public double map(double value)

Description copied from class: Function

Map a value through the function.

Overrides:

map in class Function

getMinValue

public double getMinValue()

Return the largest possible function value. If no exact value can be produced easily, this should return an estimation (upper bound).

Specified by:

getMaxValue in class Function

Returns:

the maximum function result.

toXML

Description copied from class: Function

Adds a function element to XML.

Specified by:

toXML in interface Storable

Overrides:

toXML in class Function

Parameters:

element - the parent element

Returns:

the function element

fromXML

Description copied from interface: Storable

Reads attributes from XML tree.

Specified by:

fromXML in interface Storable

Overrides:

fromXML in class Function

Parameters:

element - a JDOM element
