• CheckedExceptionHandler

  protected CheckedExceptionHandler()

  Initializes new CheckedExceptionHandler.

Method Detail

• handle

  public abstract RuntimeException handle​(Exception exception)

  Converts checked exception into an unchecked one. This method must be defined in a derived class. Several implementations are provided by methods on Exceptions class. All other methods of the CheckedExceptionHandler call this method, but it can be also called directly.

  This method represents reusable catch block that handles all checked exceptions in the same way. When invoked, it must somehow convert the checked exception into an unchecked one, usually by wrapping it. Caller is then expected to throw the returned exception. There can be special cases like Exceptions.sneak(), which don't return at all.

  Callers should not pass in RuntimeException or other unchecked exceptions. This method might erroneously wrap such exceptions as if they are checked exceptions. Methods of this class never pass unchecked exceptions to this method.

  Parameters:

  exception - checked exception to convert

  Returns:

  converted unchecked exception

  Throws:

  NullPointerException - if exception is null

• runnable

  public final Runnable runnable​(ThrowingRunnable runnable)

  Removes checked exceptions from method signature of ThrowingRunnable.

  If runnable throws a checked exception, the exception is caught and passed to handle(Exception), which usually converts it to an unchecked exception, which is then thrown by this method. Null runnable is silently wrapped and causes NullPointerException when executed.

  Typical usage: methodTakingRunnable(Exceptions.sneak().runnable(() -> my_throwing_lambda))

  Parameters:

  runnable - the ThrowingRunnable to be converted, usually a lambda

  Returns:

  converted Runnable free of checked exceptions

• fromDoubleBinaryOperator

  public final DoubleBinaryOperator fromDoubleBinaryOperator​(ThrowingDoubleBinaryOperator operator)

  Removes checked exceptions from method signature of ThrowingDoubleBinaryOperator.

  If operator throws a checked exception, the exception is caught and passed to handle(Exception), which usually converts it to an unchecked exception, which is then thrown by this method. Null operator is silently wrapped and causes NullPointerException when executed.

  Typical usage: methodTakingDoubleBinaryOperator(Exceptions.sneak().fromDoubleBinaryOperator((l, r) -> my_throwing_lambda))

  Parameters:

  operator - the ThrowingDoubleBinaryOperator to be converted, usually a lambda

  Returns:

  converted DoubleBinaryOperator free of checked exceptions

• comparator

  public final <T> Comparator<T> comparator​(ThrowingComparator<T> comparator)

  Removes checked exceptions from method signature of ThrowingComparator.

  If comparator throws a checked exception, the exception is caught and passed to handle(Exception), which usually converts it to an unchecked exception, which is then thrown by this method. Null comparator is silently wrapped and causes NullPointerException when executed.

  Typical usage: methodTakingComparator(Exceptions.sneak().comparator((l, r) -> my_throwing_lambda))

  Type Parameters:

  T - see Comparator

  Parameters:

  comparator - the ThrowingComparator to be converted, usually a lambda

  Returns:

  converted Comparator free of checked exceptions

• closeable

  public final CloseableScope closeable​(AutoCloseable closeable)

  Removes checked exceptions from method signature of AutoCloseable.

  If closeable throws a checked exception, the exception is caught and passed to handle(Exception), which usually converts it to an unchecked exception, which is then thrown by this method. Null closeable is silently wrapped and causes NullPointerException when executed.

  Typical usage: try (var scope = Exceptions.sneak().closeable(openSomething()))

  Parameters:

  closeable - the AutoCloseable to be converted

  Returns:

  converted CloseableScope free of checked exceptions
