ScalaPrimitives

abstract class ScalaPrimitives extends AnyRef

Scala primitive operations are represented as methods in Any and AnyVal subclasses. Here we demultiplex them by providing a mapping from their symbols to integers. Different methods exist for different value types, but with the same meaning (like plus, minus, etc.). They will all be mapped to the same int.

Note: The three equal methods have the following semantics:

  • "==" checks for null, and if non-null, calls java.lang.Object.equals (class: Any; modifier: final). Primitive: EQ
  • "eq" usual reference comparison (class: AnyRef; modifier: final). Primitive: ID
  • "equals" user-defined equality (Java semantics) (class: Object; modifier: none). Primitive: EQUALS

Inspired from the scalac compiler.
