bool ScQueryCellIterator::FindEqualOrSortedLastInRange	(	SCCOL &	nFoundCol,
		SCROW &	nFoundRow
	)

In a range assumed to be sorted find either the last of a sequence of equal entries or the last being less than (or greater than) the queried value.

Used by the interpreter for [HV]?LOOKUP() and MATCH(). Column and row position of the found entry are returned, otherwise invalid.

The search does not stop when encountering a string and does not assume that no values follow anymore. If querying for a string a mismatch on the first entry, e.g. column header, is ignored.

! StopOnMismatch, TestEqualCondition and the internal IgnoreMismatchOnLeadingStrings and query params are in an undefined state upon return! The iterator is not usable anymore except for obtaining the number format!

void ScQueryCellIterator::SetStopOnMismatch ( bool bVal )

inline

If set, iterator stops on first non-matching cell content.

May be used in SC_LESS_EQUAL queries where a cell range is assumed to be sorted; stops on first value being greater than the queried value and GetFirst()/GetNext() return NULL. StoppedOnMismatch() returns true then. However, the iterator's conditions are not set to end all queries, GetCol() and GetRow() return values for the non-matching cell, further GetNext() calls may be executed.
