Base Combining Provider

Collation Provider Grooper.Extract

Base collation provider for combining multiple DataInstance results using various methods.

Remarks

The BaseCombiningProvider class defines the core logic for combining the results of multiple extractors within a Data Type.

This class is the foundation for array, group, and other multi-result collation providers. It provides configuration for how results are merged, how confidence is calculated, and how output values are constructed.

Key features:

  • Supports multiple combination strategies via the 'CombineMethod' property.
  • Allows configuration of confidence calculation using the 'ConfidenceMode' property.
  • Supports custom output formatting and group extraction.

Common use cases:

  • Concatenating results from multiple extractors into a single value.
  • Extracting a value from a specific child extractor or group.
  • Summing numeric results.
  • Combining results based on geometric or flow relationships.
