Method Details

createInstance

public MOPSOParameterSpace createInstance()

Description copied from class: ParameterSpace

Creates and configures a new instance of this parameter space.

This method is part of the prototype pattern, allowing parameter spaces to be cloned with the same configuration. Implementations should return a new instance of the concrete parameter space class with the same parameter configuration.

Example implementation:

 @Override
 public ParameterSpace createInstance() {
     return new MyParameterSpace();
 }
 

Specified by:

createInstance in class ParameterSpace

Returns:

a new instance of this parameter space

setParameterSpace

protected void setParameterSpace()

Initializes all parameters in the parameter space. This method is called by the ParameterSpace constructor.

setParameterRelationships

protected void setParameterRelationships()

Sets up relationships between parameters. This method is called by the ParameterSpace constructor.

setTopLevelParameters

protected void setTopLevelParameters()

Identifies and adds the top-level parameters to the list. This method is called by the ParameterSpace constructor.
