Detailed Description

RAII manager object for accessing paralle tick functionality.

This class works similarly to the scoped lock classes that most mutexes use.

This class is used to change the state of the global mutex and guarantee that it is reset to the original value regardless of how the code exits the block where the critical section is defined.

For examples of usage see the parallelTick example.

Constructor & Destructor Documentation

DtCriticalSection::DtCriticalSection ( DtSimManager *  , AccessType  initState  )

explicit

Construct and set mutex state to initial state.

DtCriticalSection::DtCriticalSection ( DtSimManager *  )

explicit

Construct and do not change mutex state.

DtCriticalSection::DtCriticalSection ( DtCriticalSection &  , AccessType  to  )

explicit

Construct when there is already another critical section object on the stack.

Note: other constructors will work here but this one may be more efficient.
