Detailed Description

NESTED_SETTINGS is a JSON_SETTINGS that lives inside a JSON_SETTINGS.

Instead of being backed by a JSON file on disk, it loads and stores to its parent.

◆ Migrate()

bool JSON_SETTINGS::Migrate ( )
inherited

Migrates the schema of this settings from the version in the file to the latest version.

Schema migration doesn't need to be used every time a setting is added! This is intended to be more of an "escape hatch" in the event that we decide to move settings around or make other changes to a settings file format that can't simply be handled by loading a new default

Returns
true if migration was successful

◆ MigrateFromLegacy()

bool JSON_SETTINGS::MigrateFromLegacy ( wxConfigBase *  aLegacyConfig)

Should be implemented by any subclasses of JSON_SETTINGS that map to a legacy (wxConfig-based) config file.

Parameters
aLegacyConfigis a wxConfigBase holding a loaded configuration to migrate
Returns
true if migration was successful
