Class AcDbPatParser

Parser for AutoCAD PAT text content.

This parser follows a best-effort strategy:

• valid patterns are still returned when some rows are malformed;
• non-fatal problems are collected into AcDbPatDocument.issues;
• PAT line numbers are preserved in parsed descriptors for diagnostics.

Typical usage:

• instantiate once and call parse for each PAT payload;
• or call the convenience static AcDbPatParser.parse method.
