Detailed Description

Iterate over the mutex meta data.

Constructor & Destructor Documentation

MutexMonitor()

MutexMonitor::MutexMonitor ( )

default

Constructor.

~MutexMonitor()

MutexMonitor::~MutexMonitor ( )

default

Destructor.

Member Function Documentation

disable()

void MutexMonitor::disable

(

)

Disable the mutex monitoring.

Note: We don't add any latch meta-data after startup. Therefore there is no need to use a mutex here.

enable()

void MutexMonitor::enable

(

)

Enable the mutex monitoring.

Note: We don't add any latch meta-data after startup. Therefore there is no need to use a mutex here.

iterate()

template<typename Callback >

bool MutexMonitor::iterate ( Callback &  callback ) const

inline

Invoke the callback for each active mutex collection.

Parameters

[in,out]

callback

Functor to call

Returns

false if callback returned false

reset()

void MutexMonitor::reset

(

void

)

Reset the mutex monitoring values.

Reset the mutex monitoring counters.

Note: We don't add any latch meta-data after startup. Therefore there is no need to use a mutex here.
