RunParallelPipesForList(List<RasterImage>,AutoFormsParallelRunResultRasterImageCallback,List<object>,List<string>,int) Method

Summary

Runs the AutoFormsEngine on a list of RasterImage instances in parallel.

Syntax

C++/CLI

Python

public void RunParallelPipesForList( 
   List<RasterImage> forms, 
   AutoFormsParallelRunResultRasterImageCallback callback, 
   List<object> itemsUserData, 
   List<string> repositoryNames, 
   int pipesCount 
)

public:  
   void RunParallelPipesForList( 
      List<RasterImage^>^ forms, 
      AutoFormsParallelRunResultRasterImageCallback^ callback, 
      List<Object^>^ itemsUserData, 
      List<String^>^ repositoryNames, 
      Int32 pipesCount 
   )

def RunParallelPipesForList(self,forms,callback,itemsUserData,repositoryNames,pipesCount):

Parameters

forms

List of RasterImage instances.

callback

Callback for each input image after processing.

itemsUserData

Optional list of custom data objects associated to each image.

repositoryNames

Optional List. If the corresponding repository name of item is not null, then RunParallelPipesForList uses it in place of the current value of FullTextSearchRepositoryName.

pipesCount

Number of parallel threads used to consume the input data.
