Method Detail

unchecked

public static RuntimeException unchecked(Throwable e)

Rethrows a checked exception as unchecked exception. This method tricks the compiler into thinking the exception is unchecked, rather than wrapping the given exception in a new RuntimeException.

This method never returns. Nevertheless, it specifies a return type so it can be invoked as throw unchecked(e) in contexts where an exception type is syntactically required (e.g. when the enclosing method is non-void).

Parameters:

e - Throwable to be made unchecked.

Returns:

This will never return anything. It's here to trick the compiler.

wrap

public static <T> T wrap(Callable<T> exec)

Tries to call the callable and return the result. If an exception occurs, it will create unchecked exceptions for checked exceptions.

Type Parameters:

T - Type of return parameter.

Parameters:

exec - Callable to execute.

Returns:

result from callable or throws exception.
