Formula Name Resolver

class ixion::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(const char *p, size_t n, const abs_address_t &pos) const = 0
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
virtual std::string get_name(const table_t &table) const = 0
virtual std::string get_column_name(col_t col) const = 0

Given a numerical representation of column position, return its textural representation.

Return
textural representation of column position.
Parameters
  • col: numerical column position.

Public Static Functions

static std::unique_ptr<formula_name_resolver> get(formula_name_resolver_t type, const iface::formula_model_access *cxt)

Create a formula name resolver instance according to the requested type.

Return
formula name resolver instance created on the heap. The caller is responsible for managing its life cycle.
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.

struct ixion::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:

invalid = 0
cell_reference
range_reference
table_reference
named_expression
function

Public Functions

formula_name_t()
std::string to_string() const

Return a string that represents the data stored internally. Useful for debugging.
