Method Detail

statisticToMap

public static Map<String,Object> statisticToMap(Statistic statistic)

Convert the Statistic into a Map containing all the name/value pairs obtained by finding method names that match a getter pattern getXXX(). Any Statistic can thus be converted into a Map which preserves all its members.

Parameters:

statistic - any Statistic or subclass

getStatisticType

public static String getStatisticType(Statistic statistic)

Get the type name for a Statistic.

statisticToCompositeType

public static CompositeType statisticToCompositeType(Statistic statistic)
                                              throws OpenDataException

Get the JMX OpenMBean CompositeType corresponding to the Statistic.

Throws:

OpenDataException

statisticToCompositeData

public static CompositeDataSupport statisticToCompositeData(Statistic statistic)
                                                     throws OpenDataException

Convert a Statistic into a JMX CompositeDataSupport.

Parameters:

statistic - any Statistic or subclass

Throws:

OpenDataException

getStatsType

public static String getStatsType(Stats stats)

Get the type for use in a CompositeType type.

statsToCompositeData

public static CompositeDataSupport statsToCompositeData(Stats stats)
                                                 throws OpenDataException

Convert a Stats object into a CompositeDataSupport, which is a standard type in JMX which can be serialized.

The CompositeData entries will keyed by the name of the Statistic. The value of each Statistic will also be a CompositeData, keyed by the value names found in that statistic.

For example, the JVMStats object would be converted into a CompositeData with the entries:

• HeapSize
• Description
• LastSampleTime
• Name
• StartTime
• Unit
• LowerBound
• UpperBound
• HighWaterMark
• LowWaterMark
• Current
• UpTime
• Description
• LastSampleTime
• Name
• StartTime
• Unit
• Count

Parameters:

stats - any JSR 77 Stats object

Throws:

OpenDataException

statsToMap

public static Map<String,Statistic> statsToMap(Stats stats)

Turn a Stats object into a Map containing all its Statistics, keyed by Statistic.getName() and value of the Statistic.

statisticsToMap

public static Map<String,Statistic> statisticsToMap(Statistic[] statistics)

Convert a Statistic[] into a Map keyed by the name of the Statistic, with value being the Statistic.

Returns:

Map keyed by name of the Statistic

getStatisticGetterMethodsUsingNames

public static Method[] getStatisticGetterMethodsUsingNames(Stats stats)
                                                    throws NoSuchMethodException

Throws:

NoSuchMethodException

getStatisticGetterMethodsUsingIntrospection

public static Method[] getStatisticGetterMethodsUsingIntrospection(Stats stats)
