- * The `@Deprecated()` decorators wraps the given method in such a way that it is marked as deprecated.
- *
- * ```typescript
- * provide Foo {
- *
- * @Deprecated("Foo.method: Use Foo.method2 instead")
- * public method() {
- *
- * }
- * ```
- *
- * When called, @Deprecated() will return a function that will emit a `DeprecationWarning` using the `process.on('warning')` event.
- * By default, this warning will be emitted and printed to `stderr` exactly once, the first time it is called. After the warning is emitted, the wrapped method is called.
- *
- * If either the `--no-deprecation` or `--no-warnings` command line flags are used, or if the `process.noDeprecation`
- * property is set to `true` prior to the first deprecation warning, the `@Deprecated()` decorators does nothing.
- *
- * If the `--trace-deprecation` or `--trace-warnings` command line flags are set, or the `process.traceDeprecation`
- * property is set to `true`, a warning and a stack trace are printed to stderr the first time the deprecated function is called.
- *
- * If the `--throw-deprecation` command line flag is set, or the `process.throwDeprecation` property is set to `true`,
- * then an exception will be thrown when the deprecated function is called.
- *
- * The `--throw-deprecation` command line flag and `process.throwDeprecation` property take precedence over `--trace-deprecation`
- * and `process.traceDeprecation`.
