Definition at line 26 of file EventSlot.h.

27 : algsStates( numberOfAlgorithms, MS ), controlFlowState( numberOfControlFlowNodes, -1 ){};

◆ EventSlot() [2/4]

EventSlot::EventSlot ( const EventSlot & )

delete

Copy constructor.

◆ EventSlot() [3/4]

EventSlot::EventSlot ( EventSlot && )

default

Move constructor.

◆ EventSlot() [4/4]

EventSlot::EventSlot	(	EventSlot &	original,
		std::unique_ptr< EventContext >	theeventContext,
		const std::string &	nodeName
	)

inline

Member Function Documentation

◆ addSubSlot()

void EventSlot::addSubSlot	(	std::unique_ptr< EventContext >	viewContext,
		const std::string &	nodeName
	)

inline

Add a subslot to the slot (this constructs a new slot and registers it with the parent one)

Definition at line 61 of file EventSlot.h.

                                                                                         {
     unsigned int lastIndex = allSubSlots.size();
  
     auto search = subSlotsByNode.find( nodeName );
     if ( search != subSlotsByNode.end() )
       subSlotsByNode[nodeName].push_back( lastIndex );
     else
       subSlotsByNode.emplace( std::piecewise_construct, std::forward_as_tuple( nodeName ),
                               std::forward_as_tuple( 1, lastIndex ) );
  
     // Make new slot and nest it into the top slot
     viewContext->setSubSlot( lastIndex );
     allSubSlots.emplace_back( *this, std::move( viewContext ), nodeName );
   }

◆ disableSubSlots()

void EventSlot::disableSubSlots ( const std::string & nodeName )

inline

Disable event views for a given CF view node by registering an empty container Contact B.

                                                     {
     subSlotsByNode.emplace( std::piecewise_construct, std::forward_as_tuple( nodeName ), std::forward_as_tuple() );
   }

◆ operator=() [1/2]

EventSlot& EventSlot::operator= ( const EventSlot & )

delete

Assignment operator.

◆ operator=() [2/2]

EventSlot& EventSlot::operator= ( EventSlot && )

default

Move assignment.

◆ reset()

void EventSlot::reset ( EventContext * theeventContext )

inline

Reset all resources in order to reuse the slot (thread-unsafe)

Definition at line 49 of file EventSlot.h.

                                               {
     eventContext.reset( theeventContext );
     algsStates.reset();
     controlFlowState.assign( controlFlowState.size(), -1 );
     complete = false;
     entryPoint.clear();
     parentSlot = nullptr;
     subSlotsByNode.clear();
     allSubSlots.clear();
   };
