Document Understanding Activities
Last updated Nov 26, 2024
ExtractorNativeActivity Class
The
ExtractorNativeActivity abstract class adds functionality to the
IExtractorActivity interface and the NativeActivity
abstract class, crucial for creating a NativeActivity for document data
extraction.
Abstract class that implements the
UiPath.DocumentProcessing.Contracts.DataExtraction.IExtractorActivity
interface and the System.Activities.NativeActivity abstract
class.
This class must be implemented in order to construct a
NativeActivity for document data extraction, compatible with
the Data Extraction Scope activity and the document processing
infrastructure.
In order to implement this abstract class, the
Execute(NativeActivityContext
context) method needs to be overridden.
The Data Extraction Scope activity auto-populates all defined InArguments for its child activities. These InArguments include the following information:
- Specific details about the document under extraction, including its original file path, text version, and document object model.
- Details regarding the fields the extractor activity is expected to process, set by the Data Extraction Scope activity in the Configure Extractors wizard.
The OutArgument holds the extraction results. This is made up of an
ExtractorResult object, which contains a
DataPoints list with entries for each successfully identified
requested input field.
Constructors
ExtractorNativeActivity() - The protected default constructor.
Methods
GetCapabilities()- Gets a list of fields the extractor is capable of extracting, for each document type, at design time. This method will only be called at design time, and as such it should not use any InArgument(s).ProvidesCapabilities()- Returns true if the extractor is able to provide a list of capabilities.
Properties
DocumentPathInArgument<string>- The file path of the document.DocumentTextInArgument<string>- The text version of the document.DocumentObjectModelInArgument<UiPath.DocumentProcessing.Contracts.Dom.Document>- The document object model of the document.ExtractorDocumentTypeInArgument<UiPath.DocumentProcessing.Contracts.DataExtraction.ExtractorDocumentType>- The document type information that you want the extractor to use.DocumentBoundsInArgument<UiPath.DocumentProcessing.Contracts.Results.ResultsDocumentBounds>- The page range and bounds that you want the extractor to use.ExtractorResultOutArgument<UiPath.DocumentProcessing.Contracts.DataExtraction.ExtractorResult>- The output of the extractor activity.PersistenceIdstring- The unique, opaque ID that is used by the scope activities in order to correctly track and configure the extractor activity.PredictionIdInArgument<string>- Identifies that the same document is processed in a workflow. It's composed ofDocumentId+JobId.
