AddNestedSettings()

void JSON_SETTINGS::AddNestedSettings

Transfers ownership of a given NESTED_SETTINGS to this object.

Can be used to construct a NESTED_SETTINGS without the parent object needing to know about the implementation of the nested object;

Parameters

aSettings	is the settings object to take ownership of
aTarget	is a pointer to update to the passed in settings

Migrate()

bool JSON_SETTINGS::Migrate

(

)

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 )

virtual

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

aLegacyConfig

is a wxConfigBase holding a loaded configuration to migrate

Returns

true if migration was successful

registerMigration()

void JSON_SETTINGS::registerMigration ( int  aOldSchemaVersion, int  aNewSchemaVersion, std::function< bool(void)>  aMigrator  )

protected

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

aOldSchemaVersion	is the starting schema version for this migration
aNewSchemaVersion	is the ending schema version for this migration
aMigrator	is a function that performs the migration and returns true if successful
