Run the registered extension upgrade methods on an object

For each extension recorded in the object's @extensions slot (processed innermost-first) whose installed package version is newer than the recorded stamp (or whose stamp is missing), calls the extension's upgrade method if one is registered, then records the installed version as the new stamp. The core mizer upgrade is not run here; see upgrade.MizerParams().

Usage

runExtensionUpgrades(params)

Arguments

params

A MizerParams object.

Value

The object with extension migrations applied and stamps refreshed.

Details

Extension upgrade methods are looked up with getS3method("upgrade", name, optional = TRUE), must perform only their own migration, must be idempotent, and must not call NextMethod().
