An import of another module within a module descriptor.

Each module import consists of a list of annotations, followed by the keyword ‘package’, the name of the imported module, and the version of the imported module, terminated by a semicolon.

Examples:

shared import ceylon.test "1.2.0";
import ceylon.collection "1.2.0";

no subtypes hierarchy

Initializer
ModuleImport(FullPackageName|StringLiteral name, StringLiteral version, Annotations annotations = ...)
Parameters:
  • name

    The name of the imported module.

    (For proper Ceylon modules, this should be a FullPackageName; string literals are allowed for interoperation with legacy Java code.)

  • version

    The version of the imported module.

  • annotations = Annotations()

    The annotations on the module import.

Attributes
annotationsshared Annotations annotations

The annotations on the module import.

childrenshared actual [Annotations, FullPackageName|StringLiteral, StringLiteral] 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|StringLiteral name

The name of the imported module.

(For proper Ceylon modules, this should be a FullPackageName; string literals are allowed for interoperation with legacy Java code.)

versionshared StringLiteral version

The version of the imported module.

Methods
copyshared ModuleImport copy(FullPackageName|StringLiteral name = ..., StringLiteral version = ..., Annotations annotations = ...)
Parameters:
  • name = this.name
  • version = this.version
  • 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.
