Type Members

  1. abstract class EntryIterator[T, +IterRepr <: IterableSplitter[T]] extends IterableSplitter[T] with SizeMapUtils

    A parallel iterator returning all the entries.

Abstract Value Members

  1. abstract def createNewEntry[B](key: K, value: B): Entry

    Creates new entry to be immediately inserted into the hashtable.

    Creates new entry to be immediately inserted into the hashtable. This method is guaranteed to be called only once and in case that the entry will be added. In other words, an implementation may be side-effecting.

  2. final def ##(): Int

    Equivalent to x.hashCode except for boxed numeric types and null.

    Equivalent to x.hashCode except for boxed numeric types and null. For numerics, it returns a hash value which is consistent with value equality: if two value type instances compare as true, then ## will produce the same hash value for each of them. For null returns a hashcode where null.hashCode throws a NullPointerException.

    returns

    a hash value consistent with ==

  9. final def asInstanceOf[T0]: T0

    Cast the receiver object to be of type T0.

    Cast the receiver object to be of type T0.

    Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expression List(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested type.

    returns

    the receiver object.

  20. final def eq(arg0: AnyRef): Boolean

    Tests whether the argument (that) is a reference to the receiver object (this).

    Tests whether the argument (that) is a reference to the receiver object (this).

    The eq method implements an equivalence relation on non-null instances of AnyRef, and has three additional properties:

    • It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of x.eq(y) consistently returns true or consistently returns false.
    • For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false.
    • null.eq(null) returns true.

    When overriding the equals or hashCode methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

    returns

    true if the argument is a reference to the receiver object; false otherwise.

    Defer to a high-quality hash in scala.util.hashing. The goal is to distribute across bins as well as possible even if a hash code has low entropy at some bits.

    OLD VERSION - quick, but bad for sequence 0-10000 - little entropy in higher bits - since 2003

    h = h ^ (h >>> 14)
