Member Function Documentation

coefficient()

double EntryKeyDataDouble::coefficient ( const EntryKeyData *  data1, const EntryKeyData *  data2  ) const

virtual

Returns the relative position between two doubles.

Returns the double's relative position to the first double compared to the second. For example, if this double is 14, the first double is 10 and the second 20, relative position would be 0.4.

Parameters

data1	First double.
data2	Second double.

Returns

The relative position between two doubles.

Exceptions

WrongSubclass

Given data type was illegal.
