- All Superinterfaces:
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.- Since:
- 1.5

Method Details
-
getName
String getName()Returns the name of the Just-in-time (JIT) compiler.- Returns:
- the name of the JIT compiler.
-
isCompilationTimeMonitoringSupported
boolean isCompilationTimeMonitoringSupported()Tests if the Java virtual machine supports the monitoring of compilation time.- Returns:
true
if the monitoring of compilation time is supported;false
otherwise.
-
getTotalCompilationTime
long getTotalCompilationTime()Returns the approximate accumulated elapsed time (in milliseconds) spent in compilation. If multiple threads are used for compilation, this value is summation of the approximate time that each thread spent in compilation.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.
- Returns:
- Compilation time in milliseconds
- Throws:
UnsupportedOperationException
- if the Java virtual machine does not support this operation.
