An argument list.

A list of expressions, here called listed arguments, optionally followed by a spread argument or a comprehension.

ArgumentList(Expression[] listedArguments = [], SpreadArgument|Comprehension? sequenceArgument = null)
  • listedArguments = []

    The regular, listed arguments.

  • sequenceArgument = null

    The optional trailing spread argument or comprehension.

childrenSource Codeshared actual <Expression|SpreadArgument|Comprehension>[] children

The child nodes of this node.

Refines ExpressionIsh.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
listedArgumentsSource Codeshared Expression[] listedArguments

The regular, listed arguments.

sequenceArgumentSource Codeshared SpreadArgument|Comprehension? sequenceArgument

The optional trailing spread argument or comprehension.

Inherited Attributes

copySource Codeshared ArgumentList copy(Expression[] listedArguments = ..., SpreadArgument|Comprehension? sequenceArgument = ...)
  • listedArguments = this.listedArguments
  • sequenceArgument = this.sequenceArgument
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.
