Detailed Description

A class representing a single program option.

The base class for a single program option. All options which hold values are derived from this class as the type of stored values may differ.

Most of the getter-methods throw exceptions because this base class is not meant to hold any values by itself. Instead, the derived classes implement the appropriate method (Option_Integer implements getInt, f.e.). So, when one tries to retrieve a value which is not of the type of the option, an exception will be thrown. This behaviour is meant to be valid, because errors like this one only occur when building and testing the application.

Due to described behaviour, this class has no public constructors. Only construction of derived, value and type holding, classes is allowed.

At the begin (after being constructed) an Option either has a default value or not. In dependence to this, myHaveTheDefaultValue is set. Also, myAmSet is set to true if a default value was supported. myAmWritable is set to true, indicating that a new value may be set.

Each option may have a description about its purpose stored. Furthermore, it stores a man-readable type name for this option.

◆ set()

virtual bool Option::set	(	const std::string &	v,

pure virtual

Stores the given value.

This method is overriden by all option classes. The value is converted into the proper type and stored in "myValue". Then, "markSet" is called in order to know that a value has been set.

The method returns whether the value could be set (the return value from "markSet").

If the string could not be converted into the type, an InvalidArgument is thrown.

Returns: Whether the new value could be set

Exceptions

InvalidArgument If the value could not be converted
