Detailed Description

Polyline represents a 2D path. Multiple polylines can be combined.

Constructor & Destructor Documentation

◆ Polyline()

sdf::SDF_VERSION_NAMESPACE::Polyline::Polyline ( )

Constructor.

Member Function Documentation

◆ AddPoint()

bool sdf::SDF_VERSION_NAMESPACE::Polyline::AddPoint ( const gz::math::Vector2d &  _point)

Add a point to the polyline.

Parameters
[in]_point2D point to add.
Returns
True for success.

◆ ClearPoints()

void sdf::SDF_VERSION_NAMESPACE::Polyline::ClearPoints ( )

Remove all points from the polyline.

◆ Element()

sdf::ElementPtr sdf::SDF_VERSION_NAMESPACE::Polyline::Element ( ) const

Get a pointer to the SDF element that was used during load.

Returns
SDF element pointer. The value will be nullptr if Load has not been called.

◆ Height()

double sdf::SDF_VERSION_NAMESPACE::Polyline::Height ( ) const

Get the polyline's height in meters.

Returns
The height of the polyline in meters.

◆ Load()

Errors sdf::SDF_VERSION_NAMESPACE::Polyline::Load ( ElementPtr  _sdf)

Load the polyline geometry based on an element pointer.

This is not the usual entry point. Typical usage of the SDF DOM is through the Root object.

Parameters
[in]_sdfThe SDF Element pointer
Returns
Errors, which is a vector of Error objects. Each Error includes an error code and message. An empty vector indicates no error.

◆ PointByIndex() [1/2]

gz::math::Vector2d * sdf::SDF_VERSION_NAMESPACE::Polyline::PointByIndex ( uint64_t  _index)

Get a point by its index.

Returns
Mutable pointer to the point.

◆ PointByIndex() [2/2]

const gz::math::Vector2d * sdf::SDF_VERSION_NAMESPACE::Polyline::PointByIndex ( uint64_t  _index) const

Get a point by its index.

Returns
Constant pointer to the point.

◆ PointCount()

uint64_t sdf::SDF_VERSION_NAMESPACE::Polyline::PointCount ( ) const

Get the number of points.

Returns
Number of points.

◆ Points()

const std::vector< gz::math::Vector2d > & sdf::SDF_VERSION_NAMESPACE::Polyline::Points ( ) const

Get the polyline's points.

Each point has 2D coordinates in meters.

Returns
The polyline's points.

◆ SetHeight()

void sdf::SDF_VERSION_NAMESPACE::Polyline::SetHeight ( const double  _height)

Set the polyline's height in meters.

Parameters
[in]_heightThe height of the polyline in meters.

◆ ToElement() [1/2]

sdf::ElementPtr sdf::SDF_VERSION_NAMESPACE::Polyline::ToElement ( ) const

Create and return an SDF element filled with data from this polyline.

Note that parameter passing functionality is not captured with this function.

Returns
SDF element pointer with updated polyline values.

◆ ToElement() [2/2]

sdf::ElementPtr sdf::SDF_VERSION_NAMESPACE::Polyline::ToElement ( sdf::Errors _errors) const

Create and return an SDF element filled with data from this polyline.

Note that parameter passing functionality is not captured with this function.

Parameters
[in]_errorsVector of errors.
Returns
SDF element pointer with updated polyline values.
