Member Function Documentation

allocate()

template<typename T >

optional<value_type> MQTT_NS::value_allocator< T >::allocate ( )

inline

Allocate one value.

Returns

If allocator has at least one value, then returns lowest value, otherwise return nullopt.

clear()

template<typename T >

void MQTT_NS::value_allocator< T >::clear ( )

inline

Clear all allocated or used values.

deallocate()

template<typename T >

void MQTT_NS::value_allocator< T >::deallocate ( value_type  value )

inline

Dellocate one value.

Parameters

value

value to deallocate. The value must be gotten by allocate() or declared by use().

dump()

template<typename T >

std::ostream& MQTT_NS::value_allocator< T >::dump ( std::ostream &  o )

inline

first_vacant()

template<typename T >

optional<value_type> MQTT_NS::value_allocator< T >::first_vacant ( ) const

inline

Get the first vacant value.

Returns

If allocator has at least one vacant value, then returns lowest value, otherwise return nullopt.

interval_count()

template<typename T >

std::size_t MQTT_NS::value_allocator< T >::interval_count ( ) const

inline

use()

template<typename T >

bool MQTT_NS::value_allocator< T >::use ( value_type  value )

inline

Declare the value as used.

Parameters

value

The value to declare using

Returns

If value is not used or allocated then true, otherwise false
