Class FloatArrayDataRow

java.lang.Object
  com.rapidminer.example.table.DataRow
      com.rapidminer.example.table.FloatArrayDataRow

All Implemented Interfaces:

java.io.Serializable

public class FloatArrayDataRow
extends DataRow

Implementation of DataRow that is backed by a float array. Please note that for most applications the precision of floats should be high enough. The highest precision is provided by DoubleArrayDataRows but these need the double amount compared to these float representations which are therefore a good trade-off between precision and memory usage.
