Method Detail

updateValue

public T updateValue()

Description copied from class: Vertex

This causes a non-probabilistic vertex to recalculate it's value based off it's parent's current values.

Specified by:

updateValue in class Vertex<T>

Returns:

The updated value

isProbabilistic

public boolean isProbabilistic()

Specified by:

isProbabilistic in class Vertex<T>

Returns:

True if the vertex is probabilistic, false otherwise. A probabilistic vertex is defined as a vertex whose value is not derived from it's parents. However, the probability of the vertex's value may be dependent on it's parents values.
