Detailed Description

template<typename T>
class boost::attributes::counter< T >

A class of an attribute that counts an integral value.

This type of attribute acts as a counter, that is, it returns a monotonously changing value each time requested. The attribute value type can be specified as a template parameter. However, the type must be an integral type of size no more than sizeof(long).

Member Typedef Documentation

template<typename T >

typedef T boost::attributes::counter< T >::value_type

A counter value type.

Constructor & Destructor Documentation

template<typename T >

boost::attributes::counter< T >::counter ( value_type  initial = (value_type)0, long  step = 1  )

inlineexplicit

Constructor.

Parameters

initial	Initial value of the counter
step	Changing step of the counter. Each value acquired from the attribute will be greater than the previous one to this amount.

References boost::attribute::set_impl().

template<typename T >

boost::attributes::counter< T >::counter ( cast_source const &  source )

inlineexplicit

Constructor for casting support.
