An object argument definition.

Examples (multi-line):

object destroyable satisfies Destroyable {
    shared actual void destroy(Anything error) => process.exit(1);
}

object items satisfies Iterable<Integer> {
    variable Integer accesses = 0;
    shared actual Iterator<Integer> iterator() => (0..(++accesses)).iterator();
}

Initializer
ObjectArgument(LIdentifier name, ClassBody body, ExtendedType? extendedType = null, SatisfiedTypes? satisfiedTypes = null)
Parameters:
  • name

    The name of the object, as well as of the parameter it’s assigned to.

  • body

    The body of the associated anonymous class.

  • extendedType = null

    The extended type of the associated anonymous class, if present.

  • satisfiedTypes = null

    The satisfied types of the associated anonymous class, if present.

Attributes
bodySource Codeshared ClassBody body

The body of the associated anonymous class.

childrenSource Codeshared actual <LIdentifier|ExtendedType|SatisfiedTypes|ClassBody>[] children

The child nodes of this node.

Refines ExpressionIsh.children ultimately refines Node.children
extendedTypeSource Codeshared ExtendedType? extendedType

The extended type of the associated anonymous class, if present.

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 actual LIdentifier name

The name of the object, as well as of the parameter it’s assigned to.

satisfiedTypesSource Codeshared SatisfiedTypes? satisfiedTypes

The satisfied types of the associated anonymous class, if present.

Methods
copySource Codeshared ObjectArgument copy(LIdentifier name = ..., ClassBody body = ..., ExtendedType? extendedType = ..., SatisfiedTypes? satisfiedTypes = ...)
Parameters:
  • name = this.name
  • body = this.body
  • extendedType = this.extendedType
  • satisfiedTypes = this.satisfiedTypes
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.
