Enclosing interface:

TransitionModel

public static interface TransitionModel.Transition
extends java.lang.Comparable

Represents (information about) a transition option during a transition model.

An option is at least a 1-tuple <p> in [0,1] of the probability of reaching a state s' (in the corresponding context, i.e. from a state s in S with an action a in A(s)). However, it may contain any additional information about the transition.

Method Summary

int	compareTo(java.lang.Object o) Compares transition options.
boolean	equals(java.lang.Object o) Checks for equality.
Scalar	getProbability() Get the transition probability.
int	hashCode()

Method Detail

equals

boolean equals(java.lang.Object o)

Checks for equality.

Overrides:

equals in class java.lang.Object

hashCode

int hashCode()

Overrides:

hashCode in class java.lang.Object

compareTo

int compareTo(java.lang.Object o)

Compares transition options. In nondeterministic cases, implementations will usually compare transition options according to their probabilities. Deterministic cases, however, may prefer comparisons involving cost or accumulated cost. Those comparisons can also be combined. In any case, implementations are not required to use any specific order.

Specified by:

compareTo in interface java.lang.Comparable

getProbability

Scalar getProbability()

Get the transition probability.

Returns:

the transition probability p in [0,1] of taking this transition.
