ProbabilisticInteger

public ProbabilisticInteger()

Method Detail

updateValue

public java.lang.Integer updateValue()

Description copied from class: Vertex

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

Specified by:

updateValue in class Vertex<java.lang.Integer>

Returns:

The updated value

lazyEval

public java.lang.Integer lazyEval()

Description copied from class: Vertex

This causes a backwards propagating calculation of the vertex value. This propagation only happens for vertices with values dependent on parent values i.e. non-probabilistic vertices.

Specified by:

lazyEval in class Vertex<java.lang.Integer>

Returns:

The value at this vertex after recalculating any parent non-probabilistic vertices.

isProbabilistic

public boolean isProbabilistic()

Description copied from class: Vertex

A probabilistic vertex is defined as a vertex that is probabilistic.

Specified by:

isProbabilistic in class Vertex<java.lang.Integer>
