TrainableExtractorCodeActivity is an abstract class that implements the UiPath.DocumentProcessing.Contracts.Training.ITrainableExtractorActivity interface and the System.Activities.CodeActivity abstract class.

Definition

  • Namespace: UiPath.DocumentProcessing.Contracts.Training
  • Assembly: UiPath.DocumentProcessing.Contracts

Description

Abstract class that implements the UiPath.DocumentProcessing.Contracts.Training.ITrainableExtractorActivity interface and the System.Activities.CodeActivity abstract class.
This class should be implemented in order to construct an CodeActivity for extractors training, compatible with the Train Extractors Scope activity and the document processing infrastructure.

Parameters for training extractor activities

The Train Extractors Scope activity automatically populates all defined InArguments for all child activities. The InArguments include the following information:

  • Data about the document utilized for data extraction, such as the original file path, the text version, and the document object model.
  • Information about each field that should undergo training, anticipated to be discerned and handled by the training activities. These types are determined by the Train Extractors Scope activity after configuring in the Configure Training wizard.

This activity does not have any OutArguments.
