createAlgorithms

public static List<Algorithm> createAlgorithms(InputStream configuration)
                                        throws AlgorithmException

Creates a list of algorithms and initialises them with the parameters provided in the configuration object.

Parameters:

configuration - the input stream from where the XML configuration can be read from.

Returns:

the list of algorithms.

Throws:

AlgorithmException - if the algorithms could not be created.

createAlgorithms

public static List<Algorithm> createAlgorithms(Configuration config)
                                        throws AlgorithmException

Creates a list of algorithms and initialises them with the parameters provided in the configuration object.

Parameters:

config - the configuration object.

Returns:

the list of algorithms.

Throws:

AlgorithmException - if the algorithms could not be created.

createAlgorithm

public static Algorithm createAlgorithm(InputStream configuration)
                                 throws AlgorithmException

Instantiates an algorithm with a specific configuration object.

Parameters:

configuration - the input stream from which the XML configuration can be read from.

Returns:

the initialised algorithm.

Throws:

AlgorithmException - if the algorithm could not be created.

createAlgorithm

public static Algorithm createAlgorithm(InputStream config,
                                        InputStream set)
                                 throws AlgorithmException

Creates a new algorithm instance.

Parameters:

config - the input stream from which the XML configuration can be read from.

set - the input stream from which the XML gesture set can be read from.

Returns:

the initialised algorithm.

Throws:

AlgorithmException - if the algorithm could not be created.

createAlgorithm

public static Algorithm createAlgorithm(Configuration config)
                                 throws AlgorithmException

Instantiates an algorithm with a given configuration object.

Parameters:

config - the configuration of the algorithm.

Returns:

the initialised algorithm.

Throws:
