Constructor Detail

MapFieldComparator

public MapFieldComparator(String orderFields,
                          String orderSequence,
                          String orderOperation,
                          String orderOrder,
                          String orderFactor)

Parameters:

orderFields - a '/' separated list of orderFields.

MapFieldComparator

public MapFieldComparator(List orderFields,
                          String orderSequence,
                          String orderOperation,
                          String orderOrder,
                          String orderFactor)

Parameters:

orderFields - the sorted list of fields that control the ordening

orderSequence - one of "as-is" (default), "reverse"

orderOperation - one of "none" (default), "average", "linear-weighted-average", "exponential-weighted-average"

orderOrder - one of "increasing" (default), "decreasing"

orderFactor - the increment per field for "linear-weighted-average" (default 1: F1 + 2*F2 + 3*F3) the factor per field for "exponential-weighted-average" (default 2: F1 + 2*F2 + 4*F3)

Method Detail

getList

public static List getList(String orderFields)

Parameters:

orderFields - a '/' separated list of orderFields.

Returns:

a list of the order fields

compare

public int compare(Object one,
                   Object two)

Specified by:
