BoolProxyVertex(int[] shape, VertexLabel label)
BoolProxyVertex(VertexLabel label) This vertex acts as a "Proxy" to allow a BayesNet to be built up before parents are explicitly known (ie for model in model scenarios) but allows linking at a later point in time.

Constructor Detail

BoolProxyVertex

public BoolProxyVertex(VertexLabel label)

This vertex acts as a "Proxy" to allow a BayesNet to be built up before parents are explicitly known (ie for model in model scenarios) but allows linking at a later point in time.

Parameters:

label - The label for this Vertex (all Proxy Vertices must be labelled)

BoolProxyVertex

public BoolProxyVertex(int[] shape,
                       VertexLabel label)

Method Detail

calculate

public BooleanTensor calculate()

Specified by:

calculate in interface NonProbabilistic<BooleanTensor>

sample

public BooleanTensor sample(KeanuRandom random)

Specified by:

sample in class Vertex<BooleanTensor>

Parameters:

random - source of randomness

Returns:

a sample from the vertex's distribution. For non-probabilistic vertices, this will always be the same value.

setParent

public void setParent(BoolVertex newParent)

Specified by:

setParent in interface ProxyVertex<BoolVertex>

getParent

public BoolVertex getParent()

hasParent

public boolean hasParent()

Specified by:

hasParent in interface ProxyVertex<BoolVertex>
