Class MonitoringStatisticsImpl

java.lang.Object

org.glassfish.jersey.server.internal.monitoring.MonitoringStatisticsImpl

All Implemented Interfaces:

MonitoringStatistics

final class MonitoringStatisticsImpl
extends java.lang.Object
implements MonitoringStatistics

Monitoring statistics implementation.

This object is loosely immutable (i.e., getResourceClassStatistics() and getUriStatistics() gets updated on access). As a result, it is unnecessary to call snapshot().

Method Detail

getRequestStatistics

public ExecutionStatistics getRequestStatistics()

Description copied from interface: MonitoringStatistics

Get the global application statistics of request execution. The statistics are not bound any specific resource or resource method and contains information about all requests that application handles.

Specified by:

getRequestStatistics in interface MonitoringStatistics

Returns:

Application request execution statistics.

getResponseStatistics

public ResponseStatistics getResponseStatistics()

Description copied from interface: MonitoringStatistics

Get global application response statistics. The statistics are not bound any specific resource or resource method and contains information about all responses that application creates.

Specified by:

getResponseStatistics in interface MonitoringStatistics

Returns:

Application response statistics.

getUriStatistics

public java.util.Map<java.lang.String,ResourceStatistics> getUriStatistics()

Refreshed (re-built) on every access. (uses Maps.transformValues(Map, Function))

Specified by:

getUriStatistics in interface MonitoringStatistics

Returns:

resource statistics

getResourceClassStatistics

public java.util.Map<java.lang.Class<?>,ResourceStatistics> getResourceClassStatistics()

Refreshed (re-built) on every access. (uses Maps.transformValues(Map, Function))

Specified by:

getResourceClassStatistics in interface MonitoringStatistics

Returns:

resource statistics

getExceptionMapperStatistics

public ExceptionMapperStatistics getExceptionMapperStatistics()

Description copied from interface: MonitoringStatistics

Get statistics about registered exception mappers.

Specified by:

getExceptionMapperStatistics in interface MonitoringStatistics

Returns:

Exception mapper statistics.

snapshot

public MonitoringStatistics snapshot()

Description copied from interface: MonitoringStatistics

Get the immutable 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 MonitoringStatistics

Returns:

Snapshot of monitoring statistics.
