- All Superinterfaces:
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
that can be obtained by calling
ManagementFactory.getCompilationMXBean() method or
platform MBeanServer method.
ObjectName for uniquely identifying the MXBean for
the compilation system within an MBeanServer is:
Modifier and Type Method Description
()Returns the name of the Just-in-time (JIT) compiler.
()Returns the approximate accumulated elapsed time (in milliseconds) spent in compilation.
()Tests if the Java virtual machine supports the monitoring of compilation time.
getNameString getName()Returns the name of the Just-in-time (JIT) compiler.
- the name of the JIT compiler.
isCompilationTimeMonitoringSupportedboolean isCompilationTimeMonitoringSupported()Tests if the Java virtual machine supports the monitoring of compilation time.
trueif the monitoring of compilation time is supported;
getTotalCompilationTimelong 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.
- Compilation time in milliseconds
UnsupportedOperationException- if the Java virtual machine does not support this operation.
