public final class Compiler extends Object
The 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.
public static boolean compileClass(Class<?> clazz)
Compiles the specified class.
clazz - A classtrue if the compilation succeeded; false if the compilation failed or no compiler is availableNullPointerException - If clazz is null
public static boolean compileClasses(String string)
Compiles all classes whose name matches the specified string.
string - The name of the classes to compiletrue if the compilation succeeded; false if the compilation failed or no compiler is availableNullPointerException - If string is null
public static Object command(Object any)
Examines the argument type and its fields and perform some documented operation. No specific operations are required.
any - An argumentnull if no compiler is availableNullPointerException - If any is null
