Detailed Description

Local namespace for command line parser.

Function Documentation

std::ostream& JPARSER::getOstream ( )

inline

Get output stream for conversion to std::string.

Note that the stream is emptied before use.

Returns

output stream

Definition at line 70 of file JParser.hh.

  {
    static std::ostringstream buffer;

    buffer.str("");

    return buffer;
  }

bool JPARSER::fail ( std::istream &  in )

inline

Check for stream state.

Note that end-of-file is not defined as an error so to normally process e.g. std::string and std::vector.

Parameters

in	input stream

Returns

true if failure; else false

Definition at line 113 of file JParser.hh.

  {
    return in.bad() || (in.fail() && !in.eof());
  }

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

inline

Auxiliary method for creation of template parser element object.

Parameters

object	object
name	name of object
help	help of object

Returns

parser element

Definition at line 1899 of file JParser.hh.

  {
    return JParserTemplateElement<bool>(object, name, help);
  }

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

inline

Auxiliary method for creation of template parser element object.

Parameters

object	object
name	name of object
help	help of object

Returns

parser element

Definition at line 1913 of file JParser.hh.

  {
    return JParserTemplateElement<JCounter>(object, name, help);
  }

template<class JType_t >

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

inline

Auxiliary method for creation of template parser element object.

Parameters

object	object
name	name of object
help	help of object

Returns

parser element

Definition at line 1928 of file JParser.hh.

  {
    return JParserTemplateElement<JType_t>(object, name, help);

inline

Auxiliary method for creation of template parser element object.

Parameters

object	object
name	name of object
help	help of object
__begin	begin of possible values
__end	end of possible values

Returns

parser element

Definition at line 1945 of file JParser.hh.

  {
    return JParserTemplateElement<JType_t>(object, name, help, __begin, __end);
  }

template<class JType_t , class T >

JParserTemplateElement<JType_t> JPARSER::getOption ( JType_t &  object, const std::string &  name, T  __begin, T  __end  )

inline

Auxiliary method for creation of template parser element object.
