Public Member Functions

 RampFunction ()
 Default constructor.
 
 RampFunction (double minX, double maxX, double minY=-1, double maxY=+1)
 Construct a linear updater.
 
virtual ~RampFunction ()
 Destructor.
 
virtual void apply (DoubleVector &inputs, DoubleVector &outputs)
 Implement the updating method.
 
virtual void configure (ConfigurationParameters &params, QString prefix)

Detailed Description

Ramp Function.

Warning
The old name (before version 1.1.0) of RampFunction was LinearFunction while now LinearFunction express a simple linear equation y=mx+b
   maxY            /---------------
                  /
                 /
                /
   minY -------/
            minX   maxX
  

Further Details coming soon ;-)

void apply ( DoubleVector inputs,
DoubleVector outputs 
)
virtual

Implement the updating method.

Implements OutputFunction.

void configure ( ConfigurationParameters params,
QString  prefix 
)
virtual

Configures the object using a ConfigurationParameters object.

Parameters
paramsthe configuration parameters object with parameters to use
prefixthe prefix to use to access the object configuration parameters. This is guaranteed to end with the separator character when called by the factory, so you don't need to add one

Save the actual status of parameters into the ConfigurationParameters object passed.

Parameters
paramsthe configuration parameters object on which save actual parameters
prefixthe prefix to use to access the object configuration parameters.
