#current_version_arrayArray

this package provider does not support package arrays However, There may be multiple versions for a single package so the first element may be a nested array

FIXME: this breaks the semantics of the superclass and needs to get unwound. Since these package providers don't support multipackage they can't put multiple versions into this array. The windows package managers need this in order to uninstall multiple installed version, and they should track that in something like an uninstall_version_array of their own. The superclass does not implement this kind of feature. Doing this here breaks LSP and will create bugs since the superclass will not expect it at all. The current_resource.version also MUST NOT be an array if the package provider is not multipackage. The existing implementation of package_provider.installed_version should probably be what uninstall_version_array is, and then that list should be sorted and last/first'd into the current_resource.version. The current_version_array method was not intended to be overwritten by subclasses (but ruby provides no feature to block doing so -- it is already marked as private).

Returns:

  • (Array)

    current_version(s) as an array
