Peter Verhas updated LANG-1477:
-------------------------------
Description:
Proposal to implement functional interface conversion functions in the class
{{org.apache.commons.lang3.Functions}} that convert {{FailableXXX}} to {{XXX}}.
For example, the FailableRunnable can be converted with the method:
{code:java}
static <K extends Throwable> Runnable castToRunnable(FailableRunnable<K> s) {
return () -> run(s);
}{code}

For example, the FailableRunnable can be converted with the method:
{code:java}
static <K extends Throwable> Runnable castToRunnable(FailableRunnable<K> s) {
return () -> {
try {
s.run();
} catch (Throwable k) {
rethrow(k);
}
};
}{code}
I believe that these casting methods will have a huge user base for the
application when a lambda expression throws checked exception and is to be used
inside a stream chain. Apache Commons is a well-established library to become
the de-facto standard if it gets implemented.
I will implement the change and will issue a pull request as my free time
allows.
