getPreemptionLatency

public javax.realtime.RelativeTime getPreemptionLatency()

Description copied from class: GarbageCollector

Preemption latency is a measure of the maximum time a RealtimeThread may have to wait for the collector to reach a preemption-safe point. Instances of RealtimeThread are allowed to preempt the garbage collector (instances of NoHeapRealtimeThread preempt immediately but instances of RealtimeThread must wait until the collector reaches a preemption-safe point).

Specified by:

getPreemptionLatency in class GarbageCollector

Returns:

The preempting latency of the garbage collection algorithm represented by this if applicable. May return zero, if there is no collector available.
