Class ConcurrentInfo

java.lang.Object

com.sun.management.ConcurrentInfo

All Implemented Interfaces:

PhaseInfo, CompositeDataView

public class ConcurrentInfo
extends Object
implements PhaseInfo, CompositeDataView

A ConcurrentInfo object represents a concurrent phase within a garbage collection. It includes a timestamp specifying the time since the launch of the Java virtual machine process at which the phase started, the wall clock time duration of the phase, plus additional, optional information.

Since:

18

Method Summary

Modifier and Type	Method	Description
static ConcurrentInfo	from(CompositeData cd)
long	getEndTimeNanos()	The approximate end time of this phase in nanoseconds since Java virtual machine launch.
long	getId()	Returns the identifier of this phase, which is the number of phases of this type done by this collector.
String	getPhaseCause()	The reason that for this phase.
long	getPhaseGarbageCollectorThreadCount()	The number of garbage collection threads used during this phase from the pool of garbage collection threads of the associated collector.
String	getPhaseType()	The type of this phase.
long	getStartTimeNanos()	The approximate start time of this phase in nanoseconds since the Java virtual machine was started.
CompositeData	toCompositeData(CompositeType ct)	Return the CompositeData representation of this ConcurrentInfo, including any phase-specific attributes.

Method Details

getPhaseType

public String getPhaseType()

Description copied from interface: PhaseInfo

The type of this phase. Types are unique across the Java virtual machine.

Specified by:

getPhaseType in interface PhaseInfo

Returns:

a String representing the type of this pause.

getId

public long getId()

Description copied from interface: PhaseInfo

Returns the identifier of this phase, which is the number of phases of this type done by this collector.

Specified by:

getId in interface PhaseInfo

Returns:

the identifier of this phase, which is the number of phases of this type done by this collector

getStartTimeNanos

public long getStartTimeNanos()

Description copied from interface: PhaseInfo

The approximate start time of this phase in nanoseconds since the Java virtual machine was started.

Specified by:

getStartTimeNanos in interface PhaseInfo

Returns:

the start time of this phase.

getEndTimeNanos

public long getEndTimeNanos()

Description copied from interface: PhaseInfo

The approximate end time of this phase in nanoseconds since Java virtual machine launch.

Specified by:

getEndTimeNanos in interface PhaseInfo

Returns:

the end time of this phase.

getPhaseGarbageCollectorThreadCount

public long getPhaseGarbageCollectorThreadCount()

Description copied from interface: PhaseInfo

The number of garbage collection threads used during this phase from the pool of garbage collection threads of the associated collector.

Specified by:

getPhaseGarbageCollectorThreadCount in interface PhaseInfo

Returns:

the number of garbage collection threads used during this phase.

getPhaseCause

public String getPhaseCause()

Description copied from interface: PhaseInfo

The reason that for this phase. Reasons are unique across the Java virtual machine.

Specified by:

getPhaseCause in interface PhaseInfo

Returns:

a String representing the reason for this phase.

toCompositeData

public CompositeData toCompositeData(CompositeType ct)

Return the CompositeData representation of this ConcurrentInfo, including any phase-specific attributes. The returned value will have at least all the attributes described in the from method.

Specified by:

toCompositeData in interface CompositeDataView

Parameters:

ct - the CompositeType that the caller expects. This parameter is ignored and can be null.

Returns:

the CompositeData representation.
