Method Detail

delete

public void delete()

toString

public java.lang.String toString()

Convert the function to a displayable string.

Overrides:

toString in class java.lang.Object

getDomain

public java.util.List<java.lang.Double> getDomain()

The domain of the function. 2 * m elements, where m is the number of inputs to the function.

Each successive pair of elements gives the minimum and maximum values for one of the inputs.

Input values to the function are clamped to these minimum and maximum values.

setDomain

public void setDomain(java.util.List<java.lang.Double> domain)

The domain of the function. 2 * m elements, where m is the number of inputs to the function.

Each successive pair of elements gives the minimum and maximum values for one of the inputs.

Input values to the function are clamped to these minimum and maximum values.

getRange

public java.util.List<java.lang.Double> getRange()

The range of the function. 2 * n elements, where n is the number of outputs from the function.

Each successive pair of elements gives the minimum and maximum values for one of the outputs.

Output values from the function are clamped to these minimum and maximum values.

setRange

public void setRange(java.util.List<java.lang.Double> range)

The range of the function. 2 * n elements, where n is the number of outputs from the function.

Each successive pair of elements gives the minimum and maximum values for one of the outputs.

Output values from the function are clamped to these minimum and maximum values.

getNInputs

public int getNInputs()

The number of inputs to the function.

getNOutputs

public int getNOutputs()

The number of outputs from the function.

apply

public java.util.List<java.lang.Double> apply(java.util.List<java.lang.Double> args)

Apply the function to supplied input values

Parameters:

args - input values for the function. The number of input values must agree with the number of inputs the function takes.

Returns:

a list of the result values from the function
