Example 37 with CharacterCodingException

use of java.nio.charset.CharacterCodingException in project mkgmap by openstreetmap.

the class Sort method createSortKey.

/**
 * Create a sort key for a given unicode string.  The sort key can be compared instead of the original strings
 * and will compare based on the sorting represented by this Sort class.
 *
 * Using a sort key is more efficient if many comparisons are being done (for example if you are sorting a
 * list of strings).
 *
 * @param object This is saved in the sort key for later retrieval and plays no part in the sorting.
 * @param s The string for which the sort key is to be created.
 * @param second Secondary sort key.
 * @param cache A cache for the created keys. This is for saving memory so it is essential that this
 * is managed by the caller.
 * @return A sort key.
