|
248 |
// * A helper program to generate the VarHandleGuards class with a set of |
|
249 |
// * static guard methods each of which corresponds to a particular shape and |
|
250 |
// * performs a type check of the symbolic type descriptor with the VarHandle |
|
251 |
// * type descriptor before linking/invoking to the underlying operation as |
|
252 |
// * characterized by the operation member name on the VarForm of the |
|
253 |
// * VarHandle. |
|
254 |
// * <p> |
|
255 |
// * The generated class essentially encapsulates pre-compiled LambdaForms, |
|
256 |
// * one for each method, for the most set of common method signatures. |
|
257 |
// * This reduces static initialization costs, footprint costs, and circular |
|
258 |
// * dependencies that may arise if a class is generated per LambdaForm. |
|
259 |
// * <p> |
|
260 |
// * A maximum of L*T*S methods will be generated where L is the number of |
|
261 |
// * access modes kinds (or unique operation signatures) and T is the number |
|
262 |
// * of variable types and S is the number of shapes (such as instance field, |
|
263 |
// * static field, or array access). |
|
264 |
// * If there are 4 unique operation signatures, 5 basic types (Object, int, |
|
265 |
// * long, float, double), and 3 shapes then a maximum of 60 methods will be |
|
266 |
// * generated. However, the number is likely to be less since there |
|
267 |
// * be duplicate signatures. |
|
268 |
// * <p> |
|
269 |
// * Each method is annotated with @LambdaForm.Compiled to inform the runtime |
|
270 |
// * that such methods should be treated as if a method of a class that is the |
|
271 |
// * result of compiling a LambdaForm. Annotation of such methods is |
|
272 |
// * important for correct evaluation of certain assertions and method return |
|
273 |
// * type profiling in HotSpot. |
