Detailed Description

Constant storage for WKB.

Encapsulation and the available methods make it impossible to update the members of wkb_container once it is initialized. The only allowed modification method is set(), which fully replaces the previous buffer.

length()

uint32 Geometry::wkb_container::length ( ) const

no_data()

bool Geometry::wkb_container::no_data ( size_t  data_amount ) const

inline

Check if there's enough data remaining as requested.

• data_amount data requested

Returns

true if not enough data

not_enough_points()

bool Geometry::wkb_container::not_enough_points ( uint32  expected_points, uint32  extra_point_space = 0  ) const

inline

Check if there're enough points remaining as requested.

Need to perform the calculation in logical units, since multiplication can overflow the size data type.

• expected_points number of points expected
• extra_point_space extra space for each point element in the array

Returns

true if there are not enough points

set()

void Geometry::wkb_container::set ( const char *  data, const char *  data_end  )
