TypeAnalysis

class TypeAnalysis extends DepthFirstAstVisitor[Unit] with Analysis[TypeData]

Unification-based type analysis. The analysis associates a tip.types.Type with each variable declaration and expression node in the AST. It is implemented using tip.solvers.UnionFindSolver.

To novice Scala programmers: The parameter declData is declared as "implicit", which means that invocations of TypeAnalysis obtain its value implicitly: The call to new TypeAnalysis in Tip.scala does not explicitly provide this parameter, but it is in scope of implicit val declData: TypeData = new DeclarationAnalysis(programNode).analyze(). The TIP implementation uses implicit parameters many places to provide easy access to the declaration information produced by DeclarationAnalysis and the type information produced by TypeAnalysis. For more information about implicit parameters in Scala, see https://docs.scala-lang.org/tour/implicit-parameters.html.
