Public Member Functions

 Bundle ()
 create an empty bundle
 Bundle (const MetaData::Bundle &otherBundle)
void operator= (const MetaData::Bundle &otherBundle)
size_t size () const
 how many metadata elements there are in this bundle
iterator begin ()
 get iterator to the first piece of metadata
iterator end ()
 get iterator pointing past the last piece of metadata
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
iterator find (const char *key)
 find a particular piece of metadata by key. returns end() if not present.
iterator find (const std::string &key)
 find a particular piece of metadata by key. returns end() if not present.
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.
void erase (iterator it)
 remove a particular piece of metadata, without deleting the object
void erase (const char *key)
 remove a particular piece of metadata, without deleting the object
void erase (const std::string &key)
 remove a particular piece of metadata, without deleting the object
const data_tmeta () const
 return the underlying std::map for the metadata

 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.

void setData (const std::string &key, const PropertyPtr &property)

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 Foundry::Property::Base* DD::Image::MetaData::Bundle::PropertyPtr

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


Constructor & Destructor Documentation

DD::Image::MetaData::Bundle::Bundle ( const MetaData::Bundle otherBundle)

create a new bundle based upon other bundles. this will be a deep copy, all the properties will be copied as well.


Member Function Documentation

void DD::Image::MetaData::Bundle::operator= ( const MetaData::Bundle otherBundle)

assign this bundle based upon another bundle. this will be a deep copy, all the properties will be copied as well

void DD::Image::MetaData::Bundle::setData ( const std::string &  key,
const PropertyPtr property 
) [protected]

set the given key to point at the given object, which the bundle now takes ownership of

Referenced by DD::Image::Read::_fetchMetaData(), and setDataIfNotNan().

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'
