public interface CharIterable
extends Iterable<Character>

A type-specific Iterable that strengthens that specification of iterator() and forEach(Consumer).

Note that whenever there exist a primitive consumer in java.util.function (e.g., IntConsumer), trying to access any version of forEach(Consumer) using a lambda expression with untyped arguments will generate an ambiguous method error. This can be easily solved by specifying the type of the argument, as in

    intIterable.forEach((int x) -> { // Do something with x });
 

The same problem plagues, for example, PrimitiveIterator.OfInt.forEachRemaining(java.util.function.IntConsumer).

Warning: Java will let you write “colon” for statements with primitive-type loop variables; however, what is (unfortunately) really happening is that at each iteration an unboxing (and, in the case of fastutil type-specific data structures, a boxing) will be performed. Watch out.

Method Detail

iterator

CharIterator iterator()

Returns a type-specific iterator.

Note that this specification strengthens the one given in Iterable.iterator().

Specified by:

iterator in interface Iterable<Character>

Returns:

a type-specific iterator.

See Also:

Iterable.iterator()

forEach

default void forEach(IntConsumer action)

Performs the given action for each element of this type-specific Iterable until all elements have been processed or the action throws an exception.

Parameters:

action - the action to be performed for each element.

Since:

8.0.0

forEach

@Deprecated
default void forEach(Consumer<? super Character> action)
