Detailed Description

template<typename T>
class mir::Synchronised< T >

An object that enforces unique access to the data it contains.

This behaves like a mutex which owns the data it guards, and can give out a smart-pointer-esque handle to lock and access it.

Template Parameters

T	The type of data contained

Member Typedef Documentation

Locked

template<typename T >

using mir::Synchronised< T >::Locked = LockedImpl<T>

Smart-pointer-esque accessor for the protected data.

Ensures exclusive access to the referenced data.

Note

Instances of Locked must not outlive the Synchronised they are derived from.

LockedView

template<typename T >

using mir::Synchronised< T >::LockedView = LockedImpl<T const>

Smart-pointer-esque accessor for the protected data.

Provides const access to the protected data, with the guarantee that no changes to the data can be made while this handle is live.

Note

Instances of Locked must not outlive the Synchronised they are derived from.

Member Function Documentation

lock() [1/2]

template<typename T >

auto mir::Synchronised< T >::lock ( ) -> Locked

inline

Lock the data and return an accessor.

Returns

A smart-pointer-esque accessor for the contained data. While code has access to a live Locked instance it is guaranteed to have unique access to the contained data.

lock() [2/2]

template<typename T >

auto mir::Synchronised< T >::lock ( ) const -> LockedView

inline

Lock the data and return an accessor.

Returns

A smart-pointer-esque accessor for the contained data. While code has access to a live Locked instance it is guaranteed to have unique access to the contained data.
