Detailed Description

Base class of all WKB parsers, which parse different types of geometries properly.

All these classes assume the WKB input is valid and complete.

Constructor & Destructor Documentation

Stepper_base()

Stepper_base::Stepper_base ( char  dim, Geometry::wkbByteOrder  bo, bool  has_wkb_hdr, Geometry::wkbType  geotype  )

Constructor.

Parameters

dim	dimension of points in the geometry to be stepped over(i.e. current geometry).
bo	current geometry's byte order
has_wkb_hdr	true for stepping through geometries within multiXXX and geometrycollection, false for other geometries.
geotype	current geometry's type
