Class defining a thread pool for building BVH for the list of Select3D_SensitiveEntity within background thread(s). More...
#include <SelectMgr_BVHThreadPool.hxx>
Data Structures | |
class | BVHThread |
Thread with back reference to thread pool and thread mutex in it. More... | |
class | Sentry |
Class providing a simple interface to mutexes for list of BVHThread. More... | |
Public Member Functions | |
SelectMgr_BVHThreadPool (Standard_Integer theNbThreads) | |
Main constructor. More... | |
virtual | ~SelectMgr_BVHThreadPool () |
Destructor. More... | |
void | AddEntity (const Handle< Select3D_SensitiveEntity > &theEntity) |
Queue a sensitive entity to build its BVH. More... | |
void | StopThreads () |
Stops threads. More... | |
void | WaitThreads () |
Waits for all threads finish their jobs. More... | |
NCollection_Array1< BVHThread > & | Threads () |
Returns array of threads. More... | |
Public Member Functions inherited from Standard_Transient | |
Standard_Transient () | |
Empty constructor. More... | |
Standard_Transient (const Standard_Transient &) | |
Copy constructor – does nothing. More... | |
Standard_Transient & | operator= (const Standard_Transient &) |
Assignment operator, needed to avoid copying reference counter. More... | |
virtual | ~Standard_Transient () |
Destructor must be virtual. More... | |
virtual void | Delete () const |
Memory deallocator for transient classes. More... | |
virtual const opencascade::handle< Standard_Type > & | DynamicType () const |
Returns a type descriptor about this object. More... | |
Standard_Boolean | IsInstance (const opencascade::handle< Standard_Type > &theType) const |
Returns a true value if this is an instance of Type. More... | |
Standard_Boolean | IsInstance (const Standard_CString theTypeName) const |
Returns a true value if this is an instance of TypeName. More... | |
Standard_Boolean | IsKind (const opencascade::handle< Standard_Type > &theType) const |
Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism. More... | |
Standard_Boolean | IsKind (const Standard_CString theTypeName) const |
Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism. More... | |
Standard_Transient * | This () const |
Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero. More... | |
Standard_Integer | GetRefCount () const |
Get the reference counter of this object. More... | |
void | IncrementRefCounter () const |
Increments the reference counter of this object. More... | |
Standard_Integer | DecrementRefCounter () const |
Decrements the reference counter of this object; returns the decremented value. More... | |

NCollection_List< Handle< Select3D_SensitiveEntity > > | myBVHToBuildList |
list of queued sensitive entities More... | |
NCollection_Array1< BVHThread > | myBVHThreads |

Standard_Boolean | myToStopBVHThread |
flag to stop BVH threads More... | |
Standard_Mutex | myBVHListMutex |
mutex for interaction with myBVHToBuildList More... | |
Standard_Condition | myWakeEvent |
raises when any sensitive is added to the BVH list More... | |
Standard_Condition | myIdleEvent |
raises when BVH list become empty More... | |
Standard_Boolean | myIsStarted |
indicates that threads are running More... | |
