forEach

Constructor Detail

FlatCollectIterable

public FlatCollectIterable(java.lang.Iterable<T> newAdapted,
                   com.gs.collections.api.block.function.Function<? super T,? extends java.lang.Iterable<V>> function)

Method Detail

each

public void each(com.gs.collections.api.block.procedure.Procedure<? super V> procedure)

Description copied from interface: com.gs.collections.api.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()));
 

Example using an anonymous inner class:

 people.each(new Procedure()
 {
     public void value(Person 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(com.gs.collections.api.block.procedure.primitive.ObjectIntProcedure<? super V> objectIntProcedure)

Description copied from interface: com.gs.collections.api.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()
 {
     public void value(Person person, int index)
     {
         LOGGER.info("Index: " + index + " person: " + person.getName());
     }
 });
 

Specified by:

forEachWithIndex in interface com.gs.collections.api.InternalIterable<V>

Overrides:

forEachWithIndex in class AbstractRichIterable<V>

forEachWith

public <P> void forEachWith(com.gs.collections.api.block.procedure.Procedure2<? super V,? super P> procedure,
                   P parameter)

Description copied from interface: com.gs.collections.api.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()
 {
     public void value(Person person, Person other)
     {
         if (person.isRelatedTo(other))
         {
              LOGGER.info(person.getName());
         }
     }
 }, fred);

forEachWith in interface com.gs.collections.api.InternalIterable<V>

Overrides:

forEachWith in class AbstractRichIterable<V>

detect

public V detect(com.gs.collections.api.block.predicate.Predicate<? super V> predicate)

Description copied from interface: com.gs.collections.api.RichIterable

Returns the first element of the iterable for which the predicate evaluates to true or null in the case where no element returns true. This method is commonly called find.

Example using a Java 8 lambda expression:

 Person person =
     people.detect(person -> person.getFirstName().equals("John") && person.getLastName().equals("Smith"));
 

Example using an anonymous inner class:

 Person person =
     people.detect(new Predicate<Person>()
     {
         public boolean value(Person person)
         {
             return person.getFirstName().equals("John") && person.getLastName().equals("Smith");
         }
     });
