groovyx.gpars
[Groovy] Class TransparentParallel

java.lang.Object
  groovyx.gpars.TransparentParallel

final class TransparentParallel

Enhances objects by being mixed-in either within a GParsPool.withPool() block or after enhancement by the ParallelEnhancer through the makeConcurrent() method. It overrides the iterative methods, like each, collect and such to delegate to eachParallel, collectParallel and other parallel iterative methods. The collections returned from collect(), findAll() and grep() are again mixed with a TransparentParallel instance, so their iterative methods are transparently parallel as well.

findAny

final java.lang.Object findAny(groovy.lang.Closure yield)

fold

final java.lang.Object fold(groovy.lang.Closure yield)

fold

final java.lang.Object fold(java.lang.Object seed, groovy.lang.Closure yield)

grep

final java.lang.Object grep(java.lang.Object filter)

groupBy

final java.lang.Object groupBy(groovy.lang.Closure yield)

isConcurrencyActive

boolean isConcurrencyActive()
Indicates, whether the iterative methods like each() or collect() should have a concurrent or a sequential semantics.

isConcurrent

boolean isConcurrent()
Indicates, whether the iterative methods like each() or collect() have been made parallel. Always true once a collection is enhanced through the makeConcurrent() method. The concurrencyActive flag then indicates, whether the enhanced collection has concurrent or the original sequential semantics

max

final java.lang.Object max(groovy.lang.Closure yield)

max

final java.lang.Object max()

min

final java.lang.Object min(groovy.lang.Closure yield)

min

final java.lang.Object min()

setConcurrencyActive

void setConcurrencyActive(boolean flag)
Turns concurrency on and off as needed
Parameters:
flag - True, if the collection processing methods should have parallel semantics, false if they should call the original sequential implementation

split

final java.lang.Object split(groovy.lang.Closure yield)

sum

final java.lang.Object sum()
