[Java] Class ParallelLongArrayWithDoubleMapping

java.lang.Object
  groovyx.gpars.extra166y.AbstractParallelAnyArray.LPap
      groovyx.gpars.extra166y.ParallelLongArrayWithDoubleMapping

public abstract class ParallelLongArrayWithDoubleMapping
extends LPap

A prefix view of ParallelLongArray that causes operations to apply to mappings of elements, not to the elements themselves. Instances of this class may be constructed only via prefix methods of ParallelLongArray or its other prefix classes.

Constructor Summary
`ParallelLongArrayWithDoubleMapping(ForkJoinPool ex, int origin, int fence, long[] array)`

Method Summary
`ParallelDoubleArray`	`all()` Returns a new ParallelDoubleArray holding mappings.
`void`	`apply(DoubleProcedure procedure)` Applies the given procedure.
`double`	`max()` Returns the maximum element, or -Double.MAX_VALUE if empty.
`double`	`max(DoubleComparator comparator)` Returns the maximum element, or -Double.MAX_VALUE if empty.
`double`	`min()` Returns the minimum element, or Double.MAX_VALUE if empty.
`double`	`min(DoubleComparator comparator)` Returns the minimum element, or Double.MAX_VALUE if empty.
`double`	`reduce(DoubleReducer reducer, double base)` Returns reduction of mapped elements.
`java.lang.Iterable`	`sequentially()` Returns an Iterable view to sequentially step through mapped elements also obeying bound and filter constraints, without performing computations to evaluate them in parallel.
`double`	`sum()` Returns the sum of elements.
`SummaryStatistics`	`summary(DoubleComparator comparator)` Returns summary statistics.
`SummaryStatistics`	`summary()` Returns summary statistics, using natural comparator.
`ParallelLongArrayWithMapping`	`withIndexedMapping(IntAndDoubleToObject mapper)` Returns an operation prefix that causes a method to operate on mappings of this array using the given mapper that accepts as arguments an element's current index and value (as mapped by preceding mappings, if any), and produces a new value.
`ParallelLongArrayWithDoubleMapping`	`withIndexedMapping(IntAndDoubleToDouble mapper)` Returns an operation prefix that causes a method to operate on mappings of this array using the given mapper that accepts as arguments an element's current index and value (as mapped by preceding mappings, if any), and produces a new value.
`ParallelLongArrayWithLongMapping`	`withIndexedMapping(IntAndDoubleToLong mapper)` Returns an operation prefix that causes a method to operate on mappings of this array using the given mapper that accepts as arguments an element's current index and value (as mapped by preceding mappings, if any), and produces a new value.
`ParallelLongArrayWithLongMapping`	`withMapping(DoubleToLong op)` Returns an operation prefix that causes a method to operate on mapped elements of the array using the given op.
`ParallelLongArrayWithDoubleMapping`	`withMapping(DoubleOp op)` Returns an operation prefix that causes a method to operate on mapped elements of the array using the given op.
`ParallelLongArrayWithMapping`	`withMapping(DoubleToObject op)` Returns an operation prefix that causes a method to operate on mapped elements of the array using the given op.
`ParallelLongArrayWithMapping`	`withMapping(DoubleAndObjectToObject combiner, ParallelArrayWithMapping other)` Returns an operation prefix that causes a method to operate on binary mappings of this array and the other array.
`ParallelLongArrayWithMapping`	`withMapping(DoubleAndDoubleToObject combiner, ParallelDoubleArrayWithDoubleMapping other)` Returns an operation prefix that causes a method to operate on binary mappings of this array and the other array.
