An interface reference expression, that is, the name of an interface, optionally qualified by a qualifier (separated from it by a member operator ‘.’), or empty for the current interface, prefixed by the type keyword interface and surrounded by backticks.

The qualifier may only be null if the name is also null. If the name exists, the qualifier must exist as well (but may of course be empty).

Examples:

`interface Iterable`
`interface A.B.C`
`interface`

no subtypes hierarchy

Initializer
InterfaceDec(UIdentifier? name, DecQualifier? qualifier = ...)
Parameters:
  • name

    The name of the declaration, or null for a reference to the current type (only in a ClassDec or InterfaceDec).

  • qualifier = DecQualifier()

    The qualifier of the dec, if present.

Attributes
childrenshared actual <DecQualifier|Identifier>[] children

The child nodes of this node.

Refines Expression.children ultimately refines Node.children
hashshared actual Integer hash

The hash value of the value, which allows the value to be an element of a hash-based set or key of a hash-based map. Implementations must respect the constraint that:

  • if x==y then x.hash==y.hash.

Therefore, a class which refines equals must also refine hash.

Because the Integer type is platform-dependent a compiler for a given platform is permitted to further manipulate the calculated hash for an object, and the resulting hash may differ between platforms.

Refines Object.hash
keywordshared actual String keyword

The keyword of the declaration literal, that is:

Refines Dec.keyword
nameshared actual UIdentifier? name

The name of the declaration, or null for a reference to the current type (only in a ClassDec or InterfaceDec).

Refines TypeDec.name
qualifiershared actual DecQualifier? qualifier

The qualifier of the dec, if present.

Methods
copyshared InterfaceDec copy(UIdentifier? name = ..., DecQualifier? qualifier = ...)
Parameters:
  • name = this.name
  • qualifier = this.qualifier
equalsshared actual Boolean equals(Object that)

Determine if two values are equal. Implementations should respect the constraints that:

  • if x===y then x==y (reflexivity),
  • if x==y then y==x (symmetry),
  • if x==y and y==z then x==z (transitivity).

Furthermore it is recommended that implementations ensure that if x==y then x and y have the same concrete class.

A class which explicitly refines equals() is said to support value equality, and the equality operator == is considered much more meaningful for such classes than for a class which simply inherits the default implementation of identity equality from Identifiable.

Refines Object.equals
transformshared actual Result transform<out Result>(Transformer<Result> transformer)

Transform this node with the given transformer by calling the appropriate transformX method on the transformer.

If you have a Node node that’s actually an LIdentifier instance, then the runtime will call LIdentifier.transform; therefore, this method is by nature narrowing. This means that if transformer is a NarrowingTransformer, calling node.transform(transformer) is equivalent to calling transformer.transformNode(node). On the other hand, if transformer is a WideningTransformer, then the two operations are very different.

visitshared actual void visit(Visitor visitor)

Visit this node with the given visitor. Calls the appropriate visitX method on the visitor.

Refines Node.visit
