Classes
class	regina::Packet
	Represents a packet of information that may be individually edited or operated upon. More...
class	regina::Packet::ChangeEventSpan
	An object that facilitates firing packetToBeChanged() and packetWasChanged() events. More...
class	regina::PacketOf< Held >
	A packet that stores a mathematical object of type Held. More...
class	regina::PacketData< Held >
	A lightweight helper class that allows an object of type Held to connect with the wrapped packet class that contains it. More...
class	regina::PacketData< Held >::ChangeEventSpan
	An object that facilitates firing packetToBeChanged() and packetWasChanged() events. More...
class	regina::ChildIterator< const_ >
	A forward iterator for iterating through all immediate children of a given packet. More...
class	regina::SubtreeIterator< const_ >
	A forward iterator for iterating through the entire packet subtree rooted at a given packet. More...
class	regina::PacketChildren< const_ >
	A lightweight object that gives access to all immediate children of a given packet. More...
class	regina::PacketDescendants< const_ >
	A lightweight object that gives access to all strict descendants of a given packet. More...
class	regina::PacketShell
	Gives access to the final remains of a packet that is in the process of being destroyed. More...
class	regina::PacketListener
	An object that can be registered to listen for packet events. More...

Namespaces
namespace	regina
	Contains the entire Regina calculation engine.

Macros
#define	REGINA_PACKET(id, name)
	Defines various constants and virtual functions for a subclass of Packet. More...

Enumerations
enum	regina::PacketHeldBy { regina::HELD_BY_NONE = 0 , regina::HELD_BY_PACKET = 1 , regina::HELD_BY_SNAPPEA = 2 }
	Internal constants that support wrapped packets. More...

Functions
template<typename Held >
std::shared_ptr< PacketOf< Held > >	regina::make_packet (Held &&src)
	Converts a temporary Held object into a new wrapped packet, without making a deep copy. More...
template<typename Held >
std::shared_ptr< PacketOf< Held > >	regina::make_packet (Held &&src, const std::string &label)
	Converts a temporary Held object into a new wrapped packet, without making a deep copy. More...
template<typename Held , typename... Args>
std::shared_ptr< PacketOf< Held > >	regina::make_packet (std::in_place_t, Args &&... args)
	Creates a new packet that wraps a Held object, passing the given arguments to the Held constructor. More...
template<typename Held >
std::shared_ptr< PacketOf< Held > >	regina::make_packet ()
	Creates a new packet that wraps a default-constructed Held object. More...
template<typename Held >
Held &	regina::static_packet_cast (Packet &p)
	Casts a reference from Packet to Held, assuming that the given packet is actually a PacketOf<Held>. More...
template<typename Held >
const Held &	regina::static_packet_cast (const Packet &p)
	Casts a const reference from Packet to Held, assuming that the given packet is actually a PacketOf<Held>. More...
std::shared_ptr< Packet >	regina::open (const char *filename)
	Reads a Regina data file, and returns the corresponding packet tree. More...
std::shared_ptr< Packet >	regina::open (std::istream &in)
	Reads a Regina data file from the given input stream, and returns the corresponding packet tree. More...
bool	regina::operator== (const Packet *packet, PacketShell shell)
	Identifies if the given shell refers to the given packet. More...
bool	regina::operator!= (const Packet *packet, PacketShell shell)
	Identifies if the given shell does not refer to the given packet. More...
