public final class Compiler extends Object
Compiler
class is provided to support Java-to-native-code
compilers and related services. By design, the Compiler
class does
nothing; it serves as a placeholder for a JIT compiler implementation.
When the Java Virtual Machine first starts, it determines if the system
property java.compiler
exists. (System properties are accessible
through System.getProperty(String)
and System.getProperty(String, String)
. If so, it is assumed to be the name of
a library (with a platform-dependent exact location and type); System.loadLibrary(java.lang.String)
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.
