  jsr166y.ForkJoinTask<java.lang.Void>

All Implemented Interfaces:

java.io.Serializable, java.util.concurrent.Future<java.lang.Void>

Enclosing class:

PAS

static final class PAS.FJOMerger
extends jsr166y.RecursiveAction

Performs merging for FJSorter. If big enough, splits Left partition in half; finds the greatest point in Right partition less than the beginning of the second half of Left via binary search; and then, in parallel, merges left half of Left with elements of Right up to split point, and merges right half of Left with elements of R past split point. At leaf, it just sequentially merges. This is all messy to code; sadly we need six versions.
