Peter Verhas commented on LANG-1477:
------------------------------------
Yes, and no. This is the functionality I was looking for, but the
implementation is copy-paste. The same structure already exists in the static
method {{Functions.run(FailableRunnable<T> pRunnable)}}. Therefore the
implementation of the functions has to be
{code:java}
static <K extends Throwable> Runnable castToRunnable(FailableRunnable<K> s) {
return () -> run(s);
}
{code}
And when I realized that the implementation is so simple, I am now less
convinced that we need this {{asRunnable(FailableRunnable<T> pRunnable)}}
function /and the similar others/ at all.
Even though I suggested this change in the first place I would vote not to
implement it into the class {{Functions}} increasing the footprint of the API.
Instead, I would go for extending the documentation explaining that the already
available methods, like {{run(FailableRunnable<T> pRunnable)}} can be used as
{{()->run(pRunnable)}} to convert a {{FailableRunnable}} to a {{Runnable}}.

> 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}
