示例1:
// Stream output operator; prints in the following format:
// "(Priority tag) [Duedate Text] {Tag_1 / Tag_2 / Tag_3}
// ex: "(A) [4/17] write essay #3 {history, computer}
std::ostream& operator << (std::ostream& out, const Todo& aTodo)
{
char myPriority = aTodo.GetPriority();
Date myDueDate = aTodo.GetDate();
string todoText = aTodo.GetText();
vector<Tag> tagList = aTodo.GetTags();
// If the todo has a priority print it
if (myPriority != NULL)
{
// If priority is A, B, C, or D print colors for added emphasis
switch (myPriority)
{
case 'A':
aTodo.SetColor(Todo::YELLOW);
out << "(" << myPriority << ") ";
break;
case 'B':
aTodo.SetColor(Todo::GREEN);
out << "(" << myPriority << ") ";
break;
case 'C':
aTodo.SetColor(Todo::RED);
out << "(" << myPriority << ") ";
break;
case 'D':
aTodo.SetColor(Todo::TEAL);
out << "(" << myPriority << ") ";
break;
}
}
// If the todo has a due date print it
if ( !myDueDate.IsEmpty() )
out << myDueDate << " ";
out << todoText << " ";
// Print tags by traversing vector of tags, as long as there are tags available to print
if ( !tagList.empty() )
{
int pos = 0;
out << "{";
for (; pos < int(tagList.size()-1); pos++ )
out << tagList[pos] << ", ";
out << tagList[pos] << "}";
}
aTodo.SetColor(Todo::GRAY); // reset output color
return out;
}
