Method CreateExpression

eval/public/cel_expression.h:107–112

Creates CelExpression object from a checked expression. This includes an AST, source info, type hints and ident hints. Method implementation is expected to create copy of checked_expr, so that the returned CelExpression is not dependent on the lifetime of the input arguments.

  // so that the returned CelExpression is not dependent on the lifetime of
  // the input arguments.
  virtual absl::StatusOr<std::unique_ptr<CelExpression>> CreateExpression(
      const cel::expr::CheckedExpr* checked_expr) const {
    // Default implementation just passes through the expr and source info.
    return CreateExpression(&checked_expr->expr(),
                            &checked_expr->source_info());
  }
