Sawyer::CommandLine::Sum< T > Class Template Reference


template<typename T>
class Sawyer::CommandLine::Sum< T >

Sums all previous and current values.

The template argument must match the type of the summed values.

This augmenter can be used for switches that increment a value, such as a debug switch where each occurrence of the switch increments a debug level:

int debugLevel = 0;
switchGroup.insert(Switch("debug", "d")
.intrinsicValue("1", integerParser(debugLevel))

Member Typedef Documentation

template<typename T >
typedef SharedPointer<Sum> Sawyer::CommandLine::Sum< T >::Ptr

Reference counting pointer for this class.

Definition at line 1847 of file CommandLine.h.

Constructor & Destructor Documentation

template<typename T >
Sawyer::CommandLine::Sum< T >::Sum ( )

Constructor for derived classes.

Non-subclass users should use instance instead.

Definition at line 1844 of file CommandLine.h.

Member Function Documentation

template<typename T >
static Ptr Sawyer::CommandLine::Sum< T >::instance ( )

Allocating constructor.

Returns a pointer to a new Sum object. Uses will most likely want to use the sum factory instead, which requires less typing.

Command line value augmenter factories, and the ValueAugmenter class.

template<typename T >
virtual ParsedValues Sawyer::CommandLine::Sum< T >::operator() ( const ParsedValues savedValues,
const ParsedValues newValues 

Called when a switch's value is about to be stored into the ParserResult.

The previously stored switch values for all switch occurrences that used this same key are provided in the first arugment. The recently parsed value (or values if the switch value was a list that was then exploded) is provided as the second argument. The function should return a new value (or values) that will replace the values passed on the command-line.

Implements Sawyer::CommandLine::ValueAugmenter.
