Public Types
typedef std::map< uintptr_t, SerializableObject *, std::less< uintptr_t > >	forwardType
	Type of the forward map.
typedef std::map< SerializableObject *, uintptr_t, std::less< SerializableObject * > >	reverseType
	Type of the reverse map.

Public Member Functions
forwardType::const_iterator	begin ()
	Get an iterator to the start of the forward map.
forwardType::const_iterator	end ()
	Get an iterator to the end of the forward map.
uintptr_t	emplace (SerializableObject *p)
	Store a new object in the table.
void	emplace (uintptr_t id, SerializableObject *p)
	Store a new object in the table using a specific ID.
bool	HasID (SerializableObject *p)
	Checks if we have an object at a specific pointer.
bool	HasID (uintptr_t id)
	Checks if we have an object with a specific ID.
void	ReserveID (uintptr_t id)
	Marks an ID as unavailable for use, without assigning an pointer to it.
template<class T >
T *	Lookup (uintptr_t id)
	Type-safe object lookup.
uintptr_t	operator[] (SerializableObject *key)
	Forward lookup.
void	clear ()
	Deletes all entries from the table.
void	erase (uintptr_t key)
	Erase an entry given a forward key.
void	erase (SerializableObject *key)
	Erase an entry given a reverse key.
void	replace (SerializableObject *oldval, SerializableObject *newval)
	Replaces one value with another, keeping the keys identical.
size_t	size () const
	Return the number of entries in the bijection.

Protected Attributes
uintptr_t	m_nextID
	Index of the next ID to be assigned.
forwardType	m_forwardMap
	Map of object-to-object in the forward direction.
reverseType	m_reverseMap
	Map of object-to-object in the reverse direction.

Detailed Description

Bidirectional table mapping integer IDs in scopesession files to object pointers.

Pointers must be SerializableObject derived to ensure type safety

Member Function Documentation

emplace() [1/2]

uintptr_t IDTable::emplace ( SerializableObject *  p )

inline

Store a new object in the table.

Parameters

p	Pointer to the object

Returns

The ID of the object

emplace() [2/2]

void IDTable::emplace ( uintptr_t  id, SerializableObject *  p  )

inline

Store a new object in the table using a specific ID.

Parameters

id	ID to assign to the object
p	Pointer to the object

erase() [1/2]

void IDTable::erase ( SerializableObject *  key )

inline

Erase an entry given a reverse key.

Parameters

key	The object to remove

erase() [2/2]

void IDTable::erase ( uintptr_t  key )

inline

Erase an entry given a forward key.

Parameters

key	The object to remove

HasID() [1/2]

bool IDTable::HasID ( SerializableObject *  p )

inline

Checks if we have an object at a specific pointer.

Parameters

p	Pointer to the object

HasID() [2/2]

bool IDTable::HasID ( uintptr_t  id )

inline

Checks if we have an object with a specific ID.

Parameters

id	ID of the object
