Class CachedTriple<T1,T2,T3>

java.lang.Object

org.tribuo.util.infotheory.impl.CachedTriple<T1,T2,T3>

Type Parameters:

T1 - The type of the first object.

T2 - The type of the second object.

T3 - The type of the third object.

All Implemented Interfaces:

Serializable

public class CachedTriple<T1,T2,T3>
extends Object
implements Serializable

A triple of things. The inner pairs are cached, as is the hashcode.

The cache is calculated on construction, and the objects inside the triple are thus expected to be immutable. If they aren't then the behaviour is undefined (and you shouldn't use this class).

Method Detail

getA

public T1 getA()

getB

public T2 getB()

getC

public T3 getC()

getAB

public CachedPair<T1,T2> getAB()

getAC

public CachedPair<T1,T3> getAC()

getBC

hashCode

public int hashCode()

Overrides:

hashCode in class Object

calculateHashCode

public int calculateHashCode()

Overridden hashcode. Checks to see if the types are ints or longs, and runs them through the mixing function if they are. Then XORs the two hashcodes together.

Returns:

A 32-bit integer.

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
