Inheritance¶

Description¶

TJSONIniFile is a descendant of TCustomIniFile that stores configuration data in JSON format instead of traditional ini file format. The JSON structure uses objects for sections and key-value pairs within those objects for the actual configuration entries. This allows for more flexible data storage while maintaining full compatibility with the standard ini file interface.

Properties¶

Member	Visibility	Description
CacheUpdates	public	Controls when changes are written to file
Stream read only	public	Read-only access to the internal stream
