Detailed Description

template<class T, class Mutex>
class perfc::Locked< T, Mutex >

Simple type that provide synchronized access by holding a lock to T container.

Accessing the locked object is peformed using pointer semantics.

Constructor & Destructor Documentation

Locked() [1/2]

template<class T, class Mutex>

perfc::Locked< T, Mutex >::Locked ( ReferenceType t, Mutex & mutex )

inline

Construct by providing reference to object requiring synchronized access and the mutex protecting it.

Parameters

t	Object to obtain exclusive access to.
mutex	Mutex protecting t.

Exceptions

Exception

originating from Mutex::lock() (typically std::system_error)

Definition at line 71 of file register.hpp.

Locked() [2/2]

template<class T, class Mutex>

perfc::Locked< T, Mutex >::Locked ( Locked< T, Mutex > && other )

inlinenoexcept

Move constructs by taking owneship of internal state of other.

Parameters

other

Object to move from.

Definition at line 78 of file register.hpp.

Member Function Documentation

Get()

template<class T, class Mutex>

PointerType perfc::Locked< T, Mutex >::Get ( ) const

inlinenoexcept

Returns

Reference to underlying object.

Definition at line 99 of file register.hpp.

operator bool()

template<class T, class Mutex>

perfc::Locked< T, Mutex >::operator bool ( ) const

inlinenoexcept

Returns

true if to underlying object is valid, false otherwise.

Definition at line 118 of file register.hpp.

operator*()

template<class T, class Mutex>

ReferenceType perfc::Locked< T, Mutex >::operator* ( ) const

inlinenoexcept

Returns

Reference to underlying object.

Definition at line 105 of file register.hpp.

operator->()

template<class T, class Mutex>

PointerType perfc::Locked< T, Mutex >::operator-> ( ) const

inlinenoexcept

Returns

Pointer to underlying object.

Definition at line 111 of file register.hpp.

operator=()

template<class T, class Mutex>

Locked & perfc::Locked< T, Mutex >::operator= ( Locked< T, Mutex > && other )

inlinenoexcept

Move constructs by taking owneship of internal state of other.

Parameters

other

Object to move from.

Definition at line 88 of file register.hpp.

Unlock()

template<class T, class Mutex>

void perfc::Locked< T, Mutex >::Unlock ( )

inlinenoexcept

Note

There is no way to re-acquire lock after this.

Postcondition

Get() == nullptr
