Method Detail

getRequestStatistics

public ExecutionStatistics getRequestStatistics()

Description copied from interface: ResourceMethodStatistics

Get execution statistics that contain measurements of times for whole processing from time when request comes into the Jersey application until the response is written to the underlying IO container. The statistics involves only requests that were matched to resource method defined by ResourceMethodStatistics.getResourceMethod().

Specified by:

getRequestStatistics in interface ResourceMethodStatistics

Returns:

Execution statistics of entire request processing for one resource method.

getMethodStatistics

public ExecutionStatistics getMethodStatistics()

Description copied from interface: ResourceMethodStatistics

Get execution statistics that contain measurements of times only for execution of resource method. Durations average time, minimum time and maximum time measure only time of execution of resource method code. It does not involve other request processing phases.

Specified by:

getMethodStatistics in interface ResourceMethodStatistics

Returns:

Execution statistics of one resource method.

getResourceMethod

public ResourceMethod getResourceMethod()

Description copied from interface: ResourceMethodStatistics

Get a resource method for which this ResourceMethodStatistics are calculated.

Specified by:

getResourceMethod in interface ResourceMethodStatistics

Returns:

Resource method.

snapshot

public ResourceMethodStatistics snapshot()

Description copied from interface: ResourceMethodStatistics

Get the immutable and consistent snapshot of the monitoring statistics. Working with snapshots might have negative performance impact as snapshot must be created but ensures consistency of data over time. However, the usage of snapshot is encouraged to avoid working with inconsistent data. Not all statistics must be updated in the same time on mutable version of statistics.

Specified by:

snapshot in interface ResourceMethodStatistics

Returns:

Snapshot of resource method statistics.
