A scale expression.

Defined via Scalable.scale(). Right-associative.

Examples:

2 ** vector
brakeFactor ** velocity

The scale operation is special because the receiver of the method invocation by which it is defined is the right-hand side, not the left-hand side. In other words, lhs ** rhs corresponds to

rhs.scale(lhs)

while e. g. lhs * rhs corresponds to

lhs.times(rhs)

(the qualifier and argument swapped places).

Initializer
ScaleOperation(MultiplyingExpression factor, ScalingExpression scalable)
Parameters:
  • factor

    The factor by which the scalable is scaled

  • scalable

    The Scalable being scaled

Attributes
childrenSource Codeshared actual [MultiplyingExpression, ScalingExpression] children

The child nodes of this node.

Refines BinaryOperation.children ultimately refines Node.children
factorSource Codeshared MultiplyingExpression factor

The factor by which the scalable is scaled

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.

Methods
copySource Codeshared ScaleOperation copy(MultiplyingExpression leftOperand = ..., ScalingExpression rightOperand = ...)
Parameters:
  • leftOperand = this.leftOperand
  • rightOperand = this.rightOperand
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.
