Enum CompareFunctionType

java.lang.Object
  java.lang.Enum<CompareFunctionType>
      org.android.activityminer.pmml.model.CompareFunctionType

All Implemented Interfaces:

Serializable, Comparable<CompareFunctionType>

public enum CompareFunctionType
extends Enum<CompareFunctionType>

The compare function types for fields

Enum Constant Summary

absDiff
absolute difference: c(x,y) = |x-y|

delta
c(x,y) = 0 if x=y, 1 else

equal
c(x,y) = 1 if x=y, 0 else

gaussSim
gaussian similarity: c(x,y) = exp(-ln(2)*z*z/(s*s)) where z=x-y, and s is the value of attribute similarityScale (required in this case) in the ClusteringField

similarity
similarity measure type

table
c(x,y) = lookup in similarity matrix

Method Summary

static CompareFunctionType	valueOf(String name) Returns the enum constant of this type with the specified name.
static CompareFunctionType[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Method Detail

values

public static CompareFunctionType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (CompareFunctionType c : CompareFunctionType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static CompareFunctionType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
