MemoryUsageCompositeData

extends LazyCompositeData

java.lang.Object
↳	sun.management.LazyCompositeData
	↳	sun.management.MemoryUsageCompositeData

Class Overview

A CompositeData for MemoryUsage for the local management support. This class avoids the performance penalty paid to the construction of a CompositeData use in the local case.

Inherited Methods

From class sun.management.LazyCompositeData

boolean	containsKey(String key) Returns `true` if and only if this `CompositeData` instance contains an item whose name is `key`.
boolean	containsValue(Object value) Returns `true` if and only if this `CompositeData` instance contains an item whose value is `value`.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
Object	get(String key) Returns the value of the item whose name is `key`.
Object[]	getAll(String[] keys) Returns an array of the values of the items whose names are specified by `keys`, in the same order as `keys`.
abstract CompositeData	getCompositeData() Returns the CompositeData representing this object.
CompositeType	getCompositeType() Returns the composite type of this composite data instance.
int	hashCode() Returns a hash code value for the object.
static boolean	isTypeMatched(TabularType type1, TabularType type2)
static boolean	isTypeMatched(CompositeType type1, CompositeType type2) Compares two CompositeTypes and returns true if all items in type1 exist in type2 and their item types are the same.
String	toString() Returns a string representation of the object.
Collection	values() Returns an unmodifiable Collection view of the item values contained in this `CompositeData` instance.
Object	writeReplace() Designate to a CompositeData object when writing to an output stream during serialization so that the receiver only requires JMX 1.2 classes but not any implementation specific class.

From class java.lang.Object

Object	clone() Creates and returns a copy of this object.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
void	finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
final Class<?>	getClass() Returns the runtime class of this `Object`.
int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait() Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
final void	wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
final void	wait(long timeout) Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

From interface javax.management.openmbean.CompositeData

abstract boolean	containsKey(String key) Returns `true` if and only if this `CompositeData` instance contains an item whose name is `key`.
abstract boolean	containsValue(Object value) Returns `true` if and only if this `CompositeData` instance contains an item whose value is `value`.
abstract boolean	equals(Object obj) Compares the specified `obj` parameter with this `CompositeData` instance for equality.
abstract Object	get(String key) Returns the value of the item whose name is `key`.
abstract Object[]	getAll(String[] keys) Returns an array of the values of the items whose names are specified by `keys`, in the same order as `keys`.
abstract CompositeType	getCompositeType() Returns the composite type of this composite data instance.
abstract int	hashCode() Returns the hash code value for this `CompositeData` instance.
abstract String	toString() Returns a string representation of this `CompositeData` instance.
abstract Collection<?>	values() Returns an unmodifiable Collection view of the item values contained in this `CompositeData` instance.

Public Methods

public static long getCommitted (CompositeData cd)

public static long getInit (CompositeData cd)

public static long getMax (CompositeData cd)

public MemoryUsage getMemoryUsage ()

public static long getUsed (CompositeData cd)

public static CompositeData toCompositeData (MemoryUsage u)

public static void validateCompositeData (CompositeData cd)

Validate if the input CompositeData has the expected CompositeType (i.e. contain all attributes with expected names and types).

Protected Methods

protected CompositeData getCompositeData ()

Returns the CompositeData representing this object. The returned CompositeData object must be an instance of javax.management.openmbean.CompositeDataSupport class so that no implementation specific class is required for unmarshalling besides JMX 1.2 classes.
