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
| Method Summary | ||
| getName() Returns the name of the Just-in-time (JIT) compiler. |
||
long |
getTotalCompilationTime() Returns the approximate accumlated elapsed time (in milliseconds)
spent in compilation. |
|
boolean |
isCompilationTimeMonitoringSupported() Tests if the Java virtual machine supports the monitoring of
compilation time. |
|
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.
