final def bulkPublisher(fanout: Boolean, maxDocs: Int, err: () => Option[Iterator[T]])(implicit m: Materializer): Publisher[Iterator[T]]

Returns a Reactive Streams publisher of bulks from this cursor.

m

the stream materializer

maxDocs

the maximum number of documents to be retrieved

def fold[A](z: => A, maxDocs: Int)(suc: (A, T) => A)(implicit ec: ExecutionContext): Future[A]

Applies a binary operator to a start value and all elements retrieved by this cursor, going first to last.

Applies a binary operator to a start value and all elements retrieved by this cursor, going first to last.

Type parameters:
A

the result type of the binary operator

import scala.concurrent.ExecutionContext
import reactivemongo.api.Cursor
case class Person(name: String, age: Int)
def foo(cursor: Cursor[Person])(implicit ec: ExecutionContext) =
 cursor.foldWhile(Nil: Seq[Person])((s, p) => Cursor.Cont(s :+ p),
   { (l, e) => println("last valid value: " + l); Cursor.Fail(e) })
Value parameters:
err

The binary operator to be applied when failing to get the next response. Exception or Fail raised within the suc function cannot be recovered by this error handler.

maxDocs

the maximum number of documents to be retrieved (-1 for unlimited).

suc

The binary operator to be applied when the next document is successfully read.

z

the initial value
