MasterFormLoadType Property

Summary

Specifies how to load in memory the master form data found in the repository.

Syntax

C++/CLI

Java

Python

public AutoFormsEngineMasterFormLoadType MasterFormLoadType { get; }

public AutoFormsEngineMasterFormLoadType getMasterFormLoadType();

public:  
   property AutoFormsEngineMasterFormLoadType^ MasterFormLoadType 
   { 
      AutoFormsEngineMasterFormLoadType^ get() 
   }

MasterFormLoadType # get  (AutoFormsEngine)

Property Value

Gets the load type for master form data.

Remarks

This property is used to control the amount of memory used to hold master form data while maintaining the AutoFormsEngine's speed. The AutoFormsEngine performs the fastest when all master form data are loaded in memory. If the repository contains too many master forms to be loaded in memory, then there are two options:

Load MasterForm data on demand.
Use cache. Cache is a tradeoff between AutoFormsEngine speed and the needed memory. Notice that the cache option works only when FullTextSearchManager is set, otherwise it will work as in the load on demand option.
