Detailed Description

A thread monitor class.

A thread monitor, which collects information about the resources of all running threads.

To add a new thread to the monitor, the method addThisThread must be called within the created thread. To remove a thread, the method removeThisThread or removeThread should be called. If a thread is stopped without calling removeThisThread first, it will be automatically removed from the internal thread list when getThreadInformation() is called.

The method getThreadInformation returns a vector of all threads of the current process (not only the threads, which are added using addThisThread). For each thread, the creation time and the used CPU time in user mode and kernel mode are determined. For threads, which were added using addThisThread also the name is returned in the vector.

Example:

void processThread()
{
    ThreadMonitor::instance().addThisThread("MyThreadName");
    while (!boost::this_thread::interruption_requested())
    {
        ...
    }
    ThreadMonitor::instance().removeThisThread();
}

int main(int pArgc, char* pArgv[])
{
    ...
    boost::thread tMyThread(boost::bind(&processThread));
    ...
    ThreadMonitor::ThreadInfoVector tInfos =
        ThreadMonitor::instance().getThreadInformation();
}

Member Function Documentation

addThisThread()

void addThisThread

(

const std::string &

pName

)

Add the calling thread to the thread monitor.

Parameters

[in]

pName

The name of the thread.

removeThisThread()

void removeThisThread

(

)

Remove the calling thread from the monitor.

removeThread() [1/3]

void removeThread

(

const boost::thread &

pThread

)

Remove a thread from the monitor.

Parameters

[in]

pThread

The thread, which should be removed.

removeThread() [2/3]

void removeThread

(

const boost::thread::id &

pThreadID

)

Remove a thread from the monitor.

Parameters

[in]

pThreadID

The boost thread ID.

removeThread() [3/3]

void removeThread

(

ThreadID

pThreadID

)

Remove a thread from the monitor.

Parameters

[in]

pThreadID

The native thread ID.

getThreadInformation()

ThreadInfoVector getThreadInformation

(

)

Collect information about all threads of the current process.

Returns

The information vector (

See also

ThreadInfo and

ThreadInfoVector).

instance()

static Type& instance ( )

inlinestaticinherited

Returns a reference to the singleton instance.

Exceptions

XSingleton

If the singleton was already destroyed (dead reference) or not yet created (when using ExplicitInstantiation).

isDestroyed()

static bool isDestroyed ( )

inlinestaticinherited

Returns true, if the singleton was already destroyed.

Trying to access it will result in an exception.

makeInstance()

static Type* makeInstance ( )
