ClassLoadingMXBean (Java Platform SE 6)

This documentation differs from the official API. Jadeite adds extra features to the API including: variable font sizes, constructions examples, placeholders for classes and methods, and auto-generated “See Also” links. Additionally it is missing some items found in standard Javadoc documentation, including: generics type information, “Deprecated” tags and comments, “See Also” links, along with other minor differences. Please send any questions or feedback to bam@cs.cmu.edu.

DETAIL: FIELD | CONSTR | METHOD

java.lang.management
interface ClassLoadingMXBean

public interface ClassLoadingMXBean

The management interface for the class loading system of the Java virtual machine.

A Java virtual machine has a single instance of the implementation class of this interface. This instance implementing this interface is an MXBean that can be obtained by calling the {@link ManagementFactory#getClassLoadingMXBean} method or from the {@link ManagementFactory#getPlatformMBeanServer platform MBeanServer} method.

The ObjectName for uniquely identifying the MXBean for the class loading system within an MBeanServer is:

{@link ManagementFactory#CLASS_LOADING_MXBEAN_NAME java.lang:type=ClassLoading}

Method Summary
`int`	`getLoadedClassCount()` Returns the number of classes that are currently loaded in the Java virtual machine.
`long`	`getTotalLoadedClassCount()` Returns the total number of classes that have been loaded since the Java virtual machine has started execution.
`long`	`getUnloadedClassCount()` Returns the total number of classes unloaded since the Java virtual machine has started execution.
`boolean`	`isVerbose()` Tests if the verbose output for the class loading system is enabled.
`void`	`setVerbose(boolean value)` Enables or disables the verbose output for the class loading system.

Method Detail

getLoadedClassCount

public int getLoadedClassCount()

Returns the number of classes that are currently loaded in the Java virtual machine.

Returns:: the number of currently loaded classes.

getTotalLoadedClassCount

public long getTotalLoadedClassCount()

Returns the total number of classes that have been loaded since the Java virtual machine has started execution.

Returns:: the total number of classes loaded.

getUnloadedClassCount

public long getUnloadedClassCount()

Returns the total number of classes unloaded since the Java virtual machine has started execution.

Returns:: the total number of unloaded classes.

isVerbose

public boolean isVerbose()

Tests if the verbose output for the class loading system is enabled.

Returns:: true if the verbose output for the class loading system is enabled; false otherwise.

setVerbose

public void setVerbose(boolean value)

Enables or disables the verbose output for the class loading system. The verbose output information and the output stream to which the verbose information is emitted are implementation dependent. Typically, a Java virtual machine implementation prints a message each time a class file is loaded.

This method can be called by multiple threads concurrently. Each invocation of this method enables or disables the verbose output globally.

Parameters:: value - true to enable the verbose output; false to disable.
