contains

public boolean contains(K key)

Description copied from interface: Object2LongFrequencyDistribution

Returns true if key exists in this object.

Specified by:

contains in interface Object2LongFrequencyDistribution<K extends Comparable<K>>

get

public long get(K key)

Description copied from interface: Object2LongFrequencyDistribution

Returns the count of a particular event key.

Specified by:

get in interface Object2LongFrequencyDistribution<K extends Comparable<K>>

computeRelativeFrequency

public double computeRelativeFrequency(K k)

Description copied from interface: Object2LongFrequencyDistribution

Computes the relative frequency of a particular event key. That is, f(key) / SUM_i f(key_i).

Specified by:

computeRelativeFrequency in interface Object2LongFrequencyDistribution<K extends Comparable<K>>

computeLogRelativeFrequency

public double computeLogRelativeFrequency(K k)
