extends Object
implements CompilationMXBean
Class Inheritance
All Implemented Interfaces
java.lang.management.CompilationMXBean, java.lang.management.PlatformManagedObject
Imports
java.lang.management.CompilationMXBean, .ManagementFactory, javax.management.ObjectName
Implementation class for the compilation subsystem. Standard and committed hotspot-specific metrics if any. ManagementFactory.getCompilationMXBean() returns an instance of this class.

public String getName()

Implements java.lang.management.CompilationMXBean.getName.

Doc from java.lang.management.CompilationMXBean.getName.

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

getObjectNameback to summary
public ObjectName getObjectName()

Implements java.lang.management.PlatformManagedObject.getObjectName.

Doc from java.lang.management.PlatformManagedObject.getObjectName.

Returns an ObjectName instance representing the object name of this platform managed object.

getTotalCompilationTimeback to summary
public long getTotalCompilationTime()

Implements java.lang.management.CompilationMXBean.getTotalCompilationTime.

Doc from java.lang.management.CompilationMXBean.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.

Doc from java.lang.management.CompilationMXBean.isCompilationTimeMonitoringSupported.

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