Classes
class	StreamMetadata
	Container for metadata describing how to unserialize grids from and/or serialize grids to a stream (which file format, compression scheme, etc. to use) More...
struct	MultiPass
	Leaf nodes that require multi-pass I/O must inherit from this struct. More...
class	MappedFile
	Handle to control the lifetime of a memory-mapped .vdb file. More...
