[Java] Class ParallelArrayWithLongMapping

java.lang.Object
  groovyx.gpars.extra166y.AbstractParallelAnyArray.OPap
      groovyx.gpars.extra166y.ParallelArrayWithLongMapping

public abstract class ParallelArrayWithLongMapping
extends OPap

A prefix view of ParallelArray 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 ParallelArray or its other prefix classes.

Constructor Summary
`ParallelArrayWithLongMapping(ForkJoinPool ex, int origin, int fence, java.lang.Object[] array)`

Method Summary
`ParallelLongArray`	`all()` Returns a new ParallelLongArray holding mappings.
`void`	`apply(LongProcedure procedure)` Applies the given procedure.
`long`	`max()` Returns the maximum element, or Long.MIN_VALUE if empty.
`long`	`max(LongComparator comparator)` Returns the maximum element, or Long.MIN_VALUE if empty.
`long`	`min()` Returns the minimum element, or Long.MAX_VALUE if empty.
`long`	`min(LongComparator comparator)` Returns the minimum element, or Long.MAX_VALUE if empty.
`long`	`reduce(LongReducer reducer, long 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.
`long`	`sum()` Returns the sum of elements.
`SummaryStatistics`	`summary(LongComparator comparator)` Returns summary statistics.
`SummaryStatistics`	`summary()` Returns summary statistics, using natural comparator.
`ParallelArrayWithMapping`	`withIndexedMapping(IntAndLongToObject 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.
`ParallelArrayWithDoubleMapping`	`withIndexedMapping(IntAndLongToDouble 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.
`ParallelArrayWithLongMapping`	`withIndexedMapping(IntAndLongToLong 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.
`ParallelArrayWithDoubleMapping`	`withMapping(LongToDouble op)` Returns an operation prefix that causes a method to operate on mapped elements of the array using the given op.
`ParallelArrayWithLongMapping`	`withMapping(LongOp op)` Returns an operation prefix that causes a method to operate on mapped elements of the array using the given op.
`ParallelArrayWithMapping`	`withMapping(LongToObject op)` Returns an operation prefix that causes a method to operate on mapped elements of the array using the given op.
`ParallelArrayWithMapping`	`withMapping(LongAndObjectToObject combiner, ParallelArrayWithMapping other)` Returns an operation prefix that causes a method to operate on binary mappings of this array and the other array.
`ParallelArrayWithMapping`	`withMapping(LongAndDoubleToObject combiner, ParallelDoubleArrayWithDoubleMapping other)` Returns an operation prefix that causes a method to operate on binary mappings of this array and the other array.
`ParallelArrayWithMapping`	`withMapping(LongAndLongToObject combiner, ParallelLongArrayWithLongMapping other)` Returns an operation prefix that causes a method to operate on binary mappings of this array and the other array.
