25.16 java.lang.Compiler (JDK 1.0)

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.

public final class Compiler extends Object {
    // No Constructor
    // Class Methods
            public static native Object command(Object any);
            public static native boolean compileClass(Class clazz);
            public static native boolean compileClasses(String string);
            public static native void disable();
            public static native void enable();
