A well-typed and terminating term. Once you add a new Term, you should:

  • Method Details

    • descent

      @NotNull @NotNull Term descent(@NotNull @NotNull UnaryOperator<Term> f, @NotNull @NotNull UnaryOperator<Pat> g)
      Descending an operation to the term AST. NOTE: Currently we require the operation `f` to preserve:
      invalid @link 
      StructCall
      , DataCall, SortTerm, Shaped.Applicable.

    • subst

      @NotNull default @NotNull Term subst(@NotNull @NotNull AnyVar var, @NotNull @NotNull Term term)

    • subst

      @NotNull default @NotNull Term subst(@NotNull @NotNull Subst subst)

    • subst

      @NotNull default @NotNull Term subst(@NotNull @NotNull kala.collection.Map<? extends AnyVar,? extends Term> subst)

    • subst

      @NotNull default @NotNull Term subst(@NotNull @NotNull Subst subst, int ulift)

    • rename

      @NotNull default @NotNull Term rename()

    • findUsages

    • normalize

      @NotNull default @NotNull Term normalize(@NotNull @NotNull TyckState state, @NotNull @NotNull NormalizeMode mode)
      Parameters:
      state - used for inlining the holes. Can be null only if we're absolutely sure that holes are frozen, like in the error messages.

    • freezeHoles

      @NotNull default @NotNull Term freezeHoles(@Nullable @Nullable TyckState state)

    • toDoc

      @NotNull default @NotNull org.aya.pretty.doc.Doc toDoc(@NotNull @NotNull org.aya.util.prettier.PrettierOptions options)
      Specified by:
      toDoc in interface AyaDocile

    • lift

      @NotNull default @NotNull Term lift(int ulift)

    • computeType

      @NotNull default @NotNull Term computeType(@NotNull @NotNull TyckState state, @NotNull @NotNull LocalCtx ctx)
      Returns:
      WHNF
      Throws:
      NullPointerException - if the term is an introduction rule
