AutoFormsParallelRunItemGetterLeadDocument(LEADDocument,object,string,object) Delegate

Summary

Callback to get the LEADDocument instance to run the AutoFormsEngine on.

Syntax

C++/CLI

Python

public delegate void AutoFormsParallelRunItemGetterLeadDocument( 
   ref LEADDocument leadDoc, 
   ref object itemUserData, 
   ref string repositoryName, 
   object getterUserData 
)

public: 
   delegate void AutoFormsParallelRunItemGetterLeadDocument( 
      LEADDocument^ %leadDoc, 
      Object^ %itemUserData, 
      String^ %repositoryName, 
      Object^ getterUserData 
   )

def AutoFormsParallelRunItemGetterLeadDocument(self,leadDoc,itemUserData,repositoryName,getterUserData): 
# leadDoc : LEADDocument&, itemUserData : Object&, repositoryName : String&, getterUserData : Object

Parameters

leadDoc

LEADDocument instance to run the AutoFormsEngine on.

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.
