Member Function Documentation

bool lti::loadLnc::apply	(	dmatrix &	vcts,
		ivector &	ids,
		std::vector< std::string > &	attribs
	)

load all the vectors in the file and leave the results in the given matrix.

The i-th row of the matrix will be the i-th vector on the file.

Parameters:

	vcts	the matrix where the vectors will be written
	ids	a vector, the class ids for each vector in the matrix. The i-th element of the vector contains the id of the i-th row of the matrix.
	attribs	a vector of std::string with the attributes for each pattern in the file

Returns:

true if everything is ok or false if the file is corrupted or not found.

bool lti::loadLnc::apply	(	dmatrix &	vcts,
		ivector &	ids,
		std::vector< std::string > &	attribs,
		std::map< int, std::string > &	names
	)

load all the vectors in the file and leave the results in the given matrix.

The i-th row of the matrix will be the i-th vector on the file.

Parameters:

	vcts	the matrix where the vectors will be written
	ids	a vector the class ids for each vector in the matrix. The i-th element of the vector contains the id of the i-th row of the matrix.
	attribs	a vector of std::string with the attributes for each pattern in the file
	names	a table with the corresponding names for each object id

Returns:

true if everything is ok or false if the file is corrupted or not found.

bool lti::loadLnc::apply	(	dmatrix &	vcts,
		ivector &	ids,
		std::map< int, std::string > &	names
	)

load all the vectors in the file and leave the results in the given matrix.

The i-th row of the matrix will be the i-th vector on the file.

Parameters:

	vcts	the matrix where the vectors will be written
	ids	a vector the class ids for each vector in the matrix. The i-th element of the vector contains the id of the i-th row of the matrix.
	names	a table with the corresponding names for each object id

Returns:

true if everything is ok or false if the file is corrupted or not found.

bool lti::loadLnc::apply	(	dmatrix &	vcts,
		ivector &	ids
	)

load all the vectors in the file and leave the results in the given matrix.

The i-th row of the matrix will be the i-th vector on the file.

Parameters:

	vcts	the matrix where the vectors will be written
	ids	a vector the class ids for each vector in the matrix. The i-th element of the vector contains the id of the i-th row of the matrix.

Returns:

true if everything is ok or false if the file is corrupted or not found.

bool lti::loadLnc::apply	(	dvector &	vct,
		patternId &	id
	)

load the next vector in the file.

Parameters:

	vct	the vector object, where the readed data will be written
	id	the id of the class the vector belongs to.

Returns:

true if everything is ok, false if there is no more data left on the file. If the file is corrupted, a lti::exception will be thrown.

	)

shortcut to read the given lnc file, ignoring the filenames

Parameters:

	filename	name of the file to be loaded
	vcts	the matrix where the vectors will be written
