public void touch(long time)
- Access notification. This method takes a time parameter in order
to allow callers to efficiently manage expensive calls to
System.currentTimeMillis()
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[].
getId
public int getId()
- Each object can have an unique id, similar with name but
providing faster access ( array vs. hashtable lookup )
setId
public void setId(int id)
setParent
public void setParent(java.lang.Object o)
- Returns the owner of this stamp ( the object that is
time-stamped ).
For a
getParent
public java.lang.Object getParent()
setCreationTime
public void setCreationTime(long time)
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
setMaxInactiveInterval
public void setMaxInactiveInterval(long interval)
isValid
public boolean isValid()
setValid
public void setValid(boolean isValid)
isNew
public boolean isNew()
setNew
public void setNew(boolean isNew)
getCreationTime
public long getCreationTime()
