Java in a Nutshell, 5th Edition [Electronic resources] نسخه متنی

The static methods of this class provide an
interface to the just-in-time (JIT)
byte-code-to-native code compiler in
use by the Java interpreter. If no JIT compiler is in use by the VM,
these methods do nothing. compileClass( ) asks the
JIT compiler to compile the specified class. compileClasses(
) asks the JIT compiler to compile all classes that match
the specified name. These methods return true if
the compilation was successful, or false if it
failed or if there is no JIT compiler on the system. enable(
) and disable( ) turn just-in-time
compilation on and off. command( ) asks the JIT
compiler to perform some compiler-specific operation; this is a hook
for vendor extensions. No standard operations have been defined.
