Detailed Description

Critical section locking class.

FastMutexLock allows the locking of variables which are accessed through different threads. This header file also defines SimpleFastMutexLock which is not a subclass of Object. The API is identical to that of MutexLock, and the behavior is identical as well, except on Windows 9x/NT platforms. The only difference on these platforms is that MutexLock is more flexible, in that it works across processes as well as across threads, but also costs more, in that it evokes a 600-cycle x86 ring transition. The FastMutexLock provides a higher-performance equivalent (on Windows) but won't work across processes. Since it is unclear how, in itk, an object at the itk level can be shared across processes in the first place, one should use FastMutexLock unless one has a very good reason to use MutexLock. If higher-performance equivalents for non-Windows platforms (Irix, SunOS, etc) are discovered, they should replace the implementations in this class

Member Function Documentation

virtual::itk::LightObject::Pointer itk::FastMutexLock::CreateAnother ( ) const
virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::Object.

virtual const char* itk::FastMutexLock::GetNameOfClass ( ) const
virtual

Run-time type information.

Reimplemented from itk::Object.

void itk::FastMutexLock::Lock ( )
inline

Lock the itkFastMutexLock.

virtual void itk::FastMutexLock::PrintSelf ( std::ostream &  os,
Indent  indent

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from itk::Object.

bool itk::FastMutexLock::TryLock ( )
inline

Non-blocking Lock access.

Returns
bool - true if lock is captured, false if it was already held by someone else.

Definition at line 102 of file itkFastMutexLock.h.

void itk::FastMutexLock::Unlock ( )
inline

Unlock the FastMutexLock.
