Method Detail

add

public void add(DiscreteVariable[] pvs)

Add an array of DiscreteVariable objects to the BayesNet.

add

public void add(DiscreteFunction[] pfs)

Add an array of DiscreteFunction objects to the BayesNet.

get_function

public DiscreteFunction get_function(DiscreteVariable p_v)

public int index_of_variable(java.lang.String n_vb)

Determine the position of a variable given its name.

get_name

public java.lang.String get_name()

Get the name of the network.

set_name

public void set_name(java.lang.String n)

Set the name of the network.

number_variables

public int number_variables()
