Specifies how to load in memory the master form data found in the repository.
public AutoFormsEngineMasterFormLoadType MasterFormLoadType { get; }
public AutoFormsEngineMasterFormLoadType getMasterFormLoadType();
Public ReadOnly Property MasterFormLoadType() As AutoFormsEngineMasterFormLoadType
Get
public:
property AutoFormsEngineMasterFormLoadType^ MasterFormLoadType
{
AutoFormsEngineMasterFormLoadType^ get()
}
Gets the load type for master form data.
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:
MasterForm
data on demand.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.
