Detailed Description

IRI ROS Specific Driver Class.

Definition at line 51 of file svmsgd_alg.h.

Member Typedef Documentation

typedef iri_svmsgd::SvmsgdConfig SvmsgdAlgorithm::Config

define config type

Define a Config type with the SvmsgdConfig. All driver implementations will then use the same variable type Config.

Definition at line 110 of file svmsgd_alg.h.

Constructor & Destructor Documentation

SvmsgdAlgorithm::SvmsgdAlgorithm ( void )

constructor

In this constructor parameters related to the specific driver can be initalized. Those parameters can be also set in the openDriver() function. Attributes from the main node driver class IriBaseDriver such as loop_rate, may be also overload here.

Definition at line 3 of file svmsgd_alg.cpp.

SvmsgdAlgorithm::~SvmsgdAlgorithm ( void )

Destructor.

This destructor is called when the object is about to be destroyed.

Definition at line 24 of file svmsgd_alg.cpp.

Member Function Documentation

void SvmsgdAlgorithm::add_to_dense_vec	(	const std::vector< float > &	vec1,
		double	alpha,
		double *	vec2
	)		`[inline, protected]`

Definition at line 79 of file svmsgd_alg.h.

void SvmsgdAlgorithm::add_to_dense_vec_abs	(	const std::vector< float > &	vec1,
		double	alpha,
		double *	vec2
	)		`[inline, protected]`

Definition at line 85 of file svmsgd_alg.h.

void SvmsgdAlgorithm::config_update	(	Config &	new_cfg,
		uint32_t	level = `0`
	)

config update

In this function the driver parameters must be updated with the input config variable. Then the new configuration state will be stored in the Config attribute.

Parameters:
