public class MemoryPoolNotificationInfo
extends java.lang.Object

Memory pool notification information.

Field Summary

Fields

Modifier and Type	Field and Description
static java.lang.String	MEMORY_LIVE_SET_SIZE_THRESHOLD_EXCEEDED Notification that the live set size of this memory pool has exceeded the threshold specified by using MemoryPoolMXBean.setLiveSetSizeThreshold(long); This is a threshold notification and requires that a threshold value greater than zero be set using the MemoryPoolMXBean.setLiveSetSizeThreshold(long) method; The check to see whether this threshold has been exceeded is made after each garbage collection has completed.
static java.lang.String	MEMORY_USE_AFTER_COLLECTION_THRESHOLD_EXCEEDED Notification that the memory use by this memory pool has exceeded the threshold specified by using MemoryPoolMXBean.setAfterCollectionUseThreshold(long); This is a threshold notification and requires that a threshold value greater than zero be set using the MemoryPoolMXBean.setAfterCollectionUseThreshold(long) method; The check to see whether this threshold has been exceeded is made after each garbage collection has completed.
static java.lang.String	MEMORY_USE_THRESHOLD_EXCEEDED Notification that the memory use by this memory pool has exceeded the threshold specified by using MemoryPoolMXBean.setUseThreshold(long); This is a threshold notification and requires that a threshold value greater than zero be set using the MemoryPoolMXBean.setUseThreshold(long) method; The check to see whether this threshold has been exceeded is made repeatedly at a time interval that is configurable.

Constructs a MemoryPoolNotificationInfo instance.

Parameters:

poolName - The memory pool name.

notificationReason - The reason for the notification.

count - The number of times the threshold has been crossed

memoryUsage - The memory usage snapshot.

Throws:

java.lang.IllegalArgumentException - if poolName or notificationReason or memoryUsage is null

Method Detail

from

public static MemoryPoolNotificationInfo from(javax.management.openmbean.CompositeData cd)

Constructs a MemoryPoolNotificationInfo object from the CompositeData passed.

Parameters:

cd - The CompositeData object from which to retrieve the MemoryPoolNotificationInfo data.

Returns:

A {code MemoryPoolNotificationInfo} instance or null if cd is null its contents are invalid.

Throws:

java.lang.IllegalArgumentException - if cd does not contain valid MemoryPoolNotification data.

java.lang.NullPointerException - if attributes in the cd are not valid.
