Method Detail

probability

public double probability(long outcome)

Description copied from class: AbstractDiscreteDistribution

Returns the probability of the specified outcome in this distribution. This abstract method is the only one that needs to be implemented by subclasses, though most will also override the minimum and maximum outcome methods.

Specified by:

probability in interface DiscreteDistribution

Specified by:

probability in class AbstractDiscreteDistribution

Parameters:

outcome - Outcome whose probability is returned.

Returns:

Probability of specified outcome.

minOutcome

public long minOutcome()

Description copied from class: AbstractDiscreteDistribution

Returns the minimum outcome with non-zero probability for this distribution. Implemented to return the constant Long.MIN_VALUE. If possible, concrete subclasses should override this method with a tighter bound.

Specified by:

minOutcome in interface DiscreteDistribution

Overrides:

minOutcome in class AbstractDiscreteDistribution

Returns:

The minimum outcome for this distribution.

maxOutcome

public long maxOutcome()

Description copied from class: AbstractDiscreteDistribution

Returns the maximum outcome with non-zero probability for this distribution. Implemented to return the constant Long.MAX_VALUE. If possible, concrete subclasses should override this method with a tighter bound.

Specified by:

maxOutcome in interface DiscreteDistribution

Overrides:

maxOutcome in class AbstractDiscreteDistribution

Returns:

The maximum outcome for this distribution.
