interpolationSearch

public static int interpolationSearch(List<? extends DatabaseRowWithLongPrimaryKey> inList,
                                      Long inTargetRowId)

Searches a List of DatabaseRowWithLongPrimaryKey objects sorted in ascending order to find the matching row with the specified id. Slower than a HashMap approach but more memory efficient. More performant when used with ArrayLists than with LinkedLists.

Parameters:

inList - the sorted List to be searched

inTargetRowId - the row id to be searched for

Returns:

the index of the row with the matching rowId or -1 if it is not present in the list
