IDtUserProviderEx

Assembly: Dt;

Description

The IDtUserProviderEx interface is used to collect data with the help of custom algorithm.

Inheritance Hierarchy

Comments

A custom algorithm should be implemented in the Fore language and be included in a unit or assembly in the current repository.

This interface, unlike the IDtUserProvider interface, helps to specify the Fore class to implement system interface of custom data provider.

Properties

  Property name Brief description
CustomObject

The CustomObject property returns the object, that is the data source, obtained with help of custom algorithm.
CustomProvider

The CustomProvider property returns the data provider, obtained with help of custom algorithm.
Macro

The Macro property determines the class name implementing custom algorithm of data receiving.
Module

The Module property determines a Fore unit or assembly of the repository where the custom algorithm of data extraction is implemented.

AutoFillFieldsMode The AutoFillFieldsMode property determines the field type detection mode of the data provider.
CalcFieldsErrors The CalcFieldsErrors property returns a collection of errors appeared on calculated fields calculation.
Eof The Eof property returns True if the cursor in the data source is on the last record.
FetchErrors The FetchErrors property returns errors occurred on data import.
FilterIf The FilterIf property returns condition of loading of records from data provider.
StringDataFormat The StringDataFormat property returns settings used on data identification.
