A class reference expression, that is, the name of a class or anonymous class, optionally qualified by a qualifier (separated from it by a member operator ‘.’), prefixed by the type keyword class and surrounded by backticks.

The name may be an LIdentifier to refer to the class declaration of an anonymous class. For example, in

value dec1 = `class null`;
value dec2 = `value null`;

dec1 refers to the anonymous class of the null object, while dec2 refers to the only instance of that class, the null object itself.

Examples:

`class String`
`class A.B.C`

no subtypes hierarchy

Initializer
ClassDec(Identifier name, DecQualifier? qualifier = null)
Parameters:
  • name

    The name of the declaration.

  • qualifier = null

    The qualifier of the dec, if present.

Attributes
childrenSource Codeshared actual <DecQualifier|Identifier>[] children

The child nodes of this node.

Refines Expression.children ultimately refines Node.children
hashSource Codeshared 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.

Refines Object.hash
keywordSource Codeshared actual String keyword

The keyword of the declaration literal, that is:

Refines Dec.keyword
nameSource Codeshared actual Identifier name

The name of the declaration.

Refines TypeDec.name
qualifierSource Codeshared actual DecQualifier? qualifier

The qualifier of the dec, if present.

Methods
copySource Codeshared ClassDec copy(Identifier name = ..., DecQualifier? qualifier = ...)
Parameters:
  • name = this.name
  • qualifier = this.qualifier
equalsSource Codeshared 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.

transformSource Codeshared 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.
