Method Detail

getName

java.lang.String getName()

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

Returns:

the name of the JIT compiler.

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:

java.lang.UnsupportedOperationException - if the Java virtual machine does not support this operation.

getTotalOutstandingCompiles

long getTotalOutstandingCompiles()

Provides the total number of enqueued and in-progress compilations at the time of request.

Returns:

a long non-negative number indicating compile count

getTotalPerformedProfileDrivenTier1Compiles

long getTotalPerformedProfileDrivenTier1Compiles()

Provides the total number of performed tier 1 compilations driven by ReadyNow by the time of request

Returns:

a long non-negative number indicating compile count

getTotalPerformedProfileDrivenTier2Compiles

long getTotalPerformedProfileDrivenTier2Compiles()

Provides the total number of performed tier 2 compilations driven by ReadyNow by the time of request

Returns:

a long non-negative number indicating compile count

getTotalPerformedTier1Compiles

long getTotalPerformedTier1Compiles()

Provides the total number of tier 1 compilations performed by the time of request

Returns:

a long non-negative number indicating compile count

getTotalPerformedTier2Compiles

long getTotalPerformedTier2Compiles()

Provides the total number of tier 2 compilations performed by the time of request

Returns:

a long non-negative number indicating compile count

getVersion

java.lang.String getVersion()

Version of the CompilationMXBean application programming interface. The format for the version is majorVersion.minorVersion.microVersion.

Returns:

version of the CompilationMXBean application programming interface.

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.
