Constructor Detail

ParallelLongArrayWithBounds

ParallelLongArrayWithBounds(jsr166y.ForkJoinPool ex,
                            int origin,
                            int fence,
                            long[] array)

Method Detail

withBounds

public abstract ParallelLongArrayWithBounds 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 ParallelLongArray.

Parameters:

firstIndex - the lower bound (inclusive)

upperBound - the upper bound (exclusive)

Returns:

operation prefix

indexOf

public abstract int indexOf(long target)

Returns the index of some element equal to given target, or -1 if not present.

Parameters:

target - the element to search for

Returns:

the index or -1 if not present

binarySearch

public abstract int binarySearch(long 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.

Parameters:

target - the element to search for

Returns:

the index or -1 if not present

binarySearch

public abstract int binarySearch(long target,
                                 Ops.LongComparator 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.

Parameters:

target - the element to search for

comparator - the comparator

Returns:

the index or -1 if not present

cumulate

public abstract ParallelLongArrayWithBounds cumulate(Ops.LongReducer reducer,
                                                     long base)

Replaces each element with the running cumulation of applying the given reducer.

Parameters:

reducer - the reducer

base - the result for an empty array

Returns:

this (to simplify use in expressions)

cumulateSum

public abstract ParallelLongArrayWithBounds cumulateSum()

Replaces each element with the running sum.

Returns:

this (to simplify use in expressions)

precumulate

public abstract long precumulate(Ops.LongReducer reducer,
                                 long base)

Replaces each element with the cumulation of applying the given reducer to all previous values, and returns the total reduction.

Parameters:

reducer - the reducer

base - the result for an empty array

Returns:

the total reduction

precumulateSum

public abstract long precumulateSum()

Replaces each element with its prefix sum.

Returns:

the total sum

sort

public abstract ParallelLongArrayWithBounds sort(Ops.LongComparator cmp)

Sorts the elements. Unlike Arrays.sort, this sort does not guarantee that elements with equal keys maintain their relative position in the array.

Parameters:

cmp - the comparator to use

Returns:

this (to simplify use in expressions)

sort

public abstract ParallelLongArrayWithBounds 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.

Returns:

this (to simplify use in expressions)

Throws:

java.lang.ClassCastException - if any element is not Comparable
