Description

A queue class specialized for cPacket objects.

The added value is that this class keeps track of the total queue length in bits as well.

Constructor & Destructor Documentation

◆ cPacketQueue() [1/3]

cPacketQueue	(	const char *	name = `nullptr`,
		Comparator *	cmp = `nullptr`
	)

inline

Constructor. When comparator argument is nullptr, the queue will act as FIFO, otherwise as priority queue.

◆ cPacketQueue() [2/3]

cPacketQueue	(	const char *	name,
		CompareFunc	cmp
	)

inline

Constructor. Sets up cPacketQueue as a priority queue.

◆ cPacketQueue() [3/3]

cPacketQueue ( const cPacketQueue & queue )

Copy constructor. Contained objects that are owned by the queue will be duplicated so that the new queue will have its own copy of them.

Member Function Documentation

◆ operator=()

cPacketQueue& operator= ( const cPacketQueue & queue )

Assignment operator. Contained objects that are owned by the queue will be duplicated so that the new queue will have its own copy of them.

The name member is not copied; see cNamedObject::operator=() for details.

◆ dup()

virtual cPacketQueue* dup ( ) const

inlineoverridevirtual

Creates and returns an exact copy of this object. Contained objects that are owned by the queue will be duplicated so that the new queue will have its own copy of them.

Reimplemented from cQueue.

◆ str()

virtual std::string str ( ) const

overridevirtual

Produces a one-line description of the object's contents. See cObject for more details.

Reimplemented from cQueue.

◆ parsimPack()

virtual void parsimPack ( cCommBuffer * buffer ) const

overridevirtual

Serializes the object into an MPI send buffer. Used by the simulation kernel for parallel execution. See cObject for more details.

Reimplemented from cQueue.

◆ parsimUnpack()

virtual void parsimUnpack ( cCommBuffer * buffer )

overridevirtual

Deserializes the object from an MPI receive buffer Used by the simulation kernel for parallel execution. See cObject for more details.

Reimplemented from cQueue.

◆ insert()

virtual void insert ( cPacket * pkt )

virtual

Adds an element to the back of the queue. Trying to insert nullptr is an error (throws cRuntimeError). The given object must be an instance of cPacket.

◆ insertBefore()

virtual void insertBefore	(	cPacket *	where,
		cPacket *	pkt
	)

virtual

Inserts exactly before the given object. If the given position does not exist or if you try to insert nullptr, cRuntimeError is thrown. The given object must be an instance of cPacket.

◆ insertAfter()

virtual void insertAfter	(	cPacket *	where,
		cPacket *	pkt
	)

virtual

Inserts exactly after the given object. If the given position does not exist or if you try to insert nullptr, cRuntimeError is thrown. The given object must be an instance of cPacket.

◆ remove()

virtual cPacket* remove ( cPacket * pkt )

virtual

Unlinks and returns the object given. If the object is not in the queue, nullptr is returned. The given object must be an instance of cPacket.

◆ pop()

virtual cPacket* pop ( )

overridevirtual

Unlinks and returns the front element in the queue. If the queue is empty, cRuntimeError is thrown.

Reimplemented from cQueue.

◆ clear()

virtual void clear ( )

overridevirtual

Empties the container. Contained objects that were owned by the queue (see getTakeOwnership()) will be deleted.

Reimplemented from cQueue.

◆ getBitLength()

int64_t getBitLength ( ) const

inline

Returns the total size of the messages in the queue, in bits. This is the sum of the message bit lengths; see cPacket::getBitLength().

◆ getByteLength()

int64_t getByteLength ( ) const

inline

Returns the sum of the message lengths in bytes, that is, getBitLength()/8. If getBitLength() is not a multiple of 8, the result is rounded up.

◆ front()

virtual cPacket* front ( ) const

inlineoverridevirtual

Returns pointer to the object at the front of the queue. This is the element to be return by pop(). Returns nullptr if the queue is empty.

Reimplemented from cQueue.

References cQueue::front().

◆ back()

virtual cPacket* back ( ) const

inlineoverridevirtual

Returns pointer to the last (back) element in the queue. This is the element most recently added by insert(). Returns nullptr if the queue is empty.

Reimplemented from cQueue.

References cQueue::back().

◆ get()

virtual cPacket* get ( int i ) const

inlineoverridevirtual

Returns the ith element in the queue, or nullptr if i is out of range. get(0) returns the front element. This method performs linear search.

Reimplemented from cQueue.

References cQueue::get().
