Method Summary

Modifier and TypeMethod and Description
public boolean
contains(Object obj)

Overrides org.eclipse.collections.impl.AbstractRichIterable.contains.

Implements org.eclipse.collections.api.RichIterable.contains, java.util.List.contains, java.util.Collection.contains.

Returns true if this list contains the specified element.

public void
each(Procedure<? super T> procedure)

Implements org.eclipse.collections.api.RichIterable.each.

The procedure is executed for each element in the iterable.

public T
get(int index)

Implements org.eclipse.collections.api.list.ListIterable.get, java.util.List.get.

Returns the element at the specified position in this list.

public T
getFirst()

Overrides org.eclipse.collections.impl.list.immutable.AbstractImmutableList.getFirst.

Overrides default java.util.List.getFirst.

Implements org.eclipse.collections.api.RichIterable.getFirst, org.eclipse.collections.api.list.ListIterable.getFirst.

Gets the first element of this collection.

public T
getLast()

Overrides org.eclipse.collections.impl.list.immutable.AbstractImmutableList.getLast.

Overrides default java.util.List.getLast.

Implements org.eclipse.collections.api.RichIterable.getLast, org.eclipse.collections.api.list.ListIterable.getLast.

Gets the last element of this collection.

public T
getOnly()

Overrides default org.eclipse.collections.api.RichIterable.getOnly.

Returns the element if the iterable has exactly one element.

public ImmutableList<T>
newWith(T newItem)

Implements org.eclipse.collections.api.list.ImmutableList.newWith, org.eclipse.collections.api.collection.ImmutableCollection.newWith.

This method is similar to the with method in MutableCollection with the difference that a new copy of this collection with the element appended will be returned.

public int
size()

Implements org.eclipse.collections.api.RichIterable.size, java.util.List.size, java.util.Collection.size.

Returns the number of elements in this list.

public ImmutableList<T>
toReversed()

Overrides org.eclipse.collections.impl.list.immutable.AbstractImmutableList.toReversed.

Implements org.eclipse.collections.api.list.ImmutableList.toReversed.

Returns a new ReversibleIterable in reverse order.

public boolean contains(Object obj)

Overrides org.eclipse.collections.impl.AbstractRichIterable.contains.

Implements org.eclipse.collections.api.RichIterable.contains, java.util.List.contains, java.util.Collection.contains.

Doc from java.util.List.contains.

Returns true if this list contains the specified element. More formally, returns true if and only if this list contains at least one element e such that Objects.equals(o, e).

public void each(Procedure<? super T> procedure)

Implements org.eclipse.collections.api.RichIterable.each.

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

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).
