1.0

Method Detail

getStartTimestamp

Date getStartTimestamp(SessionKey key)
Returns the time the associated Session started (was created).

Parameters:
key - the session key to use to look up the target session.
Returns:
the time the specified Session started (was created).
See Also:
Session.getStartTimestamp()

getLastAccessTime

Date getLastAccessTime(SessionKey key)
Returns the time the associated Session last interacted with the system.

Parameters:
key - the session key to use to look up the target session.
Returns:
time the session last accessed the system
See Also:
Session.getLastAccessTime(), Session.touch()

isValid

boolean isValid(SessionKey key)
Returns true if the associated session is valid (it exists and is not stopped nor expired), false otherwise.

Parameters:
key - the session key to use to look up the target session.
Returns:
true if the session is valid (exists and is not stopped or expired), false otherwise.

checkValid

void checkValid(SessionKey key)
                throws InvalidSessionException
Returns quietly if the associated session is valid (it exists and is not stopped or expired) or throws an InvalidSessionException indicating that the session id is invalid. This might be preferred to be used instead of isValid(org.apache.shiro.session.mgt.SessionKey) since any exception thrown will definitively explain the reason for invalidation.

Parameters:
key - the session key to use to look up the target session.
Throws:
InvalidSessionException - if the session id is invalid (it does not exist or it is stopped or expired).

getTimeout

long getTimeout(SessionKey key)
                throws InvalidSessionException
Returns the time in milliseconds that the associated session may remain idle before expiring.

Parameters:
key - the session key to use to look up the target session.
Returns:
the time in milliseconds that the associated session may remain idle before expiring.
Throws:
InvalidSessionException - if the session has been stopped or expired prior to calling this method.

setTimeout

void setTimeout(SessionKey key,
                long maxIdleTimeInMillis)
                throws InvalidSessionException
Sets the time in milliseconds that the associated session may remain idle before expiring.

Parameters:
key - the session key to use to look up the target session.
maxIdleTimeInMillis - the time in milliseconds that the associated session may remain idle before expiring.
Throws:
InvalidSessionException - if the session has been stopped or expired prior to calling this method.

touch

void touch(SessionKey key)
           throws InvalidSessionException
Updates the last accessed time of the session identified by sessionId. This can be used to explicitly ensure that a session does not time out.

Parameters:
key - the session key to use to look up the target session.
Throws:
InvalidSessionException - if the session has been stopped or expired prior to calling this method.
See Also:
Session.touch()

getHost

String getHost(SessionKey key)
Returns the host name or IP string of the host where the session was started, if known. If no host name or IP was specified when starting the session, this method returns null

Parameters:
key - the session key to use to look up the target session.
Returns:
the host name or ip address of the host where the session originated, if known. If unknown, this method returns null.

stop

void stop(SessionKey key)
          throws InvalidSessionException
Explicitly stops the associated session, thereby releasing all of its resources.

Parameters:
key - the session key to use to look up the target session.
Throws:
InvalidSessionException - if the session has stopped or expired prior to calling this method.
See Also:
Session.stop()

getAttributeKeys

Collection<Object> getAttributeKeys(SessionKey sessionKey)
Returns all attribute keys maintained by the target session or an empty collection if there are no attributes.

Parameters:
sessionKey - the session key to use to look up the target session.
Returns:
all attribute keys maintained by the target session or an empty collection if there are no attributes.
Throws:
InvalidSessionException - if the associated session has stopped or expired prior to calling this method.
See Also:
Session.getAttributeKeys()

getAttribute

Object getAttribute(SessionKey sessionKey,
                    Object attributeKey)
                    throws InvalidSessionException
Returns the object bound to the associated session identified by the specified attribute key. If there is no object bound under the attribute key for the given session, null is returned.

Parameters:
sessionKey - session key to use to look up the target session.
attributeKey - the unique name of the object bound to the associated session
Returns:
the object bound under the attributeKey or null if there is no object bound.
Throws:
InvalidSessionException - if the specified session has stopped or expired prior to calling this method.
See Also:
Session.getAttribute(Object key)

setAttribute

void setAttribute(SessionKey sessionKey,
                  Object attributeKey,
                  Object value)
                  throws InvalidSessionException
Binds the specified value to the associated session uniquely identified by the attributeKey. If there is already a session attribute bound under the attributeKey, that existing object will be replaced by the new value.

If the value parameter is null, it has the same effect as if the removeAttribute(SessionKey sessionKey, Object attributeKey) method was called.

Parameters:
sessionKey - the session key to use to look up the target session.
attributeKey - the key under which the value object will be bound in this session
value - the object to bind in this session.
Throws:
InvalidSessionException - if the specified session has stopped or expired prior to calling this method.
See Also:
Session.setAttribute(Object key, Object value)

removeAttribute

Object removeAttribute(SessionKey sessionKey,
                       Object attributeKey)
                       throws InvalidSessionException
Removes (unbinds) the object bound to associated Session under the given attributeKey.

Parameters:
sessionKey - session key to use to look up the target session.
attributeKey - the key uniquely identifying the object to remove
Returns:
the object removed or null if there was no object bound under the specified attributeKey.
Throws:
InvalidSessionException - if the specified session has stopped or expired prior to calling this method.
See Also:
Session.removeAttribute(Object key)
