Method Details

cast

public static <T> Procedure<T> cast(Procedure<T> procedure)

Allows a Java 8 lambda and method to be used in a forEach method without requiring a cast.

println

public static <T> Procedure<T> println(PrintStream stream)

append

public static <T> Procedure<T> append(Appendable appendable)

throwing

public static <T> Procedure<T> throwing(ThrowingProcedure<T> throwingProcedure)

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

throwing

public static <T> Procedure<T> throwing(ThrowingProcedure<T> throwingProcedure,
 Function2<T,? 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 Procedure 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.
