Public Member Functions
	BSONInputArchive (std::istream &stream)
	Construct a BSONInputArchive from an input stream of BSON data. More...

bool	willSearchYieldValue ()
	Checks if the next invocation of search() will yield a value. More...

bool	startRootElementIfRoot ()
	Pushes a root element on the node stack if we're in root. More...

void	finishRootElementIfRootElement ()
	Pops the node stack and iterates to the next BSON view if the top of the stack specifies that we are in a root element.

void	startNode ()
	Starts a new node, and update the stacks so that we fetch the correct data when calling search().

void	finishNode ()
	Finishes the most recently started node by popping relevant stacks and, if necessary, iterating to the next root BSON document.

void	setNextName (const char *name)
	Sets the name for the next node created with startNode. More...

void	loadValue (std::chrono::system_clock::time_point &val)
	Loads a BSON datetime from the current node and puts it into a std::chrono::system_clock::time_point. More...

void	loadValue (std::string &val)
	Loads a BSON UTF-8 value from the current node and puts it into a std::string. More...

void	loadSize (cereal::size_type &size)
	Loads the size for a SizeTag, which is used by Cereal to determine how many elements to put into a container such as a std::vector. More...

void	loadUnderlyingDataForCurrentNode (UnderlyingBSONDataBase &underlyingData)
	Returns a shared pointer to the underlying data of the current node, loading the size in bytes in a size_t reference argument.

Constructor & Destructor Documentation

boson::BSONInputArchive::BSONInputArchive ( std::istream & stream )

inline

Construct a BSONInputArchive from an input stream of BSON data.

Parameters

stream The stream from which to read BSON data.

Member Function Documentation

void boson::BSONInputArchive::loadSize ( cereal::size_type & size )

inline

Loads the size for a SizeTag, which is used by Cereal to determine how many elements to put into a container such as a std::vector.

Parameters

size	A reference to the size value that will be set to the size of the array at the top of the stack.

void boson::BSONInputArchive::loadValue ( std::chrono::system_clock::time_point & val )

inline

Loads a BSON datetime from the current node and puts it into a std::chrono::system_clock::time_point.

Parameters

val	The time_point variable into which the datetime will be loaded.

void boson::BSONInputArchive::loadValue ( std::string & val )

inline

Loads a BSON UTF-8 value from the current node and puts it into a std::string.

Parameters

val	The std::string variable into which the UTF-8 will be loaded.

void boson::BSONInputArchive::setNextName ( const char * name )

inline

Sets the name for the next node created with startNode.

Parameters

name	The name of the next node

bool boson::BSONInputArchive::startRootElementIfRoot ( )

inline

Pushes a root element on the node stack if we're in root.

bool boson::BSONInputArchive::willSearchYieldValue ( )

inline

Checks if the next invocation of search() will yield a value.

Used to check if a particular optional element, embedded document, or embedded array exists.

If search() would indeed return a value, it is cached here so that the logic in search() will not need to be repeated.

Returns: true if the next invocation of search with the current _nextName yields a value, false otherwise.
