/** |
|
* A program element annotated {@code @Deprecated} is one that programmers |
|
* are discouraged from using. An element may be deprecated for any of several |
|
* reasons, for example, its usage is likely to lead to errors; it may |
|
* be changed incompatibly or removed in a future version; it has been |
|
* superseded by a newer, usually preferable alternative; or it is obsolete. |
|
* |
|
* <p>Compilers issue warnings when a deprecated program element is used or |
|
* overridden in non-deprecated code. Use of the {@code @Deprecated} |
|
* annotation on a local variable declaration or on a parameter declaration |
|
* or a package declaration has no effect on the warnings issued by a compiler. |
|
* |
|
* <p>When a module is deprecated, the use of that module in {@code |
|
* requires}, but not in {@code exports} or {@code opens} clauses causes |
|
* a warning to be issued. A module being deprecated does <em>not</em> cause |
|
* warnings to be issued for uses of types within the module. |
|
* |
|
* <p>This annotation type has a string-valued element {@code since}. The value |
|
* of this element indicates the version in which the annotated program element |
|
* was first deprecated. |
|
* |
|
* <p>This annotation type has a boolean-valued element {@code forRemoval}. |
|
* A value of {@code true} indicates intent to remove the annotated program |
|
* element in a future version. A value of {@code false} indicates that use of |
|
* the annotated program element is discouraged, but at the time the program |
|
* element was annotated, there was no specific intent to remove it. |
|
* |
|
* @apiNote |
|
* It is strongly recommended that the reason for deprecating a program element |
|
* be explained in the documentation, using the {@code @deprecated} |
|
* javadoc tag. The documentation should also suggest and link to a |
|
* recommended replacement API, if applicable. A replacement API often |
|
* has subtly different semantics, so such issues should be discussed as |
|
* well. |
|
* |
|
* <p>It is recommended that a {@code since} value be provided with all newly |
|
* annotated program elements. Note that {@code since} cannot be mandatory, |
|
* as there are many existing annotations that lack this element value. |
|
* |
|
* <p>There is no defined order among annotation elements. As a matter of |
|
* style, the {@code since} element should be placed first. |
|
* |
|
* <p>The {@code @Deprecated} annotation should always be present if |
|
* the {@code @deprecated} javadoc tag is present, and vice-versa. |
