Method Detail

getSamplingManifestURL

public @Nullable java.net.URL getSamplingManifestURL()

shouldTrace

public SamplingResponse shouldTrace(SamplingRequest samplingRequest)

Specified by:

shouldTrace in interface SamplingStrategy

shutdown

public void shutdown()

Description copied from interface: SamplingStrategy

Shutdown additional resources created by advanced sampling strategies.

Specified by:

shutdown in interface SamplingStrategy

getClientID

public static java.lang.String getClientID()

isForcedSamplingSupported

public boolean isForcedSamplingSupported()

Description copied from interface: SamplingStrategy

Returns whether or not this sampling strategy supports 'forced sampling'. Forced sampling allows a segment's initial non-sampled decision to be later overriden to sampled. Supporting this feature requires that all segments, sampled or otherwise, be kept in memory for the duration of their existence. Not supporting this feature saves memory and computational capacity.

Specified by:

isForcedSamplingSupported in interface SamplingStrategy

Returns:

whether or not forced sampling is supported
