gr.uoa.di.madgik.grs.registry.LifecycleManager
public class LifecycleManager
The LifecycleManager
is a utility class that monitors the items registered with the GRSRegistry
and makes sure that they are properly purged when their lifecycle properties dictates their disposal. The property
that is taken into account in this decision is the last activity time of each entry. Whenever its inactivity
time has extended over the timeout set for each one, the item is disposed. The timeout that is taken into account
for IBuffer
s, is IBuffer.getInactivityTimeout()
and IBuffer.getInactivityTimeUnit()
. For
IBufferStore
s, is IBufferStore.getInactivityTimeout()
and IBufferStore.getInactivityTimeUnit()
.
The check is performed with a dynamically defined period. Initially this period is set to
DefaultCheckPeriod
. During each iteration, the minimum of the non to be disposed remaining lifetime
is selected for both IBuffer
and IBufferStore
entries. At every subsequent iteration, this period is recomputed
to avoid unnecessary checks
