Class TimeStamp

public final class TimeStamp extends Object implements Serializable

Main tool for object expiry. Marks creation and access time of an "expirable" object, and extra properties like "id", "valid", etc. Used for objects that expire - originally Sessions, but also Contexts, Servlets, cache - or any other object that expires.

getId

public int getId()

Each object can have an unique id, similar with name but providing faster access ( array vs. hashtable lookup )

getLastAccessedTime

public long getLastAccessedTime()

getMaxInactiveInterval

public long getMaxInactiveInterval()

Inactive interval in millis - the time is computed in millis, convert to secs in the upper layer

getName

public MessageBytes getName()

Return the "name" of the timestamp. This can be used to associate unique identifier with each timestamped object. The name is a MessageBytes - i.e. a modifiable byte[] or char[].
