AutoFormsParallelRunItemGetterFileName(string,object,string,object) Delegate

Summary

Callback to get the fileName to run the AutoFormsEngine on.

Syntax

C++/CLI

Python

public delegate void AutoFormsParallelRunItemGetterFileName( 
   ref string fileName, 
   ref object itemUserData, 
   ref string repositoryName, 
   object getterUserData 
)

public: 
   delegate void AutoFormsParallelRunItemGetterFileName( 
      String^ %fileName, 
      Object^ %itemUserData, 
      String^ %repositoryName, 
      Object^ getterUserData 
   )

def AutoFormsParallelRunItemGetterFileName(self,fileName,itemUserData,repositoryName,getterUserData): 
# fileName : String&, itemUserData : Object&, repositoryName : String&, getterUserData : Object

Parameters

fileName

Path of the file to run the AutoFormsEngine on it.

itemUserData

Optional object associated with the input item.

repositoryName

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

getterUserData

Optional object that might be passed to the RunParallelPipesOnDemand and then passed to the getter callback.

Remarks

If the getterUserData is used, then apply an appropriate syncing method as multiple getters can be called in parallel threads.
