java.lang.Object
io.reactivex.rxjava4.exceptions.Exceptions
public final class Exceptions extends Object
Utility class to help propagate checked exceptions and rethrow exceptions designated as fatal.

  • Method Details

    • propagate

      @NonNull public static @NonNull RuntimeException propagate(@NonNull @NonNull Throwable t)
      Convenience method to throw a RuntimeException and Error directly or wrap any other exception type into a RuntimeException.
      Parameters:
      t - the exception to throw directly or wrapped
      Returns:
      because propagate itself throws an exception or error, this is a sort of phantom return value; propagate does not actually return anything

    • throwIfFatal

      public static void throwIfFatal(@NonNull @NonNull Throwable t)
      Throws a particular Throwable only if it belongs to a set of "fatal" error varieties. These varieties are as follows:
      • VirtualMachineError
      • ThreadDeath
      • LinkageError
      This can be useful if you are writing an operator that calls user-supplied code, and you want to notify subscribers of errors encountered in that code by calling their onError methods, but only if the errors are not so catastrophic that such a call would be futile, in which case you simply want to rethrow the error.
      Parameters:
      t - the Throwable to test and perhaps throw
