Public Member Functions
	Bundle ()
	create an empty bundle
	Bundle (const MetaData::Bundle &otherBundle)
	create a new bundle based upon other bundles. This performs a shallow copy.
void	operator= (const MetaData::Bundle &otherBundle)
	assign this bundle based upon another bundle. This performs a shallow copy.
bool	operator== (const MetaData::Bundle &otherBundle) const
	compare two bundles. Returns true if they are identical.
size_t	size () const
	how many metadata elements there are in this bundle
const_iterator	begin () const
	get iterator to the first piece of metadata
const_iterator	end () const
	get iterator pointing past the last piece of metadata
const_iterator	find (const char *key) const
	find a particular piece of metadata by key. returns end() if not present.
const_iterator	find (const std::string &key) const
	find a particular piece of metadata by key. returns end() if not present.
const_iterator	erase (const_iterator it)
const_iterator	erase (const char *key)
const_iterator	erase (const std::string &key)
const data_t &	meta () const
	return the underlying std::map for the metadata
PropertyPtr	getData (const char *key) const
	return the pointer to the named metadata element
PropertyPtr	getData (const std::string &key) const
	return the pointer to the named metadata element
double	getDouble (const char *key) const
	return the named metadata element as a double. this will convert strings to numbers. XXX: need to convert rationals as well.
unsigned char	getUnsignedChar (const char *key) const
	return the named metadata element as an unsigned int. this will convert strings to numbers. XXX: need to convert rationals as well.
std::string	getString (const char *key) const
	return the named metadata as a string. this involves converting ints and doubles to strings, and formatting arrays by inserting commas
void	setDataIfNotNan (const std::string &key, double number)
	set the given key to the given number, if and only if number is not NAN. A deep copy may be performed if necessary
void	setDataIfNotEmpty (const std::string &key, const std::string &data)
	set the given key to the given string, if and only if data is not empty. A deep copy may be performed if necessary
void	setData (const std::string &key, float data)
	set the given key to the given data. A deep copy may be performed if necessary
void	setData (const std::string &key, const float *data, unsigned count)
	set the given key to the given data. A deep copy may be performed if necessary
void	setData (const std::string &key, double data)
	set the given key to the given data. A deep copy may be performed if necessary
void	setData (const std::string &key, const double *data, unsigned count)
	set the given key to the given data. A deep copy may be performed if necessary
void	setData (const std::string &key, int data)
	set the given key to the given data. A deep copy may be performed if necessary
void	setData (const std::string &key, const int *data, unsigned count)
	set the given key to the given data. A deep copy may be performed if necessary
template<class T >

Detailed Description

a group of metadata, associated with keys to values. values consist of Doubles, Ints, or Strings, or arrays of same

Member Typedef Documentation

typedef std::shared_ptr<const Foundry::Property::Base> DD::Image::MetaData::Bundle::PropertyPtr

opaque data type for the metadata properties themselves. use helper functions isPropertyInt etc to access these

Member Function Documentation

const_iterator DD::Image::MetaData::Bundle::erase ( const_iterator  it )

inline

remove a particular piece of metadata. A deep copy may be performed if necessary return const_iterator following the last removed element or end() if it->first does not exist Note that existing iterators may be invalidated or no longer refer to this bundle including end()

const_iterator DD::Image::MetaData::Bundle::erase ( const char *  key )

inline

remove a particular piece of metadata. A deep copy may be performed if necessary return const_iterator following the last removed element or end() if key does not exist Note that existing iterators may be invalidated or no longer refer to this bundle including end()

MetaData::Bundle::const_iterator DD::Image::MetaData::Bundle::erase

(

const std::string &

key

)

remove a particular piece of metadata. A deep copy may be performed if necessary return const_iterator following the last removed element or end() if key does not exist Note that existing iterators may be invalidated or no longer refer to this bundle including end()

void DD::Image::MetaData::Bundle::setTimeStamp	(	const std::string &	key,
		const std::string &	timestamp
	)

set the given key to the given, which is in the format of the timestamp this will reformat 'YYYY:MM:DD HH:MM:SS', 'YYYY:MM:DD:HH:MM:SS', and 'YYYY-MM-DD HH-MM:SS' as the ISO 8601-compliant 'YYYY-MM-DD HH:MM:SS' A deep copy may be performed if necessary

void DD::Image::MetaData::Bundle::copyFrom

(

const Bundle &

otherBundle

)

copy all the data from the given metadata bundle Note that any existing keys will be replaced and a deep copy may be performed if necessary
