Method Detail

throwing

public static <T,P> Procedure2<T,P> throwing(ThrowingProcedure2<T,P> throwingProcedure2)

Allows a lambda or anonymous inner class that needs to throw a checked exception to be safely wrapped as a Procedure2 that will throw a RuntimeException, wrapping the checked exception that is the cause.

throwing

public static <T1,T2> Procedure2<T1,T2> throwing(ThrowingProcedure2<T1,T2> throwingProcedure,
                                                             Function3<T1,T2,? super Throwable,? extends RuntimeException> rethrow)

Allows a lambda or anonymous inner class that needs to throw a checked exception to be safely wrapped as a Procedure2 that will throw a user specified RuntimeException based on the provided function. The function is passed the current element and the checked exception that was thrown as context arguments.

fromProcedure

public static <T,P> Procedure2<T,P> fromProcedure(Procedure<? super T> procedure)

addToCollection

public static <T> Procedure2<T,Collection<T>> addToCollection()
