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.

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

bool JSON_SETTINGS::MigrateFromLegacy ( wxConfigBase *  aLegacyConfig)
virtualinherited

Migrates from wxConfig to JSON-based configuration.

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

◆ registerMigration()

void JSON_SETTINGS::registerMigration ( int  aOldSchemaVersion,

Registers a migration from one schema version to another.

If the schema version in the file loaded from disk is less than the schema version of the JSON_SETTINGS class, migration functions will be called one after the other until the data is up-to-date.

Parameters
aOldSchemaVersionis the starting schema version for this migration
aNewSchemaVersionis the ending schema version for this migration
aMigratoris a function that performs the migration and returns true if successful
