Class: Fontisan::Binary::BaseRecord

Inherits:

BinData::Record

• Object
• BinData::Record
• Fontisan::Binary::BaseRecord

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
