public interface BooleanIterable extends java.lang.Iterable<java.lang.Boolean>
A type-specificIterable
that strengthens that specification ofiterator()
andforEach(Consumer)
.Note that whenever there exist a primitive consumer in
java.util.function
(e.g.,IntConsumer
), trying to access any version offorEach(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 inintIterable.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 offastutil
type-specific data structures, a boxing) will be performed. Watch out.- See Also:

Method Detail
-
iterator
BooleanIterator iterator()
Returns a type-specific iterator.- Specified by:
iterator
in interfacejava.lang.Iterable<java.lang.Boolean>
- Returns:
- a type-specific iterator.
- See Also:
Iterable.iterator()
- API Notes:
- Note that this specification strengthens the one given in
Iterable.iterator()
.
-
spliterator
default BooleanSpliterator spliterator()
Returns a type-specific spliterator on the elements of this iterable.- Specified by:
spliterator
in interfacejava.lang.Iterable<java.lang.Boolean>
- Returns:
- a type-specific spliterator on the elements of this iterable.
- Since:
- 8.5.0
- API Notes:
- Note that this specification strengthens the one given in
Iterable.spliterator()
.
-
forEach
default void forEach(BooleanConsumer action)
Performs the given action for each element of this type-specificIterable
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
- See Also:
Iterable.forEach(java.util.function.Consumer)
- API Notes:
- Implementing classes should generally override this method, and take the default implementation of the other overloads which will delegate to this method (after proper conversions).
-
forEach
@Deprecated default void forEach(java.util.function.Consumer<? super java.lang.Boolean> action)
Deprecated.Please use the corresponding type-specific method instead.- Specified by:
forEach
in interfacejava.lang.Iterable<java.lang.Boolean>
