Detailed Description

mutual exclusion locking class

vtkConditionVariable allows the locking of variables which are accessed through different threads. This header file also defines vtkSimpleConditionVariable which is not a subclass of vtkObject.

The win32 implementation is based on notes provided by Douglas C. Schmidt and Irfan Pyarali, Department of Computer Science, Washington University, St. Louis, Missouri. http://www.cs.wustl.edu/~schmidt/win32-cv-1.html

Member Function Documentation

static vtkConditionVariable* vtkConditionVariable::New ( )

static

static int vtkConditionVariable::IsTypeOf ( const char * type )

static

virtual int vtkConditionVariable::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

static vtkConditionVariable* vtkConditionVariable::SafeDownCast ( vtkObjectBase * o )

static

virtual vtkObjectBase* vtkConditionVariable::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkObject.

vtkConditionVariable* vtkConditionVariable::NewInstance ( ) const

void vtkConditionVariable::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

virtual

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 vtkObject.

void vtkConditionVariable::Signal ( )

inline

Wake one thread waiting for the condition to change.

Definition at line 184 of file vtkConditionVariable.h.

void vtkConditionVariable::Broadcast ( )

inline

Wake all threads waiting for the condition to change.

Definition at line 189 of file vtkConditionVariable.h.

int vtkConditionVariable::Wait ( vtkMutexLock * mutex )

inline

Wait for the condition to change. Upon entry, the mutex must be locked and the lock held by the calling thread. Upon exit, the mutex will be locked and held by the calling thread. Between entry and exit, the mutex will be unlocked and may be held by other threads.

Parameters

mutex The mutex that should be locked on entry and will be locked on exit (but not in between)

Return values

Normally,this function returns 0. Should a thread be interrupted by a signal, a non-zero value may be returned.
