ExtractorAsyncCodeActivity Class
Document Understanding Activities
Last updated Oct 8, 2024
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
DocumentPath
InArgument<string>
- The file path of the document.DocumentText
InArgument<string>
- The text version of the document.DocumentObjectModel
InArgument<UiPath.DocumentProcessing.Contracts.Dom.Document>
- The document object model of the document.ExtractorDocumentType
InArgument<UiPath.DocumentProcessing.Contracts.DataExtraction.ExtractorDocumentType>
- The document type information that you want the extractor to use.DocumentBounds
InArgument<UiPath.DocumentProcessing.Contracts.Results.ResultsDocumentBounds>
- The page range and bounds that you want the extractor to use.ExtractorResult
OutArgument<UiPath.DocumentProcessing.Contracts.DataExtraction.ExtractorResult>
- The output of the extractor activity.PersistenceId
string
- The unique, opaque ID that is used by the scope activities in order to correctly track and configure the extractor activity.PredictionId
InArgument<string>
- Identifies that the same document is processed in a workflow. It's composed ofDocumentId
+JobId
.
