Class: Parser ​

Defined in: sparql-results/src/parsers/index.ts:10

Parser class for handling query responses from various formats.

This class processes responses from SPARQL endpoints and converts them into standardized formats for further processing. It can handle JSON, XML, CSV, TSV, and Turtle responses, detecting the format either from content-type headers or by attempting to parse the content.

The parser can process:

  • Direct QueryResponse objects (regular fetch response with additional content property with the awaited response content)
  • ResponseSummary objects
  • Error objects
  • Raw response data

It provides methods to access parsed data in standardized formats, error information, and utilities to convert the data for storage or export.
