Class java.lang.Compiler

public final class Compiler

extends Object

When the Java Virtual Machine first starts, it determines if the system property java.compiler exists. (System properties are accessible through getProperty and , a method defined by the System class.) If so, it is assumed to be the name of a library (with a platform-dependent exact location and type); the loadLibrary method in class System is called to load that library. If this loading succeeds, the function named java_lang_Compiler_start() in that library is called.

If no compiler is available, these methods do nothing.
