Detailed Description

template<class T>
class wex::statistics< T >

Offers base statistics.

All statistics involve a key value pair, where the key is a string, and the value a template. There are some virtual methods you can use in a base class e.g. to show the statistics on a grid, that is automatically updated whenever statistics change.

Constructor & Destructor Documentation

statistics()

template<class T >

wex::statistics< T >::statistics ( const std::vector< std::pair< const std::string, T > > & v = {} )

inlineexplicit

Default constructor.

You can specify a vector of values to initialize the statistics.

Member Function Documentation

clear()

template<class T >

virtual void wex::statistics< T >::clear ( )

inlinevirtual

Clears the items.

If you have shown the statistics the window is updated as well.

Reimplemented in wex::grid_statistics< T >.

get()

template<class T >

const std::string wex::statistics< T >::get ( ) const

inline

Returns all items as a string.

All items are returned as a string, with comma's separating items, and a : separating key and value.

set()

template<class T >

virtual const T wex::statistics< T >::set ( const std::string & key, T value )

inlinevirtual

Sets key to value.

If you have shown the statistics the window is updated as well.

Reimplemented in wex::grid_statistics< T >.
