| * Indicates that an API should never be inlined. |
| * |
| * <p> |
| * NeverInline can be used to annotate methods that should not be inlined into other methods. |
| * Methods that are not called frequently, are never speed-critical, or are only used for |
| * debugging do not necessarily need to run quickly. Applying this annotation to prevent these |
| * methods from being inlined will return some size improvements in .odex files. |
| * </p> |
| * |
| * <p> |
| * The <code>fillInStackTrace</code> method in java.lang.Throwable can be used as a concrete |
| * example. This is a method that fills in the execution stack trace and it is not used for |
| * performance. Annotating this method with NeverInline can be seen to significantly reduce |
| * the size of services.odex. |
