A class instantiation, used in an extends clause and in a class alias.

(This node is only used as child of ExtendedType and ClassSpecifier; for normal instantiations of a class, use a regular Invocation with a BaseExpression for the class name.)

The class name may optionally be qualified with super..


super.Entry<Key, Item>(key, item)

ClassInstantiation(TypeNameWithTypeArguments name, PositionalArguments arguments, Super? qualifier = null)
  • name

    The type name (and type arguments) of the instantiated class.

  • arguments

    The arguments to the instantiation.

  • qualifier = null

    The super qualifier of the instantiation, if present.

argumentsSource Codeshared PositionalArguments arguments

The arguments to the instantiation.

childrenSource Codeshared actual Node[] children

The child nodes of this node.

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
nameSource Codeshared TypeNameWithTypeArguments name

The type name (and type arguments) of the instantiated class.

qualifierSource Codeshared Super? qualifier

The super qualifier of the instantiation, if present.

Inherited Attributes

copySource Codeshared ClassInstantiation copy(TypeNameWithTypeArguments name = ..., PositionalArguments arguments = ..., Super? qualifier = ...)
  • name = this.name
  • arguments = this.arguments
  • 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.
