PlatformManagedObject
public interface CompilationMXBean extends PlatformManagedObject
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 ManagementFactory.getCompilationMXBean()
method or
from the platform MBeanServer
method.
The ObjectName
for uniquely identifying the MXBean for
the compilation system within an MBeanServer is:
java.lang:type=Compilation
It can be obtained by calling the
PlatformManagedObject.getObjectName()
method.ManagementFactory.getPlatformMXBeans(Class)
,

Ways to Access MXBeansModifier and Type | Method | Description |
---|---|---|
String |
getName() |
Returns the name of the Just-in-time (JIT) compiler.
|
long |
getTotalCompilationTime() |
Returns the approximate accumulated elapsed time (in milliseconds)
spent in compilation.
|
boolean |
isCompilationTimeMonitoringSupported() |
Tests if the Java virtual machine supports the monitoring of
compilation time.

String getName()
boolean isCompilationTimeMonitoringSupported()
true
if the monitoring of compilation time is
supported; false
otherwise.long getTotalCompilationTime()
This method is optionally supported by the platform.
A Java virtual machine implementation may not support the compilation
time monitoring. The isCompilationTimeMonitoringSupported()
method can be used to determine if the Java virtual machine
supports this operation.
This value does not indicate the level of performance of the Java virtual machine and is not intended for performance comparisons of different virtual machine implementations. The implementations may have different definitions and different measurements of the compilation time.
UnsupportedOperationException
- if the Java
virtual machine does not support
this operation. Submit a bug or feature
