Class: Fontisan::Binary::BaseRecord

Inherits:
BinData::Record
  • Object

Defined in:
lib/fontisan/binary/base_record.rb

Overview

Base class for all BinData record definitions

Provides common configuration for OpenType binary structures:

  • Big-endian byte order (OpenType standard)

  • Common helper methods

All table parsers and binary structures should inherit from this class to ensure consistent behavior across the codebase.

Examples:

Defining a simple structure

class MyTable < Binary::BaseRecord
  uint16 :version
  uint16 :count
end
