    • size

      public int size()
      Description copied from interface: BasicProverEnvironment
      Get the number of backtracking points/levels on the current stack.

      Caution: This is the number of PUSH-operations, and not necessarily equal to the number of asserted formulas. On any level there can be an arbitrary number of asserted formulas. Even with size of 0, formulas can already be asserted (at bottom level).

      Specified by:
      size in interface BasicProverEnvironment<T>

    • push

      public final void push() throws InterruptedException
      Description copied from interface: BasicProverEnvironment
      Create a new backtracking point, i.e., a new level on the assertion stack. Each level can hold several asserted formulas.

      If formulas are added before creating the first backtracking point, they can not be removed via a POP-operation.

      Specified by:
      push in interface BasicProverEnvironment<T>
      Throws:
      InterruptedException

    • pushImpl

      protected abstract void pushImpl() throws InterruptedException
      Throws:
      InterruptedException

    • pop

      public final void pop()
      Description copied from interface: BasicProverEnvironment
      Remove one backtracking point/level from the current stack. This removes the latest level including all of its formulas, i.e., all formulas that were added for this backtracking point.
      Specified by:
      pop in interface BasicProverEnvironment<T>

    • popImpl

      protected abstract void popImpl()

    • addConstraint

      @CanIgnoreReturnValue public final @Nullable T addConstraint(BooleanFormula constraint) throws InterruptedException
      Description copied from interface: BasicProverEnvironment
      Add a constraint to the latest backtracking point.
      Specified by:
      addConstraint in interface BasicProverEnvironment<T>
      Throws:
      InterruptedException

    • addConstraintImpl

      protected abstract @Nullable T addConstraintImpl(BooleanFormula constraint) throws InterruptedException
      Throws:
      InterruptedException

    • getAssertedFormulas

      protected ImmutableSet<BooleanFormula> getAssertedFormulas()

    • getAssertedConstraintIds

      protected ImmutableSet<T> getAssertedConstraintIds()

    • registerEvaluator

      protected <E extends Evaluator> E registerEvaluator(E pEvaluator)
      This method registers the Evaluator to be cleaned up before the next change on the prover stack.

    • unregisterEvaluator

      protected void unregisterEvaluator(Evaluator pEvaluator)

    • closeAllEvaluators

      protected void closeAllEvaluators()

    • close

      public void close()
      Description copied from interface: BasicProverEnvironment
      Closes the prover environment. The object should be discarded, and should not be used after closing. The first call of this method will close the prover instance, further calls are ignored.
      Specified by:
      close in interface AutoCloseable
      Specified by:
      close in interface BasicProverEnvironment<T>
