public Interface ImmutableSetIterable<T>

Redeclares org.eclipse.collections.api.RichIterable.groupBy, org.eclipse.collections.api.collection.ImmutableCollection.groupBy.

Doc from org.eclipse.collections.api.RichIterable.groupBy.

For each element of the iterable, the function is evaluated and the results of these evaluations are collected into a new multimap, where the transformed value is the key and the original values are added to the same (or similar) species of collection as the source iterable.

Example using a Java 8 method reference:

Multimap<String, Person> peopleByLastName =
    people.groupBy(Person::getLastName);

Redeclares org.eclipse.collections.api.RichIterable.groupByEach, org.eclipse.collections.api.collection.ImmutableCollection.groupByEach.

Doc from org.eclipse.collections.api.RichIterable.groupByEach.

Similar to groupBy(Function), except the result of evaluating function will return a collection of keys for each value.

Doc from org.eclipse.collections.api.RichIterable.partition.

Filters a collection into a PartitionedIterable based on the evaluation of the predicate.

Example using a Java 8 lambda expression:

PartitionIterable<Person> newYorkersAndNonNewYorkers =
    people.partition(person -> person.getAddress().getState().getName().equals("New York"));

Redeclares org.eclipse.collections.api.set.SetIterable.partitionWith, org.eclipse.collections.api.collection.ImmutableCollection.partitionWith.

Doc from org.eclipse.collections.api.RichIterable.partitionWith.

Filters a collection into a PartitionIterable based on the evaluation of the predicate.

Example using a Java 8 lambda expression:

PartitionIterable<Person> newYorkersAndNonNewYorkers =
    people.partitionWith((Person person, String state) -> person.getAddress().getState().getName().equals(state), "New York");

Redeclares org.eclipse.collections.api.set.SetIterable.reject, org.eclipse.collections.api.collection.ImmutableCollection.reject.

Doc from org.eclipse.collections.api.RichIterable.reject.

Returns all elements of the source collection that return false when evaluating of the predicate. This method is also sometimes called filterNot and is the equivalent of calling iterable.select(Predicates.not(predicate)).

Example using a Java 8 lambda expression:

RichIterable<Person> rejected =
    people.reject(person -> person.person.getLastName().equals("Smith"));

Redeclares org.eclipse.collections.api.set.SetIterable.rejectWith, org.eclipse.collections.api.collection.ImmutableCollection.rejectWith.

Doc from org.eclipse.collections.api.RichIterable.rejectWith.

Similar to reject(Predicate), except with an evaluation parameter for the second generic argument in Predicate2.

E.g. return a Collection of Person elements where the person has an age greater than or equal to 18 years

Example using a Java 8 lambda expression:

RichIterable<Person> rejected =
    people.rejectWith((Person person, Integer age) -> person.getAge() < age, Integer.valueOf(18));

@Override

Redeclares org.eclipse.collections.api.set.SetIterable.select, org.eclipse.collections.api.collection.ImmutableCollection.select.

Doc from org.eclipse.collections.api.RichIterable.select.

Returns all elements of the source collection that return true when evaluating the predicate. This method is also commonly called filter.

Example using a Java 8 lambda expression:

RichIterable<Person> selected =
    people.select(person -> person.getAddress().getCity().equals("London"));

Redeclares org.eclipse.collections.api.set.SetIterable.selectInstancesOf, org.eclipse.collections.api.collection.ImmutableCollection.selectInstancesOf.

Doc from org.eclipse.collections.api.RichIterable.selectInstancesOf.

Returns all elements of the source collection that are instances of the Class clazz.

RichIterable<Integer> integers =
    List.mutable.with(new Integer(0), new Long(0L), new Double(0.0)).selectInstancesOf(Integer.class);
