Detailed Description

Packet factory.

Allows allocating packets and packet buffers (byte buffers of appropriate size that should be attached to packet to hold payload).

Serves several purposes:

• implements convenient and type-safe wrapper on top of memory pools
• combines two related pools (packet pool and buffer pool) in one class
• detaches pipeline logic from memory management interface, so that it can change independently without affecting every pipeline element

Constructor & Destructor Documentation

PacketFactory() [1/2]

roc::packet::PacketFactory::PacketFactory	(	core::IArena &	arena,
		size_t	buffer_size
	)

Initialize with default pools. buffer_size defines number of bytes in packet buffer.

PacketFactory() [2/2]

roc::packet::PacketFactory::PacketFactory	(	core::IPool &	packet_pool,
		core::IPool &	buffer_pool
	)

Initialize with custom pools. packet_pool is a pool of packet::Packet objects. buffer_pool is a pool of core::Buffer objects.
