Document Understanding Activities

ExtractorAsyncCodeActivity Class
ExtractorAsyncCodeActivity abstract class, essential for creating an
AsyncCodeActivity for data extraction, implements the
IExtractorActivity interface and AsyncCodeActivity
abstract class.
- Namespace:
UiPath.DocumentProcessing.Contracts.DataExtraction - Assembly:
UiPath.DocumentProcessing.Contracts
An abstract class that implements the
UiPath.DocumentProcessing.Contracts.DataExtraction.IExtractorActivity interface and the System.Activities.AsyncCodeActivity abstract class.
This class must be implemented in order to construct a
AsyncCodeActivity for data extraction, compatible with the Data Extraction Scope activity and the document processing infrastructure.
In order to implement this abstract class, the
BeginExecute() and EndExecute() methods need to be overridden.
The Data Extraction Scope activity auto-populates all defined InArguments for its child activities. Included in these InArguments are the following information:
- Information about the document awaiting data extraction. This includes the original file path, the text format, and the document object model.
- Details about the fields the classifier activity is expected to understand and process. These types are configured via the Data Extraction Scope activity in the Configure Extractors wizard.
The OutArgument houses the extraction results in an
ExtractorResult
object, which contains a list of DataPoints for every successfully
identified requested input field.
Constructors
ExtractorAsyncCodeActivity() - 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.
