canUpgrade

public boolean canUpgrade()

Specified by:

canUpgrade in interface UpgradeableConfig

Returns:

whether or not this config can be updated

upgrade

public UpgradeableConfig upgrade(UpgradeContext upgradeContext)

Description copied from interface: UpgradeableConfig

Return an upgraded config, which may be upgradeable itself. This allows v0 to upgrade to v1, which can then be upgraded to v2, and so on. In this way, as long as each config version knows how to upgrade to the next version, we will be able to upgrade from any old version to the most current version.

Specified by:

upgrade in interface UpgradeableConfig

Parameters:

upgradeContext - context for upgrading

Returns:

the upgraded config
