Constructor Detail

DiscreteParameter

public DiscreteParameter()

constructor. Does nothing

DiscreteParameter

public DiscreteParameter(java.lang.String VariableName,
                         int InitialValue,
                         java.lang.String[] Values)

Constructor for a discrete variable.

Parameters:

VariableName - Name of the free parameter as specified in the command file

InitialValue - Index of initial value of free parameter

Values - Set of admissible values

Method Detail

clone

protected java.lang.Object clone()

Clone

Overrides:

clone in class java.lang.Object

getIndex

public final int getIndex()

Gets the index that points to the currently selected value.

Returns:

index that points to the currently selected value.

length

public final int length()

Gets the number of elements

Returns:

the number of elements

getValueString

public final java.lang.String getValueString()

Gets the string representation of the currently selected value.

Returns:

the string representation of the currently selected value.

getValueString

public final java.lang.String getValueString(int ind)

Gets the string representation of the element with index ind.

Parameters:

ind - index of the element

Returns:

the string representation of the element with index ind

getValueDouble

public final double getValueDouble()

Gets the double representation of the currently selected value.
If the variable represents discrete numerical values, then the double value of the currently selected value is returned.
If the variable represents different string values, then the currently selected index is returned.

Returns:

the double representation of the currently selected value.

getValueDouble

public final double getValueDouble(int ind)

Gets the double representation of the element with index ind.
If the variable represents discrete numerical values, then the double value of the currently selected value is returned.
If the variable represents different string values, then the argument ind is returned.

Parameters:

ind - index of the element

Returns:

the double representation of the element with index ind

getDiscreteType

public int getDiscreteType()

Gets the discrete discreteType, as specified in DiscreteParameter.

Returns:

discreteType
0: string
1: integer
2: double
