Detailed Description

template<typename T>
class roboptim::SolverFactory< T >

Define a solver factory that instanciate the plug-ins.

The solver factory has to be used to instantiate solvers which are packaged as roboptim-core plug-ins.

This class uses libltdl to handle plug-ins. This lightweight library is provided with GNU Libtool and wraps OS specific behavior into a uniform interface.

Warning

The solver lifetime is bound to the factory lifetime, when the factory goes out of scope, the solver is destroyed too.

Template Parameters

T	solver type

Precondition

T has to be a subtype of Solver<F,C>.

Member Typedef Documentation

problem_t

template<typename T>

typedef T::problem_t roboptim::SolverFactory< T >::problem_t

Problem type.

solver_t

template<typename T>

typedef T roboptim::SolverFactory< T >::solver_t

Solver type.

Member Function Documentation

operator()()

template<typename T>

SolverFactory< T >::solver_t & roboptim::SolverFactory< T >::operator()

(

)

Instantiate a factory and load the plug-in.

The constructor search for the plug-in and load it. If the wanted plug-in can not be found, an exception is thrown.

Parameters

solver	solver name (for instance ``cfsqp'')
problem	problem that will be solved

Exceptions

std::runtime_error

*/ explicit SolverFactory (std::string solver, const problem_t& problem);

/ Unload the plug-in and free the instantiated solver. ~SolverFactory ();

/** Retrieve a reference on the solver.

Returns

reference on a solver
