[Java] Class ParallelDoubleArrayWithFilter

java.lang.Object
  groovyx.gpars.extra166y.AbstractParallelAnyArray.DPap
      groovyx.gpars.extra166y.ParallelDoubleArrayWithDoubleMapping
          groovyx.gpars.extra166y.ParallelDoubleArrayWithFilter

public abstract class ParallelDoubleArrayWithFilter
extends ParallelDoubleArrayWithDoubleMapping

A prefix view of ParallelDoubleArray that causes operations to apply only to elements for which a selector returns true. Instances of this class may be constructed only via prefix methods of ParallelDoubleArray or its other prefix classes.

Constructor Summary
ParallelDoubleArrayWithFilter(ForkJoinPool ex, int origin, int fence, double[] array)

 
Method Summary
ParallelDoubleArray allUniqueElements()

Returns a new ParallelDoubleArray containing only unique elements (that is, without any duplicates).
double dget(int i)

boolean hasAllEqualElements(ParallelDoubleArrayWithDoubleMapping other)

Returns true if all elements at the same relative positions of this and other array are equal.
void leafTransfer(int lo, int hi, double[] dest, int offset)

void leafTransferByIndex(int[] indices, int loIdx, int hiIdx, double[] dest, int offset)

ParallelDoubleArrayWithFilter replaceWithGeneratedValue(DoubleGenerator generator)

Replaces elements with results of applying the given generator.
ParallelDoubleArrayWithFilter replaceWithMappedIndex(IntToDouble op)

Replaces elements with the results of applying the given op to their indices.
ParallelDoubleArrayWithFilter replaceWithMappedIndex(IntAndDoubleToDouble op)

Replaces elements with the results of applying the given mapping to each index and current element value.
ParallelDoubleArrayWithFilter replaceWithMapping(DoubleOp op)

Replaces elements with the results of applying the given op to their current values.
ParallelDoubleArrayWithFilter replaceWithMapping(BinaryDoubleOp combiner, ParallelDoubleArrayWithDoubleMapping other)

Replaces elements with results of applying op(thisElement, otherElement).
ParallelDoubleArrayWithFilter replaceWithMapping(BinaryDoubleOp combiner, double[] other)

Replaces elements with results of applying op(thisElement, otherElement).
ParallelDoubleArrayWithFilter replaceWithValue(double value)

Replaces elements with the given value.
ParallelDoubleArrayWithFilter withFilter(DoublePredicate selector)

Returns an operation prefix that causes a method to operate only on elements for which the current selector (if present) and the given selector returns true.
ParallelDoubleArrayWithFilter withFilter(BinaryDoublePredicate selector, ParallelDoubleArrayWithDoubleMapping other)

Returns an operation prefix that causes a method to operate only on elements for which the current selector (if present) and the given binary selector returns true.
ParallelDoubleArrayWithFilter withIndexedFilter(IntAndDoublePredicate selector)

Returns an operation prefix that causes a method to operate only on elements for which the current selector (if present) and the given indexed selector returns true.
