java.lang.management.CompilationMXBean |
The management interface for the compilation 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 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

Returns the name of the Just-in-time (JIT) compiler.

spent in compilation.

Tests if the Java virtual machine supports the monitoring of
compilation time.

Returns the name of the Just-in-time (JIT) compiler.
Returns the approximate accumlated 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.
UnsupportedOperationException | if the Java virtual machine does not support this operation. |
