Constructor Detail

DiscreteVariable

public DiscreteVariable()

Default constructor for a DiscreteVariable.

DiscreteVariable

public DiscreteVariable(java.lang.String n_vb)

Simple constructor for DiscreteVariable.

Parameters:

n_vb - Name of the variable.

DiscreteVariable

public DiscreteVariable(java.lang.String vb,
                        int vi,
                        java.lang.String[] vl)

Simple constructor for DiscreteVariable.

Parameters:

vb - Name of the variable.

vi - Index of the variable.

vl - Values of the variable.

DiscreteVariable

public DiscreteVariable(DiscreteVariable dv)

Simple constructor for DiscreteVariable.

Parameters:

dv - DiscreteVariable that is copied into current DiscreteVariable.

Method Detail

index_of_value

public int index_of_value(java.lang.String value)

Determine the index of a value given its name; returns INVALID_INDEX if there is no index.

get_numeric_values

public DiscreteFunction get_numeric_values()

Produce an array of numeric values for the values of a variable. The values are direct translation of the string values into doubles; if the translation fails for a particular value, that value is replaced by its index.

print

public void print()

Print method for DiscreteVariable.

print

public void print(java.io.PrintStream out)

Print method for DiscreteVariable.

get_name

public java.lang.String get_name()

Get the name of the current DiscreteVariable.

set_name

public void set_name(java.lang.String n)

Set the name of the current DiscreteVariable.

get_index

public int get_index()

Get the index of the current DiscreteVariable.

number_values

public int number_values()

Return the number of values in the current DiscreteVariable.

get_values

public java.lang.String[] get_values()

Get the values of the current DiscreteVariable.

set_values

public void set_values(java.lang.String[] vals)

Set the values of the current DiscreteVariable.

get_value

public java.lang.String get_value(int i)

Get a value of the current DiscreteVariable.

Parameters:

i - Position of the value in the array of values.
