trait DimensionalOrdering[A] extends Serializable

DimensionalOrdering is a trait whose instances each represent a strategy for ordering instances of a multidimensional type by a projection on a given dimension.

Abstract Value Members

  1. abstract def compareProjection(dimension: Int)(x: A, y: A): Int

    Returns an integer whose sign communicates how x's projection on a given dimension compares to y's.

    Returns an integer whose sign communicates how x's projection on a given dimension compares to y's.

    Denote the projection of x and y on dimension by x' and y' respectively. The result sign has the following meaning:

    - negative if x' < y' - positive if x' > y' - zero if x' == y'

  2. abstract def dimensions: Int

    How many dimensions type A has.

    Returns an Ordering of A in which the given dimension is the primary ordering criteria.

    Returns an Ordering of A in which the given dimension is the primary ordering criteria. If x and y have the same projection on that dimension, then they are compared on the lowest dimension that is different.
