      • getParent

        public VmObjectLike getParent()
        Description copied from class: VmObjectLike
        Returns the parent object in the prototype chain. For each concrete subclass X of VmOwner, the exact return type of this method is `X|VmTyped`.
        Specified by:
        getParent in class VmObjectLike

      • hasMember

        public boolean hasMember​(java.lang.Object key)
        Description copied from class: VmObjectLike
        Always prefer this method over `getMembers().containsKey(key)`.
        Specified by:
        hasMember in class VmObjectLike

      • getMembers

        public org.graalvm.collections.UnmodifiableEconomicMap<java.lang.Object,​ObjectMember> getMembers()
        Description copied from class: VmObjectLike
        Returns the declared members of this object.
        Specified by:
        getMembers in class VmObjectLike

      • getCachedValue

        public @Nullable java.lang.Object getCachedValue​(java.lang.Object key)
        Description copied from class: VmObjectLike
        Reads from the properties cache for this object. The cache contains the values of all members defined in this object or an ancestor thereof which have been requested with this object as the receiver.
        Specified by:
        getCachedValue in class VmObjectLike

      • setCachedValue

        public void setCachedValue​(java.lang.Object key,
                           java.lang.Object value)
        Description copied from class: VmObjectLike
        Writes to the properties cache for this object. The cache contains the values of all members defined in this object or an ancestor thereof which have been requested with this object as the receiver.
        Specified by:
        setCachedValue in class VmObjectLike

      • iterateMemberValues

        public boolean iterateMemberValues​(VmObjectLike.MemberValueConsumer consumer)
        Description copied from class: VmObjectLike
        Iterates over member definitions and their values in order of their definition, from the top of the prototype chain downwards. If a member value has not yet been evaluated, a `null` `value` is passed to `consumer`. If a member is defined in multiple objects in the prototype chain, i.e., is overridden along the way, it is visited only once, with the initial (i.e., upmost) `member` and the final (i.e., downmost) `value`. (This peculiar behavior serves two purposes in the current implementation: it guarantees that a `hidden` property is still recognized as such when overridden, and that an element is still recognized as such when overridden with entry syntax. It also means that members are visited in order of (first) definition.) Local, hidden, and external properties are not visited. If an invocation of `consumer` returns `false`, the remaining members are not visited, and `false` is returned. Otherwise, all members are visited, and `true` is returned.
        Specified by:
        iterateMemberValues in class VmObjectLike

      • iterateMembers

        public boolean iterateMembers​(java.util.function.BiFunction<java.lang.Object,​ObjectMember,​java.lang.Boolean> consumer)
        Description copied from class: VmObjectLike
        Iterates over member definitions in order of their definition, from the top of the prototype chain downwards. If a member is defined multiple times, each occurrence is visited. Local properties are not visited. If an invocation of `consumer` returns `false`, the remaining members are not visited, and `false` is returned. Otherwise, all members are visited, and `true` is returned.
        Specified by:
        iterateMembers in class VmObjectLike
