A character literal consists of a single character or an escape sequence.

Note: in contrast to IntegerLiteral and FloatLiteral, the value of text isn’t verified, and there is no attribute to get the Character value of the literal; getting that value requires unicode support (to parse \{CHARACTER NAME}) that isn’t available on all platforms.

CharacterLiteral(String text)
  • text

    The text of the character literal (without quotes), i. e. either a single character or an escape sequence.

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
textSource Codeshared actual String text

The text of the character literal (without quotes), i. e. either a single character or an escape sequence.

copySource Codeshared CharacterLiteral copy(String text = ...)
  • text = this.text
equalsSource Codeshared actual Boolean equals(Object other)

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.
