Access to metrics.
Objects which describe space-time geometry must inherit from the Gyoto::Metric::Generic class.
To be usable, a Metric::Generic sub-class should register a Metric::Subcontractor_t function using the Metric::Register() function. See also Writing plug-ins for Gyoto .
typedef SmartPointer< Metric::Generic > Gyoto::Metric::Subcontractor_t(FactoryMessenger *, std::vector< std::string > const &) |
A function to build instances of a specific Metric::Generic sub-class.
This is a more specific version of the SmartPointee::Subcontractor_t type. A Metric::Subcontrator_t is called by the Gyoto::Factory to build an instance of the kind of metric specified in an XML file (see Register()). The Factory and Subcontractor_t function communicate through a Gyoto::FactoryMessenger.
Gyoto::Metric::Subcontractor_t * Gyoto::Metric::getSubcontractor | ( | std::string | name, |
std::vector< std::string > & | plugin, | ||
int | errmode = 0 |
||
) |
Query the Metric register.
Query the Metric register to get the Metric::Subcontractor_t correspondig to a given kind name. This function is normally called only from the Factory. If plugin is specified, only a subcontractor matching both name and plugin will be returned, loading the plug-in if necessary. If plugin is the empty string, then the first subcontractor matching name will be returned, and the name of the plug-in it belongs to will be returned in plugin upon output.
[in] | name | e.g. "KerrBL" |
[in,out] | plugin | e.g. "stdplug". |
[in] | errmode | int=0. If errmode==0, failure to find a registered Metric by that name is an error. Else, simply return NULL pointer in that case. |
void Gyoto::Metric::initRegister | ( | ) |
Empty the Metric register.
This must be called once. It is called by Gyoto::Register::init().
void Gyoto::Metric::Register | ( | std::string | kind, |
Gyoto::Metric::Subcontractor_t * | scp | ||
) |
Make a Metric kind known to the Factory.
Register a new Metric::Generic sub-class so that the Gyoto::Factory knows it.
kind | The kind name which identifies this object type in an XML file, as in <Metric kind="name"> |
scp | A pointer to the subcontractor, which will communicate with the Gyoto::Factory to build an instance of the class from its XML description |
SmartPointer< Metric::Generic > Gyoto::Metric::Subcontractor | ( | FactoryMessenger * | fmp, |
std::vector< std::string > const & | plugins | ||

Subcontractor template.
Instead of reimplementing the wheel, your subcontractor can simply be Gyoto::Metric::Subcontractor<MyKind>
T | Sub-class of Metric::Generic |

The Metric register.
Use the Metric::initRegister() once in your program to initiliaze it, the Metric::Register() function to fill it, and the Metric::getSubcontractor() function to query it.
