An integer literal may be expressed in decimal (no prefix), hexadecimal (prefix ‘#’) or binary (prefix ‘$’) notation. Integer literals may be grouped with underscores, and may contain a magnitude.

Initializer
IntegerLiteral(String text)
Parameters:
  • text

    The text of the literal, including prefixes, magnitude, etc.

Attributes
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.

In general, hash values vary between platforms and between executions of the same program.

Note that when executing on a Java Virtual Machine, the 64-bit Integer value returned by an implementation of hash is truncated to a 32-bit integer value by taking the exclusive disjunction of the 32 lowest-order bits with the 32 highest-order bits, before returning the value to the caller.

textshared actual String text

The text of the literal, including prefixes, magnitude, etc.

Methods
copyshared IntegerLiteral copy(String text = ...)
Parameters:
  • text = text = t
equalsshared actual Boolean equals(Object that)

Integer literals are considered equal iff their texts are equal. Two literals with the same integer values but different representations (grouping, magnitude, leading zeroes, and/or radix differ) are considered different.

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.
