RunParallelPipesForList(List<LEADDocument>,AutoFormsParallelRunResultLEADDocumentCallback,List<object>,List<string>,int) Method

Summary

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

Syntax

C++/CLI

Python

public void RunParallelPipesForList( 
   List<LEADDocument> leadDocs, 
   AutoFormsParallelRunResultLEADDocumentCallback callback, 
   List<object> itemsUserData, 
   List<string> repositoryNames, 
   int pipesCount 
)

public:  
   void RunParallelPipesForList( 
      List<LEADDocument^>^ leadDocs, 
      AutoFormsParallelRunResultLEADDocumentCallback^ callback, 
      List<Object^>^ itemsUserData, 
      List<String^>^ repositoryNames, 
      Int32 pipesCount 
   )

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

Parameters

leadDocs

List of LEADDocument instances.

callback

Callback called for each input document after processing.

itemsUserData

Optional list of custom data objects associated to each LEADDocument instance.

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.
