Class ArbitraryTokenDomain

java.lang.Object

aima.core.probability.domain.AbstractFiniteDomain

aima.core.probability.domain.ArbitraryTokenDomain

All Implemented Interfaces:

DiscreteDomain, Domain, FiniteDomain

public class ArbitraryTokenDomain
extends AbstractFiniteDomain

Artificial Intelligence A Modern Approach (3rd Edition): page 486. As in CSPs, domains can be sets of arbitrary tokens; we might choose the domain of Age to be {juvenile,teen,adult} and the domain of Weather might be {sunny,rain,cloudy,snow}.

Method Detail

size

public int size()

Specified by:

size in interface Domain

Specified by:

size in class AbstractFiniteDomain

Returns:

the size of the Domain, only applicable if isFinite() == true.

isOrdered

public boolean isOrdered()

Specified by:

isOrdered in interface Domain

Specified by:

isOrdered in class AbstractFiniteDomain

Returns:

true if the domain is ordered, false otherwise. i.e. you can specify 1 object from the domain is < or = another object in the domain.

getPossibleValues

public java.util.Set<java.lang.Object> getPossibleValues()

Specified by:

getPossibleValues in interface FiniteDomain

Specified by:

getPossibleValues in class AbstractFiniteDomain

Returns:

a consistent ordered Set (e.g. LinkedHashSet) of the possible values this domain can take on.

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object
