A module descriptor: a list of annotations, followed by the keyword ‘module’, and then the module name, version and body.

Examples (multi-line):

module tmp "1.0.0" {}

Initializer
ModuleDescriptor(FullPackageName name, StringLiteral version, ModuleBody body = ..., Annotations annotations = ...)
Parameters:
  • name

    The module name.

  • version

    The module version.

    (No constraints on the version – allowed characters, length, etc. – are specified, but some versions crash the compiler, and constraints will likely be specified at some point.)

  • body = ModuleBody()

    The module body.

  • annotations = Annotations()

    The module’s annotations. The most commonly used are:

    • documentation
    • license
    • by
Attributes
annotationsshared Annotations annotations

The module’s annotations. The most commonly used are:

  • documentation
  • license
  • by
bodyshared ModuleBody body

The module body.

childrenshared actual [Annotations, FullPackageName, StringLiteral, ModuleBody] children

The child nodes of this node.

hashshared 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.

Because the Integer type is platform-dependent a compiler for a given platform is permitted to further manipulate the calculated hash for an object, and the resulting hash may differ between platforms.

Refines Object.hash
nameshared FullPackageName name

The module name.

versionshared StringLiteral version

The module version.

(No constraints on the version – allowed characters, length, etc. – are specified, but some versions crash the compiler, and constraints will likely be specified at some point.)

Methods
copyshared ModuleDescriptor copy(FullPackageName name = ..., StringLiteral version = ..., ModuleBody body = ..., Annotations annotations = ...)
Parameters:
  • name = this.name
  • version = this.version
  • body = this.body
  • annotations = this.annotations
equalsshared 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.

Refines Object.equals
transformshared 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.

visitshared actual void visit(Visitor visitor)

Visit this node with the given visitor. Calls the appropriate visitX method on the visitor.
