A comma-separated list of import elements, where the last element may optionally be a wildcard instead, surrounded by braces.

Import elements may not be empty.

(ceylon.ast ImportElements are slightly different from the specification’s ImportElements; in the specification, the surrounding braces are always part of the “parent” node (Import, ImportTypeElement), while in ceylon.ast, they are part of the ImportElements.)

Examples:

MutableList, ArrayList
JString=String, System { sysout=out }

no subtypes hierarchy

Initializer
ImportElements(ImportElement[] elements = [], ImportWildcard? wildcard = null)
Parameters:
  • elements = []

    The regular import elements.

  • wildcard = null

    The import wildcard, if present.

Attributes
childrenSource Codeshared actual [<ImportElement|ImportWildcard>+] children

The child nodes of this node.

elementsSource Codeshared ImportElement[] elements

The regular import elements.

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
wildcardSource Codeshared ImportWildcard? wildcard

The import wildcard, if present.

Methods
copySource Codeshared ImportElements copy(ImportElement[] elements = ..., ImportWildcard? wildcard = ...)
Parameters:
  • elements = this.elements
  • wildcard = this.wildcard
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.
