Method Details

with

public QuintupletonList<T> with(T value)

Description copied from interface: MutableCollection

This method allows mutable and fixed size collections the ability to add elements to their existing elements. In order to support fixed size a new instance of a collection would have to be returned taking the elements of the original collection and appending the new element to form the new collection. In the case of mutable collections, the original collection is modified, and is returned. In order to use this method properly with mutable and fixed size collections the following approach must be taken:

 MutableCollection<String> list = list.with("1");
 list = list.with("2");
 return list;
 

In the case of FixedSizeCollection a new instance of MutableCollection will be returned by with, and any variables that previously referenced the original collection will need to be redirected to reference the new instance. For other MutableCollection types you will replace the reference to collection with the same collection, since the instance will return "this" after calling add on itself.

Description copied from interface: RichIterable

The procedure is executed for each element in the iterable.

 people.forEachWithIndex((Person person, int index) -> LOGGER.info("Index: " + index + " person: " + person.getName()));
 

Example using an anonymous inner class:

 people.forEachWithIndex(new ObjectIntProcedure<Person>()
 {
     public void value(Person person, int index)
     {
         LOGGER.info("Index: " + index + " person: " + person.getName());

Example using a Java 8 lambda:

 people.forEachWith((Person person, Person other) ->
     {
         if (person.isRelatedTo(other))
         {
              LOGGER.info(person.getName());
         }
     }, fred);

 {
     public void value(Person person, Person other)
     {
         if (person.isRelatedTo(other))
