reduce(f: (A, A) => A): Ascala.collection.IterableOnceExtensionMethodsreduce[B >: A](op: (B, B) => B): Bscala.collection.IterableOnceOps

Applies the given binary operator op to all elements of this collection.

reduce[T, R >: T](futures: IterableOnce[Future[T]])(op: (R, T) => R)(implicit executor: ExecutionContext): Future[R]scala.concurrent.Future

Initiates a non-blocking, asynchronous, fold over the supplied futures where the fold-zero is the result value of the first Future in the collection.

reduceLeft(f: (A, A) => A): Ascala.collection.IterableOnceExtensionMethodsreduceOption(f: (A, A) => A): Option[A]scala.collection.IterableOnceExtensionMethods (A, A) => A): Ascala.collection.IterableOnceExtensionMethods >: A](op: (B, A) => B): Bscala.collection.IterableOnceOps

Applies the given binary operator op to all elements of this collection, going left to right.

>: A](op: (B, B) => B): Option[B]scala.collection.IterableOnceOps

If this collection is nonempty, reduces it with the given binary operator op.

>: A](op: (A, B) => B): Bscala.collection.IterableOnceOps

Applies the given binary operator op to all elements of this collection, going right to left.

R >: T](futures: Iterable[Future[T]])(op: (R, T) => R)(implicit executor: ExecutionContext): Future[R]scala.concurrent.Future

Initiates a non-blocking, asynchronous, left reduction over the supplied futures where the zero is the result value of the first Future.

If this collection is nonempty, reduces it with the given binary operator op, going left to right.

>: A](op: (A, B) => B): Option[B]scala.collection.IterableOnceOps

If this collection is nonempty, reduces it with the given binary operator op, going right to left.

InputStream, bufferSize: Int, reset: () => Source, close: () => Unit)(implicit codec: Codec): BufferedSourcescala.io.Source

Reads data from inputStream with a buffered reader, using the encoding in implicit parameter codec.

B](key: A => K)(f: A => B)(reduce: (B, B) => B): Map[K, B]scala.collection.IterableOps

Partitions this iterable collection into a map according to a discriminator function key. All the values that have the same discriminator are then transformed by the f function and then reduced into a single value with the reduce function.

Expr[T])(using Quotes): Expr[T]scala.quoted.Expr Term): Option[Term]scala.quoted.Quotes.reflectModule.TermModule Boolean extension on extension (self: TypeRepr)scala.quoted.Quotes.reflectModule.TypeReprMethods

class

BufferedSource(inputStream: InputStream, bufferSize: Int)(implicit val codec: Codec) extends Sourcescala.io

This object provides convenience methods to create an iterable representation of a source file.
