An invocation, that is, an invoked expression with an argument list.

Examples:

print("Hello, World!")
process.kill()
ArrayList { initialCapacity = 100; 1, 1 }

no subtypes hierarchy

Initializer
Invocation(Primary invoked, Arguments arguments = ...)
Parameters:
  • invoked

    The invoked expression.

  • arguments = PositionalArguments()

    The arguments.

Attributes
argumentsSource Codeshared Arguments arguments

The arguments.

childrenSource Codeshared actual [Primary, Arguments] 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
invokedSource Codeshared Primary invoked

The invoked expression.

Methods
copySource Codeshared Invocation copy(Primary invoked = ..., Arguments arguments = ...)
Parameters:
  • invoked = this.invoked
  • arguments = this.arguments
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.
