Abstract class that implements the
UiPath.DocumentProcessing.Contracts.DataExtraction.IExtractorActivity interface and the
System.Activities.CodeActivity abstract class.
This class is implemented in order to construct a
CodeActivity for document data extraction, compatible with the Data Extraction Scope activity and the document processing infrastructure.
In order to implement this abstract class, the
context) method needs to be overridden.
All the defined InArguments are automatically populated by the Data Extraction Scope activity for all child activities.
The InArguments contain:
- Information about the document that is to be classified, specifically the original file path, the text version, and the document object model.
- Information about the fields expected to be understood and processed by the classifier activity. These document types are set by the Data Extraction Scope activity after their configuration in the Configure Extractors wizard of the scope activity.
The OutArgument contains the extraction results, in an
ExtractorResult object, with as many entries in the
DataPoints list as successfully identified requested input fields.
ExtractorCodeActivity()- A protected default constructor
DocumentPathInArgument<string> - The file path to 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 the extractor takes into account.
DocumentBoundsInArgument<UiPath.DocumentProcessing.Contracts.Results.ResultsDocumentBounds> - The page range and bounds that the extractor takes into account.
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.
