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]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

static int vtkConditionVariable::IsTypeOf

(

const char *

name

)

[static]

Return 1 if this class type 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.

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]

Reimplemented from vtkObject.

virtual vtkObjectBase* vtkConditionVariable::NewInstanceInternal

(

)

const [protected, virtual]

Reimplemented from vtkObject.

vtkConditionVariable* vtkConditionVariable::NewInstance

(

)

const

Reimplemented from vtkObject.

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 180 of file vtkConditionVariable.h.

void vtkConditionVariable::Broadcast

(

)

[inline]

Wake all threads waiting for the condition to change.

Definition at line 185 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.
