Detailed Description

A base class for all classes handling default parameters.

This class facilitates the handling of parameters:

it manages default parameter (defaults_)
it checks for valid parameters:
- unknown/misspelled parameter names
- correct parameter type

range restrictions of numeric parameters

valid values for string parameters (enum)

subsections that are passed to other classes can be excluded from the check (subsections_)

it keeps member variables in synchronicity with the parameters stored in param_
it helps to automatically create a doxygen documentation page for the parameters

Extra member variables are needed if getting the value from param_ would be too slow e.g. when they are used in methods that are called very often.

No matter if you have extra variables or not, do the following:

Set defaults_ and subsections_ in the derived classes' default constructor.
Make sure to set the 'advanced' flag of the parameters right in order to hide certain parameters from inexperienced users.
Set the range restrictions for numeric defaults and valid strings for string defaults (if possible)
Call defaultsToParam_() at the end of derived classes' default constructor. It copies the defaults to param_ (and calls updateMembers_()).

If you have extra member variables you need to synchronize with param_, do the following:

Implement the updateMembers_() method. It is used after each change of param_ in order to update the extra member variables. If the base class is a DefaultParamHandler as well make sure to call the updateMembers_() method of the base class in the updateMembers_() method.
Call updateMembers_() at the end of the derived classes' copy constructor and assignment operator.
If you need mutable access to the extra member variables, provide a set-method and make sure to set the corresponding value in param_ as well!

Base classes:
If you create a class A that is derived from DefaultParamHandler and derive another class B for A, you should set use the setName(String) method to set the name used for error messages to B.

Parameter documentation:
Each default parameter has to be documented in a comprehensive way. This is done using the Param::setValue methods and the Param::setDescription method.

Flags:
Flags (boolean parameters) are not supported directly. It's best to implement them as a string parameter with valid strings 'true' and 'false'.

◆ setParameters()

void setParameters ( const Param & param )

Sets the parameters.

Before setting the parameters, missing parameters are filled up with default values.
Then the parameters are checked for unknown parameters (warning) and violations of restrictions (exception) with the Param::checkDefaults() method.

Exceptions

Exception::InvalidParameter is thrown if errors occur during the check.

Member Data Documentation

◆ check_defaults_

bool check_defaults_

protected

If this member is set to false no checking if parameters in done;.

The only reason to set this member to false is that the derived class has no parameters! However, if a grand-child has defaults and you are using a base class cast, checking will not be done when casting back to grand-child. To just omit the warning, use 'warn_empty_defaults_'

◆ defaults_

Param defaults_

protected

Container for default parameters. This member should be filled in the constructor of derived classes!

Note: call the defaultsToParam_() method at the end of the constructor in order to copy the defaults to param_.
