Modifier and Type	Method	Description
static <R> Supplier<R>	CheckedSupplier.safe(CheckedSupplier<R> supplierThatCanFailedWithACheckedException)	Wraps a CheckedSupplier (basically a lambda with no arguments that returns a result and which throws a Checked Exception) by returning a new Supplier instance The returned Supplier.get() method delegates directly to the get() and catches any thrown checked Exception's and rethrows them as a CheckedExceptionRethrownException Unless you provide a context-message (using safe(String, CheckedSupplier) then any caught checked Exception's message also becomes the CheckedExceptionRethrownException's message. Any RuntimeException's thrown aren't caught and the calling code will receive the original RuntimeException thrown. Usage example: Let's say we have a method called someOperation that cannot change, but which accepts a Supplier with the purpose of the calling the Supplier.get().
