Method Detail

touch

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()

getThisAccessedTime

public long getThisAccessedTime()

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()

recycle

public void recycle()
