# TastyUniverse

###

#### abstract class TastyUniverse extends TastyCore with FlagOps with TypeOps with AnnotationOps with ContextOps with SymbolOps with NameOps with TreeOps

A facade to `scala.tools.nsc.symbtab.SymbolTable`, providing operations that map from the language of TASTy to the nsc compiler, e.g. to create trees, resolve types and symbols.
