Interface LongSetter<T>

Type Parameters:

T - generic type

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface LongSetter<T>

Procedure with a generic and a long argument.

Especially useful for handling setting properties which have a long value.

 class A
 {
   private long value;

   public long getValue()
   {
     return value;
   }

   public void setValue(long value)
   {
     this.value = value;
   }
 }
 // [...]
 LongSetter<A> valueSetter = A::setValue;
 

The other way round, i.e. a LongGetter, is already provided by the standard library: see ToLongFunction.
