Extractor Node

Defines the abstract base class for all extractor nodes in Grooper.

Remarks

The Extractor Node class provides the foundation for all objects that perform data extraction in Grooper.
Extractor nodes are responsible for locating and extracting values, regions, or structured data from document content.

Overview

• Extractor nodes are used to implement the logic for finding and returning Data Instances from a document.
• Each extractor exposes a set of 'Group Names' representing named groups or subfields produced by the extraction logic (for example, named groups in a regular expression).
• The extraction process is performed by implementing the 'Find Instances' method, which returns a collection of Data Instances for a given input.
