Detailed Description

\inmodule QtCore

The QCollatorSortKey class can be used to speed up string collation.

Since

5.2

The QCollatorSortKey class is always created by QCollator::sortKey() and is used for fast strings collation, for example when collating many strings.

Member Function Documentation

compare()

int QCollatorSortKey::compare

(

const QCollatorSortKey &

otherKey

)

const

Compares this key to otherKey, which must have been created by the same QCollator's sortKey() as this key.

The comparison is performed in accordance with that QCollator's sort order.

Returns a negative value if this key sorts before otherKey, 0 if the two keys are equal or a positive value if this key sorts after otherKey.
