Query Language Features

  • Model: Relational vs Tree
  • variable binding (unification) & back-reference
  • set operators
  • support for dataflow (Read/write references...)
  • aggregates (grouping results)
  • List pattern matching (i.e JTL style for argument list)
  • behavioural pattern matching (SOUL like, Jackpot)
  • quantifiers (forall, exists, no)
  • querying style: logic, query-by-example, path, sql

...

  • control flow statements
  • type information of AST nodes
  • type constraints (subtype relations)
  • generics / wildcards
  • anonymous class
