   A rope-like immutable data structure containing bytes.

   A rope-like immutable data structure containing bytes. The goal of this structure is to reduce copying of arrays when concatenating and slicing sequences of bytes, and also providing a thread safe way of working with bytes.

5.  class ClassLoaderObjectInputStream extends ObjectInputStream

   ClassLoaderObjectInputStream tries to utilize the provided ClassLoader to load Classes and falls back to ObjectInputStreams resolver.

6.  sealed abstract class CompactByteString extends ByteString with Serializable

   A compact ByteString.

   A compact ByteString.

   The ByteString is guarantied to be contiguous in memory and to use only as much memory as required for its contents.

7.  class ConcurrentMultiMap[K, V] extends Index[K, V]

   An implementation of a ConcurrentMultiMap Adds/remove is serialized over the specified key Reads are fully concurrent <-- el-cheapo

8.  class Index[K, V] extends AnyRef

9.  final class ManifestInfo extends Extension

   Utility that extracts ManifestInfo#Version information from META-INF/MANIFEST.MF in jar files on the classpath.

   Utility that extracts ManifestInfo#Version information from META-INF/MANIFEST.MF in jar files on the classpath. Note that versions can only be found in ordinary jar files, for example not in "fat jars' assembled from many jar files.

10.  final class MessageBuffer extends AnyRef

    A non thread safe mutable message buffer that can be used to buffer messages inside actors.

11.  final class MessageBufferMap[I] extends AnyRef

    A non thread safe mutable message buffer map that can be used to buffer messages inside actors.

    A non thread safe mutable message buffer map that can be used to buffer messages inside actors.

    I

    (Id type)

12.  final class NanoTimeTokenBucket extends TokenBucket

    Default implementation of TokenBucket that uses System.nanoTime as the time source.

13.  trait PriorityQueueStabilizer[E <: AnyRef] extends AbstractQueue[E]

    PriorityQueueStabilizer wraps a priority queue so that it respects FIFO for elements of equal priority.

14.  final class ReentrantGuard extends ReentrantLock
15.  class StablePriorityBlockingQueue[E <: AnyRef] extends AbstractQueue[E] with PriorityQueueStabilizer[E]

    StablePriorityBlockingQueue is a blocking priority queue that preserves order for elements of equal priority.

16.  class StablePriorityQueue[E <: AnyRef] extends AbstractQueue[E] with PriorityQueueStabilizer[E]

    StablePriorityQueue is a priority queue that preserves order for elements of equal priority.

17.  trait Subclassification[K] extends AnyRef

    Typeclass which describes a classification hierarchy.

    Typeclass which describes a classification hierarchy. Observe the contract between isEqual and isSubclass!

18.  class Switch extends AnyRef

    An atomic switch that can be either on or off

19.  case class Timeout(duration: FiniteDuration) extends Product with Serializable

    Annotations

    @SerialVersionUID()

20.  class TypedMultiMap[T <: AnyRef, K[_ <: T]] extends AnyRef

    An immutable multi-map that expresses the value type as a type function of the key type.

    An immutable multi-map that expresses the value type as a type function of the key type. Create it with a type constructor that expresses the relationship:

    trait Key { type Type = T }
    case class MyValue[T](...)
    
    // type function from Key to MyValue
    type KV[K <: Key] = MyValue[K#Type]
    
    val map = TypedMultiMap.empty[Key, KV]
    
    // a plain Int => String map would use this function:
    type plain[K <: Int] = String
    
    // a map T => T would use this function:
    type identity[T <: AnyRef] = T

    Caveat: using keys which take type parameters does not work due to conflicts with the existential interpretation of Key[_]. A workaround is to define a key type like above and provide a subtype that provides its type parameter as type member Type.

21.  class UUIDComparator extends Comparator[UUID]

    Scala implementation of UUIDComparator in https://github.com/cowtowncoder/java-uuid-generator Apache License 2.0.

22.  final class Unsafe extends AnyRef

    INTERNAL API

    @InternalApi()

23.  final class Version extends Comparable[Version]

    Comparable version information.

    Comparable version information.

    The typical convention is to use 3 digit version numbers major.minor.patch, but 1 or two digits are also supported.

    If no . is used it is interpreted as a single digit version number or as plain alphanumeric if it couldn't be parsed as a number.

    It may also have a qualifier at the end for 2 or 3 digit version numbers such as "1.2-RC1". For 1 digit with qualifier, 1-RC1, it is interpreted as plain alphanumeric.

    It has support for https://github.com/dwijnand/sbt-dynver format with + or - separator. The number of commits from the tag is handled as a numeric part. For example 1.0.0+3-73475dce26 is less than 1.0.0+10-ed316bd024 (3 < 10).

24.  trait WallClock extends AnyRef

    A time source.
