// Class : EggData
|
|
// Description : This is the primary interface into all the egg data,
|
|
// and the root of the egg file structure. An EggData
|
|
// structure corresponds exactly with an egg file on the
|
|
// disk.
|
|
//
|
|
// The EggData class inherits from EggGroupNode its
|
|
// collection of children, which are accessed by using
|
|
// the EggData itself as an STL container with begin()
|
|
// and end() calls. The children of the EggData class
|
|
// are the toplevel nodes in the egg file.
