Detailed Description

Root class that acts as an entry point to the SDF document model.

Multiple worlds can exist in a single SDF file. A user of multiple worlds could run parallel instances of simulation, or offer selection of a world at runtime.

Usage

In this example, a root object is loaded from a file specified in the first command line argument to a program.

  sdf::Root root;
  sdf::Errors errors = root.Load(argv[1]);
  if (errors.empty())
  {
    std::cerr << "Valid SDF file.\n";
    return 0;
  }
  else
  {
    std::cerr << "Errors encountered: \n";
    for (auto const &e : errors)
    {
      std::cout << e << std::endl;
    }
  }

Member Function Documentation

◆ ActorByIndex()

const Actor* sdf::v9::Root::ActorByIndex ( const uint64_t _index ) const

Get an actor based on an index.

Parameters

[in] _index Index of the actor. The actor should be in the range [0..ActorCount()).

Returns: Pointer to the actor. Nullptr if the index does not exist.

See also: uint64_t ActorCount() const

◆ ActorCount()

uint64_t sdf::v9::Root::ActorCount ( ) const

Get the number of actors.

Returns: Number of actors contained in this Root object.

◆ ActorNameExists()

bool sdf::v9::Root::ActorNameExists ( const std::string & _name ) const

Get whether an actor name exists.

Parameters

[in] _name Name of the actor to check.

Returns: True if there exists an actor with the given name.

◆ Element()

sdf::ElementPtr sdf::v9::Root::Element ( ) const

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

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

◆ LightByIndex()

const Light* sdf::v9::Root::LightByIndex ( const uint64_t _index ) const

Get a light based on an index.

Parameters

[in] _index Index of the light. The index should be in the range [0..LightCount()).

Returns: Pointer to the light. Nullptr if the index does not exist.

See also: uint64_t LightCount() const

◆ LightCount()

uint64_t sdf::v9::Root::LightCount ( ) const

Get the number of lights.

Returns: Number of lights contained in this Root object.

◆ LightNameExists()

bool sdf::v9::Root::LightNameExists ( const std::string & _name ) const

Get whether a light name exists.

Parameters

[in] _name Name of the light to check.

Returns: True if there exists a light with the given name.

◆ Load() [1/2]

Errors sdf::v9::Root::Load ( const std::string & _filename )

Parse the given SDF file, and generate objects based on types specified in the SDF file.

Parameters

[in] _filename Name of the SDF file to parse.

Returns: Errors, which is a vector of Error objects. Each Error includes an error code and message. An empty vector indicates no error.

◆ Load() [2/2]

Errors sdf::v9::Root::Load ( const SDFPtr _sdf )

Parse the given SDF pointer, and generate objects based on types specified in the SDF file.

Parameters

[in] _sdf SDF pointer to parse.

Returns: Errors, which is a vector of Error objects. Each Error includes an error code and message. An empty vector indicates no error.

◆ LoadSdfString()

Errors sdf::v9::Root::LoadSdfString ( const std::string & _sdf )

Parse the given SDF string, and generate objects based on types specified in the SDF file.

Parameters

[in] _sdf SDF string to parse.

Returns: Errors, which is a vector of Error objects. Each Error includes an error code and message. An empty vector indicates no error.

◆ ModelByIndex()

const Model* sdf::v9::Root::ModelByIndex ( const uint64_t _index ) const

Get a model based on an index.

Parameters

[in] _index Index of the model. The index should be in the range [0..ModelCount()).

Returns: Pointer to the model. Nullptr if the index does not exist.

See also: uint64_t ModelCount() const

◆ ModelCount()

uint64_t sdf::v9::Root::ModelCount ( ) const

Get the number of models.

Returns: Number of models contained in this Root object.

◆ ModelNameExists()

bool sdf::v9::Root::ModelNameExists ( const std::string & _name ) const

Get whether a model name exists.

Parameters

[in] _name Name of the model to check.

Returns: True if there exists a model with the given name.

◆ SetVersion()

void sdf::v9::Root::SetVersion ( const std::string & _version )

Set the SDF version string.

Parameters

[in] _version The new SDF version.

See also: std::string Version()

◆ Version()

std::string sdf::v9::Root::Version ( ) const

Get the SDF version specified in the parsed file or SDF pointer.

Returns: SDF version string.

See also: void SetVersion(const std::string &_version)

◆ WorldByIndex()

const World* sdf::v9::Root::WorldByIndex ( const uint64_t _index ) const

Get a world based on an index.

Parameters

[in] _index Index of the world. The index should be in the range [0..WorldCount()).

Returns: Pointer to the world. Nullptr if the index does not exist.

See also: uint64_t WorldCount() const

◆ WorldCount()

uint64_t sdf::v9::Root::WorldCount ( ) const

Get the number of worlds.

Returns: Number of worlds contained in this Root object.
