abs_rc_range_t

Defined in header: <ixion/address.hpp>

struct abs_rc_range_t

Stores absolute range address, but unlike the abs_range_t counterpart, this struct only stores row and column positions. The “rc” in the name stands for row and column.

Public Types

enum init_invalid

Tag type for constructing an invalid range.

Values:

enumerator invalid

Public Functions

abs_rc_range_t()

Construct a range covering the top-left cell.

abs_rc_range_t(init_invalid)

Construct an invalid range, with both positions invalid.

abs_rc_range_t(const abs_rc_range_t &other)

Copy constructor.

explicit abs_rc_range_t(const abs_range_t &other)

Construct a range from a range with a sheet, dropping the sheet.

abs_rc_range_t(row_t _row, col_t _col, row_t _row_span, col_t _col_span)

Construct a range from its top-left cell and its size.

Parameters:

• _row – 0-based row position of the top-left cell of the range.

• _col – 0-based column position of the top-left cell of the range.

• _row_span – Row length of the range. It must be 1 or greater.

• _col_span – Column length of the range. It must be 1 or greater.

bool valid() const

Check whether the range is valid, that is, both positions are valid and the first position does not follow the last one in any direction.

void set_all_columns()

Expand the range horizontally to include all columns. The row range will remain unchanged.

void set_all_rows()

Expand the range vertically to include all rows. The column range will remain unchanged.

bool all_columns() const

Returns:

true if the range is unspecified in the horizontal direction i.e. all columns are selected, false otherwise.

bool all_rows() const

Returns:

true if the range is unspecified in the vertical direction i.e. all rows are selected, false otherwise.

bool contains(const abs_rc_address_t &addr) const

Check whether or not a given address is contained within this range.

std::strong_ordering operator<=>(const abs_rc_range_t &r) const

Order ranges by their first position, then their last position.

bool operator==(const abs_rc_range_t &r) const

Compare both positions of two ranges.

Public Members

abs_rc_address_t first

Position of the top-left cell of the range.

abs_rc_address_t last

Position of the bottom-right cell of the range.

struct hash

Hash function for use in unordered containers.

Public Functions

size_t operator()(const abs_rc_range_t &range) const

Compute the hash value of a range.
