- * Returns an out-of-bounds exception formatter from an given exception
- * factory. The exception formatter is a function that formats an
- * out-of-bounds message from its arguments and applies that message to the
- * given exception factory to produce and relay an exception.
- *
- * <p>The exception formatter accepts two arguments: a {@code String}
- * describing the out-of-bounds range check that failed, referred to as the
- * <em>check kind</em>; and a {@code List<Integer>} containing the
- * out-of-bound integer values that failed the check. The list of
- * out-of-bound values is not modified.
- *
- * <p>Three check kinds are supported {@code checkIndex},
- * {@code checkFromToIndex} and {@code checkFromIndexSize} corresponding
- * respectively to the specified application of an exception formatter as an
- * argument to the out-of-bounds range check methods
- * {@link #checkIndex(int, int, BiFunction) checkIndex},
- * {@link #checkFromToIndex(int, int, int, BiFunction) checkFromToIndex}, and
- * {@link #checkFromIndexSize(int, int, int, BiFunction) checkFromIndexSize}.
- * Thus a supported check kind corresponds to a method name and the
- * out-of-bound integer values correspond to method argument values, in
- * order, preceding the exception formatter argument (similar in many
- * respects to the form of arguments required for a reflective invocation of
- * such a range check method).
- *
- * <p>Formatter arguments conforming to such supported check kinds will
- * produce specific exception messages describing failed out-of-bounds
- * checks. Otherwise, more generic exception messages will be produced in
- * any of the following cases: the check kind is supported but fewer
- * or more out-of-bounds values are supplied, the check kind is not
- * supported, the check kind is {@code null}, or the list of out-of-bound
- * values is {@code null}.
- *
- * @apiNote
- * This method produces an out-of-bounds exception formatter that can be
- * passed as an argument to any of the supported out-of-bounds range check
- * methods declared by {@code Objects}. For example, a formatter producing
- * an {@code ArrayIndexOutOfBoundsException} may be produced and stored on a
- * {@code static final} field as follows:
- * <pre>{@code
- * static final
- * BiFunction<String, List<Integer>, ArrayIndexOutOfBoundsException> AIOOBEF =
- * outOfBoundsExceptionFormatter(ArrayIndexOutOfBoundsException::new);
- * }</pre>
- * The formatter instance {@code AIOOBEF} may be passed as an argument to an
- * out-of-bounds range check method, such as checking if an {@code index}
- * is within the bounds of a {@code limit}:
- * <pre>{@code
- * checkIndex(index, limit, AIOOBEF);
- * }</pre>
- * If the bounds check fails then the range check method will throw an
- * {@code ArrayIndexOutOfBoundsException} with an appropriate exception
- * message that is a produced from {@code AIOOBEF} as follows:
- * <pre>{@code
- * AIOOBEF.apply("checkIndex", List.of(index, limit));
- * }</pre>
- *
- * @param f the exception factory, that produces an exception from a message
- * where the message is produced and formatted by the returned
- * exception formatter. If this factory is stateless and side-effect
- * free then so is the returned formatter.
- * Exceptions thrown by the factory are relayed to the caller
- * of the returned formatter.

+ * Returns an out-of-bounds exception formatter from an given exception
+ * factory. The exception formatter is a function that formats an
+ * out-of-bounds message from its arguments and applies that message to the
+ * given exception factory to produce and relay an exception.
+ *
+ * <p>The exception formatter accepts two arguments: a {@code String}
+ * describing the out-of-bounds range check that failed, referred to as the
+ * <em>check kind</em>; and a {@code List<Integer>} containing the
+ * out-of-bound integer values that failed the check. The list of
+ * out-of-bound values is not modified.
+ *
+ * <p>Three check kinds are supported {@code checkIndex},
+ * {@code checkFromToIndex} and {@code checkFromIndexSize} corresponding
+ * respectively to the specified application of an exception formatter as an
+ * argument to the out-of-bounds range check methods
+ * {@link #checkIndex(int, int, BiFunction) checkIndex},
+ * {@link #checkFromToIndex(int, int, int, BiFunction) checkFromToIndex}, and
+ * {@link #checkFromIndexSize(int, int, int, BiFunction) checkFromIndexSize}.
+ * Thus a supported check kind corresponds to a method name and the
+ * out-of-bound integer values correspond to method argument values, in
+ * order, preceding the exception formatter argument (similar in many
+ * respects to the form of arguments required for a reflective invocation of
+ * such a range check method).
+ *
+ * <p>Formatter arguments conforming to such supported check kinds will
+ * produce specific exception messages describing failed out-of-bounds
+ * checks. Otherwise, more generic exception messages will be produced in
+ * any of the following cases: the check kind is supported but fewer
+ * or more out-of-bounds values are supplied, the check kind is not
+ * supported, the check kind is {@code null}, or the list of out-of-bound
+ * values is {@code null}.
+ *
+ * @apiNote
+ * This method produces an out-of-bounds exception formatter that can be
+ * passed as an argument to any of the supported out-of-bounds range check
+ * methods declared by {@code Objects}. For example, a formatter producing
+ * an {@code ArrayIndexOutOfBoundsException} may be produced and stored on a
+ * {@code static final} field as follows:
+ * <pre>{@code
+ * static final
+ * BiFunction<String, List<Integer>, ArrayIndexOutOfBoundsException> AIOOBEF =
+ * outOfBoundsExceptionFormatter(ArrayIndexOutOfBoundsException::new);
+ * }</pre>
+ * The formatter instance {@code AIOOBEF} may be passed as an argument to an
+ * out-of-bounds range check method, such as checking if an {@code index}
+ * is within the bounds of a {@code limit}:
+ * <pre>{@code
+ * checkIndex(index, limit, AIOOBEF);
+ * }</pre>
+ * If the bounds check fails then the range check method will throw an
+ * {@code ArrayIndexOutOfBoundsException} with an appropriate exception
+ * message that is a produced from {@code AIOOBEF} as follows:
+ * <pre>{@code
+ * AIOOBEF.apply("checkIndex", List.of(index, limit));
+ * }</pre>
+ *
+ * @param f the exception factory, that produces an exception from a message
+ * where the message is produced and formatted by the returned
+ * exception formatter. If this factory is stateless and side-effect
+ * free then so is the returned formatter.
+ * Exceptions thrown by the factory are relayed to the caller
