Classes
struct	Attribute
struct	MappingEntry

Public Types
enum	StorageClass { constant = 1, variable = 2, dynamic = 3 }
enum	CompressionOptions { default_ = 0, delta = 1, shuffle = 2, delta_shuffle = 3 }

Public Member Functions
virtual unsigned	getAttributeCount () const =0
	get number of attribute (available after header was read)
virtual void	getAttribute (unsigned idx, Attribute &attr) const =0
	get corresponding attribute record (available after header was read)
virtual void	importAttribute (int rdbAttrIndex, int arrayIdx=0, ColumnSemantic ngCol=ColumnSemantic::null, const char *filterString="")=0
	Specify a predefined NG-attribute by its enum. The rdb attribute's type will be converted to that of the predefined attribute.
virtual void	importAttribute (int rdbAttrIndex, int arrayIdx=0, const char *ngName=0, ColumnType ngType=ColumnType::count, const char *filterString="")=0
	Specify the NG-attribute by name. By default, use the name and type of the rdb attribute.

Member Enumeration Documentation

CompressionOptions

enum CompressionOptions

strong

Enumerator
default_	nothing special, just use default compression algorithm
delta	calculate differences between two consecutive values
shuffle	shuffle bytes of point attribute values
delta_shuffle	calculate differences and shuffle bytes

StorageClass

enum StorageClass

strong

Enumerator
constant	value cannot be changed
variable	value can change from time to time
dynamic	value is likely to be changed often
