  1. implicit final class AwesomeBitSet extends AnyVal

  3. class BloomFilter[T] extends (T) ⇒ Boolean with Serializable

    A BloomFilter is an approximate set that sometimes gives false positives.

    A BloomFilter is an approximate set that sometimes gives false positives. That is, if bf(x) returns true, then it might have been added to the set. If it returns false, then it definitely has not. This is useful for caching and approximation.

  35. object partition extends UFunc

    Creates a copy of the array with its elements rearranged in such a way that the value of the element in kth position is in the position it would be in a sorted array.

    Creates a copy of the array with its elements rearranged in such a way that the value of the element in kth position is in the position it would be in a sorted array. All elements smaller than the kth element are moved to the start of the array, all greater are moved to the end. Equal elements will be on the immeditate left or right. The ordering of the elements in the two partitions is undefined.

    Based on the numpy method of the same name. Docs lifted from numpy

    Quickselect for linear-time medians, etc. See scala.util.Sorting and breeze.util.Sorting

Deprecated Value Members

  1. object quickSelectImpl extends UFunc

    quickSelectImpl does not clone the input array before doing a quickSelect-sort but instead swaps in place, and therefore, allows other functions to access the intermediate results of the sorting procedure.

    quickSelectImpl does not clone the input array before doing a quickSelect-sort but instead swaps in place, and therefore, allows other functions to access the intermediate results of the sorting procedure.

    After quickSelectImpl is run, it is guaranteed that the input array will be swapped around such that every number left of position will be equal or smaller than the element at position, and every number right of position will be equal or larger than the element at position.

    This can be useful when further using the intermediate results downstream. For example, appending an element or updating an element to an array which has already been through quickSelectImpl and then re-calculating quickSelectImpl will be faster than applying quickSelectImpl de-novo to the original unsorted array.
