public interface ByteIterable extends java.lang.Iterable<java.lang.Byte>
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
ByteIterator iterator()
Returns a type-specific iterator.- Specified by:
iterator
in interfacejava.lang.Iterable<java.lang.Byte>
- Returns:
- a type-specific iterator.
- See Also:
Iterable.iterator()
- API Notes:
- Note that this specification strengthens the one given in
Iterable.iterator()
.
-
intIterator
default IntIterator intIterator()
Returns a widened primitive iterator on the elements of this iterable.This method is provided for the purpose of APIs that expect only the JDK's primitive iterators, of which there are only
int
,long
, anddouble
.- Returns:
- a widened primitive iterator on the elements of this iterable.
- Since:
- 8.5.0
-
spliterator
default ByteSpliterator spliterator()
Returns a type-specific spliterator on the elements of this iterable.- Specified by:
spliterator
in interfacejava.lang.Iterable<java.lang.Byte>
- 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()
.
-
intSpliterator
default IntSpliterator intSpliterator()
Returns widened primitive spliterator on the elements of this iterable.This method is provided for the purpose of APIs that expect only the JDK's primitive spliterators, of which there are only
int
,long
, anddouble
.- Returns:
- a widened primitive spliterator on the elements of this iterable.
- Since:
- 8.5.0
- Implementation Specification:
- The default implementation widens the spliterator from
spliterator()
.
-
forEach
default void forEach(ByteConsumer 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
default void forEach(java.util.function.IntConsumer action)
Performs the given action for each element of this type-specificIterable
, performing widening primitive casts, 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)
- Implementation Notes:
- Unless the argument is type-specific, this method will introduce an intermediary lambda to perform widening casts. Please use the type-specific overload to avoid this overhead.
-
forEach
@Deprecated default void forEach(java.util.function.Consumer<? super java.lang.Byte> action)
Deprecated.Please use the corresponding type-specific method instead.- Specified by:
forEach
in interfacejava.lang.Iterable<java.lang.Byte>
