Formula Name Resolver
-
class formula_name_resolver
Formula name resolvers resolves a name in a formula expression to a more concrete name type.
Public Functions
-
formula_name_resolver()
-
virtual ~formula_name_resolver() = 0
-
virtual formula_name_t resolve(std::string_view s, const abs_address_t &pos) const = 0
Parse and resolve a reference string.
- Parameters:
s – reference string to be parsed.
pos – base cell position, which influences the resolved reference position(s) containing relative address(es). When the reference string does not contain an explicit sheet name, the sheet address of the base cell position is used.
- Returns:
result of the resovled reference.
-
virtual std::string get_name(const address_t &addr, const abs_address_t &pos, bool sheet_name) const = 0
-
virtual std::string get_name(const range_t &range, const abs_address_t &pos, bool sheet_name) const = 0
Public Static Functions
-
static std::unique_ptr<formula_name_resolver> get(formula_name_resolver_t type, const model_context *cxt)
Create a formula name resolver instance according to the requested type.
- Parameters:
type – type formula name resolver being requested.
cxt – document model context for resolving sheet names, or nullptr in case names being resolved don’t contain sheet names.
- Returns:
formula name resolver instance created on the heap. The caller is responsible for managing its life cycle.

struct formula_name_t
Structure that represents the type of a ‘name’ in a formula expression.
A name can be either one of:
cell reference
range reference
table reference
named expression
function
Public Types
-
enum name_type
Values:
-
enumerator invalid
-
enumerator cell_reference
-
enumerator range_reference
-
enumerator table_reference
-
enumerator named_expression
-
enumerator function
-
enumerator invalid
-
using value_type = std::variant<address_t, range_t, table_type, formula_function_t>
Public Functions
-
formula_name_t()
-
std::string to_string() const
Return a string that represents the data stored internally. Useful for debugging.
-
struct table_type
Table information for a table reference name. Unlike the ixion::table_t counterpart, we store strings as string views as the resolver doesn’t have access to the string pool.
