Returns the given argument as a supplier, usefull when called with method reference.

Type Parameters:

T - the type of the object produced by the supplier

Parameters:

supplier - the argument already resolved by the compiler as a supplier

the given argument as a typed function

mute

public static void mute(Lambdas.CheckedRunnable runnable)

Mute a failure.

Parameters:

runnable - the runnable able to throw a CheckedException

unchecked

public static void unchecked(Lambdas.CheckedRunnable runnable)
