    • Method Detail

      • throwAsUncheckedException

        public static RuntimeException throwAsUncheckedException​(Throwable t)
        Throw the supplied Throwable, masked as an unchecked exception.

        The supplied Throwable will not be wrapped. Rather, it will be thrown as is using an exploit of the Java language that relies on a combination of generics and type erasure to trick the Java compiler into believing that the thrown exception is an unchecked exception even if it is a checked exception.


        This method should be used sparingly.

        t - the Throwable to throw as an unchecked exception; never null
        this method always throws an exception and therefore never returns anything; the return type is merely present to allow this method to be supplied as the operand in a throw statement
      • readStackTrace

        public static String readStackTrace​(Throwable throwable)
        Read the stacktrace of the supplied Throwable into a String.
