Class TakeIterable<T>

  • All Implemented Interfaces:
    java.lang.Iterable<T>, InternalIterable<T>, LazyIterable<T>, RichIterable<T>
    public class TakeIterable<T>
extends AbstractLazyIterable<T>
    Iterates over the first count elements of the adapted Iterable or the full size of the adapted iterable if the count is greater than the length of the receiver.

    • Method Detail

      • each

        public void each​(Procedure<? super T> procedure)
        Description copied from interface: RichIterable
        The procedure is executed for each element in the iterable.

        Example using a Java 8 lambda expression: 

         people.each(person -> LOGGER.info(person.getName()));
        This method is a variant of InternalIterable.forEach(Procedure) that has a signature conflict with Iterable.forEach(java.util.function.Consumer).
        See Also:
        InternalIterable.forEach(Procedure), Iterable.forEach(java.util.function.Consumer)

      • forEachWithIndex

        public void forEachWithIndex​(ObjectIntProcedure<? super T> procedure)
        Description copied from interface: InternalIterable
        Iterates over the iterable passing each element and the current relative int index to the specified instance of ObjectIntProcedure.

        Example using a Java 8 lambda: 

         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());
     }
 });
        Specified by:
        forEachWithIndex in interface InternalIterable<T>
        Overrides:
        forEachWithIndex in class AbstractRichIterable<T>

      • forEachWith

        public <P> void forEachWith​(Procedure2<? super T,​? super P> procedure,
                            P parameter)
        Description copied from interface: InternalIterable
        The procedure2 is evaluated for each element in the iterable with the specified parameter provided as the second argument.

        Example using a Java 8 lambda: 

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

        Example using an anonymous inner class: 

         people.forEachWith(new Procedure2<Person, Person>()
 {
     public void value(Person person, Person other)
     {
         if (person.isRelatedTo(other))
         {
              LOGGER.info(person.getName());
         }
     }
 }, fred);
        Specified by:
        forEachWith in interface InternalIterable<T>
        Overrides:
