Detailed Description

template<typename Point_3>
class Gudhi::Points_3D_off_visitor_reader< Point_3 >

OFF file visitor implementation according to Off_reader in order to read points from an OFF file.

Member Function Documentation

get_point_cloud()

template<typename Point_3 >

const std::vector< Point_3 > & Gudhi::Points_3D_off_visitor_reader< Point_3 >::get_point_cloud ( ) const

inline

Point cloud getter.

Returns

The point cloud.

init()

template<typename Point_3 >

void Gudhi::Points_3D_off_visitor_reader< Point_3 >::init ( int  dim, int  num_vertices, int  num_faces, int  num_edges  )

inline

Off_reader visitor init implementation.

The init parameters are set from OFF file header. Dimension value is required and the value must be 3.

Parameters

[in]	dim	space dimension of vertices.
[in]	num_vertices	number of vertices in the OFF file (not used).
[in]	num_faces	number of faces in the OFF file (not used).
[in]	num_edges	number of edges in the OFF file (not used).

is_valid()

template<typename Point_3 >

bool Gudhi::Points_3D_off_visitor_reader< Point_3 >::is_valid ( ) const

inline

Returns if the OFF file read operation was successful or not.

Returns

OFF file read status.

point()

template<typename Point_3 >

void Gudhi::Points_3D_off_visitor_reader< Point_3 >::point ( const std::vector< double > &  point )

inline

Off_reader visitor point implementation.

The point function is called on each vertex line from OFF file. This function inserts the vertex in the vector of points.

Parameters

[in]

point

vector of vertex coordinates.

Point_3 must have a constructor with the following form:

template<class InputIterator > Point_3::Point_3(double x, double y, double z)
