Detailed Description

template<>
class JPARSER::JParserTemplateElement< bool >

Template specialisation of JPARSER::JParserTemplateElement for type bool.

The value is by default set to false and set to true in method read() without reading any data. This makes it possible to parse mutiple options in one go (e.g. -abc). This class implements the JPARSER::JParserElementInterface interface.

Constructor & Destructor Documentation

JPARSER::JParserTemplateElement< bool >::JParserTemplateElement ( bool &  object, const std::string &  name = "arg", const std::string &  help = ""  )

inline

Constructor.

The constructor assigns the default value false to the referenced parameter.

Parameters

object	reference to object
name	name of object
help	help of object
