ParallelDoubleArrayWithBounds (org.codehaus.gpars)

groovyx.gpars.extra166y.ParallelDoubleArrayWithBounds

A prefix view of ParallelDoubleArray that causes operations to apply only to elements within a given range. Instances of this class may be constructed only via prefix methods of ParallelDoubleArray or its other prefix classes.

Methods
Type	Name and description
`int`	`binarySearch(double target)` Assuming this array is sorted, returns the index of an element equal to given target, or -1 if not present.
`int`	`binarySearch(double target, DoubleComparator comparator)` Assuming this array is sorted with respect to the given comparator, returns the index of an element equal to given target, or -1 if not present.
`ParallelDoubleArrayWithBounds`	`cumulate(DoubleReducer reducer, double base)` Replaces each element with the running cumulation of applying the given reducer.
`ParallelDoubleArrayWithBounds`	`cumulateSum()` Replaces each element with the running sum.
`int`	`indexOf(double target)` Returns the index of some element equal to given target, or -1 if not present.
`double`	`precumulate(DoubleReducer reducer, double base)` Replaces each element with the cumulation of applying the given reducer to all previous values, and returns the total reduction.
`double`	`precumulateSum()` Replaces each element with its prefix sum.
`ParallelDoubleArrayWithBounds`	`sort(DoubleComparator cmp)` Sorts the elements.
`ParallelDoubleArrayWithBounds`	`sort()` Sorts the elements, assuming all elements are Comparable.
`ParallelDoubleArrayWithBounds`	`withBounds(int firstIndex, int upperBound)` Returns an operation prefix that causes a method to operate only on the elements of the array between firstIndex (inclusive) and upperBound (exclusive).

- Method Detail
  - public int binarySearch(double target)
    
    Assuming this array is sorted, returns the index of an element equal to given target, or -1 if not present. If the array is not sorted, the results are undefined.
    Returns:
    the index or -1 if not present
    Parameters:
    target - the element to search for
  - public int binarySearch(double target, DoubleComparator comparator)
    
    Assuming this array is sorted with respect to the given comparator, returns the index of an element equal to given target, or -1 if not present. If the array is not sorted, the results are undefined.
    Returns:
    the index or -1 if not present
    Parameters:
    target - the element to search for
    comparator - the comparator
  - public ParallelDoubleArrayWithBounds cumulate(DoubleReducer reducer, double base)
    
    Replaces each element with the running cumulation of applying the given reducer.
    Returns:
    this (to simplify use in expressions)
    Parameters:
    reducer - the reducer
    base - the result for an empty array
  - public ParallelDoubleArrayWithBounds cumulateSum()
    
    Replaces each element with the running sum.
    Returns:
    this (to simplify use in expressions)
  - public int indexOf(double target)
    
    Returns the index of some element equal to given target, or -1 if not present.
    Returns:
    the index or -1 if not present
    Parameters:
    target - the element to search for
  - public double precumulate(DoubleReducer reducer, double base)
    
    Replaces each element with the cumulation of applying the given reducer to all previous values, and returns the total reduction.
    Returns:
    the total reduction
    Parameters:
    reducer - the reducer
    base - the result for an empty array
  - public double precumulateSum()
    
    Replaces each element with its prefix sum.
    Returns:
    the total sum
  - public ParallelDoubleArrayWithBounds sort(DoubleComparator cmp)
    
    Sorts the elements. Unlike Arrays.sort, this sort does not guarantee that elements with equal keys maintain their relative position in the array.
    Returns:
    this (to simplify use in expressions)
    Parameters:
    cmp - the comparator to use
  - public ParallelDoubleArrayWithBounds sort()
    
    Sorts the elements, assuming all elements are Comparable. Unlike Arrays.sort, this sort does not guarantee that elements with equal keys maintain their relative position in the array.
    throws:
    ClassCastException if any element is not Comparable
    
    Returns:
    this (to simplify use in expressions)
  - public ParallelDoubleArrayWithBounds withBounds(int firstIndex, int upperBound)
    
    Returns an operation prefix that causes a method to operate only on the elements of the array between firstIndex (inclusive) and upperBound (exclusive). The bound arguments are relative to the current bounds. For example pa.withBounds(2, 8).withBounds(3, 5) indexes the 5th (= 2+3) and 6th elements of pa. However, indices returned by methods such as indexOf are with respect to the underlying ParallelDoubleArray.
    Returns:
    operation prefix
    Parameters:
    firstIndex - the lower bound (inclusive)
    upperBound - the upper bound (exclusive)
