MessageSerivce Class Reference

Detailed Description

HyperPlot, Author: Sam Harnew, sam.h.nosp@m.arne.nosp@m.w@gma.nosp@m.il.c.nosp@m.om , Date: Dec 2015

This is used to print all of the output from HyperPlot to a chosen output stream (by default std::cout). Access to this class is done through the precompiler definitions.

WELCOME_LOG - A welcome message in the constructor of each class ERROR_LOG - Use to print error messages to the screen INFO_LOG - Use to print useful information to the screen VERBOSE_LOG - Use for verbose information GOODBYE_LOG - A goodbye message in the destructor of each class

ERROR_COUNT - Print out how many error messages have been shown. This is useful to call at the end of the main function

Member Function Documentation

MessageSerivce & MessageSerivce::getMessageService ( ErrorType  errorType )

static

Static function to retrive the MessageSerivce singleton. At the same time, also change the state of the MessageSerivce.

Definition at line 8 of file MessageService.cpp.

MessageSerivce & MessageSerivce::getMessageService ( )

static

Static function to retrive the MessageSerivce singleton without altering its message state

Definition at line 40 of file MessageService.cpp.

template<class T >

MessageSerivce& MessageSerivce::operator<< ( const T &  v )

inline

This makes is possible the do messageSerivce <<

Definition at line 83 of file MessageService.h.

MessageSerivce& MessageSerivce::operator<< ( StandardEndLine  manip )

inline

define an operator<< to take in std::endl

Definition at line 139 of file MessageService.h.

void MessageSerivce::printErrorCount

(

)

print how many errors messages have been sent to the output stream

Definition at line 77 of file MessageService.cpp.

Member Data Documentation

bool MessageSerivce::_endlCalled

bool was the last command sent to the steam a std::cout ?

Definition at line 61 of file MessageService.h.

long int MessageSerivce::_errorCount

Count the number of errors that happened.

Definition at line 74 of file MessageService.h.

ErrorType MessageSerivce::_errorType

The current message type of the MessageSerivce

Definition at line 70 of file MessageService.h.

std::map<ErrorType, TString> MessageSerivce::_outputHeaders

this is the string that proceeds each of the message types

Definition at line 57 of file MessageService.h.

std::map<ErrorType, bool> MessageSerivce::_outputOptions

this map decides what message types should be printed to the output stream (verbose, welcome and goodbye are off by default)

Definition at line 53 of file MessageService.h.

bool MessageSerivce::_printOrNot

For the current message type, should I be printing to the stream (means you don't have to use the map many times in a row i.e. faster)
