ClassifierAsyncCodeActivity Class
Document Understanding Activities
Last updated Oct 8, 2024
ClassifierAsyncCodeActivity Class
The
ClassifierAsyncCodeActivity
abstract class, pivotal for
establishing a CodeActivity
for document classification, implements the
IClassifierActivity
interface and the
Async.CodeActivity
abstract class.
- Namespace:
UiPath.DocumentProcessing.Contracts.Classification
- Assembly:
UiPath.DocumentProcessing.Contracts
An abstract class that implements the
UiPath.DocumentProcessing.Contracts.Classification.IClassifierActivity
interface and the System.Activities.Async.CodeActivity
abstract
class.
This class must be implemented in order to construct a
CodeActivity
for document classification that is compatible with the Classify Document
Scope
activity and the document processing infrastructure.
In order to implement this abstract class, the
BeginExecute()
and
EndExecute()
methods need to be overridden.
Each InArgument defined is auto-populated by the Classify Document Scope activity for its other child activities. The InArguments contain the following data:
- Data about the document ready for classification, including the file path, the text format, and the document model.
- Data concerning the document types the classifier activity must comprehend and handle, configured via Classify Document Scope in the Configure Classifiers wizard.
The OutArgument holds a list of classification outcomes in a
ClassifierResult
. Take the following examples:
- A classifier distinguishing a full file as either contract or annex should have
one entry in
Classifications
, representative of the highest confidence classification. - If a classifier identifies file parts as contract or annex, the
ClassifierResult
should hold disjunctive classifications and associatedResultsDocumentBounds
.
Constructors
ClassifierAsyncCodeActivity()
- The protected default
constructor.
Methods
GetCapabilities()
- Retrieves, at design time, a list of document types the classifier is capable of classifying. This method is called only at design time, and as such it should not use any InArgument(s).ProvidesCapabilities()
- Returns true if the classifier is able to provide a list of capabilities.
Properties
DocumentPath
InArgument<string>
- The path to the document file.DocumentText
InArgument<string>
- The text version of the document.DocumentObjectModel
InArgument<UiPath.DocumentProcessing.Contracts.Dom.Document>
- The document object model of the document.DocumentTypes
InArgument<UiPath.DocumentProcessing.Contracts.Classification.ClassifierDocumentType[]>
- The document type information that you want the classifier to take into account.PersistenceId
string
- The unique, opaque ID that is used by the scope activities in order to correctly track and configure the classifier activity.ClassifierResult
OutArgument<UiPath.DocumentProcessing.Contracts.Classification.ClassifierResult>
- The output of the classifier activity.PredictionId
InArgument<string>
- Identifies that the same document is processed in a workflow. It's composed ofDocumentId
+JobId
.
