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>.

template<typename T>

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

Solver type.

Constructor & Destructor Documentation

template<typename T >

roboptim::SolverFactory< T >::SolverFactory	(	std::string	solver,
		const problem_t &	problem
	)		throw (std::runtime_error) [explicit]

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

throw ()

Unload the plug-in and free the instantiated solver.

throw ()

Retrieve a reference on the solver.

Returns:

reference on a solver
