All Implemented Interfaces:

CheckConformance.Rule

Enclosing class:

ConformanceRules

public static final class ConformanceRules.BanUnknownDirectThisPropsReferences
extends ConformanceRules.AbstractTypeRestrictionRule

Banned unknown type references of the form "this.prop" unless - it is immediately cast, - it is a @template type (until template type restricts are enabled) or - the value is unused. - the "this" type is unknown (as this is expected to be used with BanUnknownThis which would have already reported the root cause).
