValid

public boolean isValid()

Specified by:
