Enum Class PluginInstallUtils.Presence

java.lang.Enum<PluginInstallUtils.Presence>

com.ultikits.ultitools.utils.PluginInstallUtils.Presence

All Implemented Interfaces:

Serializable, Comparable<PluginInstallUtils.Presence>, java.lang.constant.Constable

Enclosing class:

PluginInstallUtils

private static enum PluginInstallUtils.Presence
extends Enum<PluginInstallUtils.Presence>

What a filesystem probe answered, keeping "unknown" out of "no".

File's predicates return false both when the answer is no and when the answer could not be obtained -- an ancestor that cannot be searched, a policy that refuses. Every yes/no question this uninstall asks the filesystem goes through PluginInstallUtils.probe(File) so the two cannot be confused; the sweep table in the pull request lists them.
