/** |
|
29 |
* The {@code Compiler} class is provided to support Java-to-native-code |
|
30 |
* compilers and related services. By design, the {@code Compiler} class does |
|
31 |
* nothing; it serves as a placeholder for a JIT compiler implementation. |
|
32 |
* |
|
33 |
* <p> When the Java Virtual Machine first starts, it determines if the system |
|
34 |
* property {@code java.compiler} exists. (System properties are accessible |
|
35 |
* through {@link System#getProperty(String)} and {@link |
|
36 |
* System#getProperty(String, String)}. If so, it is assumed to be the name of |
|
37 |
* a library (with a platform-dependent exact location and type); {@link |
|
38 |
* System#loadLibrary} is called to load that library. If this loading |
|
39 |
* succeeds, the function named {@code java_lang_Compiler_start()} in that |
|
40 |
* library is called. |
|
41 |
* |
|
42 |
* <p> If no compiler is available, these methods do nothing. |
