Member Function Documentation

coefficient()

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

virtual

Returns the relative position between two integers.

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

Parameters

data1	First integer.
data2	Second integer.

Returns

The relative position between two integers.

Exceptions

WrongSubclass

Given data type was illegal.
