Constructor Detail

AlgorithmRegistryImpl

public AlgorithmRegistryImpl()

Default constructor.

AlgorithmRegistryImpl

public AlgorithmRegistryImpl(List<Algorithm> registry)

Constructor setting up the registry according to the supplied list.

Note: a copy of the supplied registry is made.

Parameters:

registry - initial contents of the registry

Method Detail

register

public void register(Algorithm algorithm)

Registers the given algorithm in the registry.

Parameters:

algorithm - the algorithm to register

unregister

public void unregister(String algorithmUri)

Removes the given algorithm from the registry.

Parameters:

algorithmUri - the algorithm URI

getAlgorithm

public Algorithm getAlgorithm(String algorithmUri)

Gets the algorithm based on its URI.

Specified by:

getAlgorithm in interface AlgorithmRegistry

Parameters:

algorithmUri - the algorithm URI

Returns:

the algorithm, or null if none is found

getAlgorithm

public <T extends Algorithm> T getAlgorithm(String algorithmUri,
                                            Class<T> clazz)

Gets an algorithm based on its URI and type.

Specified by:

getAlgorithm in interface AlgorithmRegistry

Type Parameters:

T - the algorithm type

Parameters:

algorithmUri - the algorithm URI

clazz - the type representing the algorithm

Returns:

the algorithm, or null if none is found

getAlgorithm

public <T extends Algorithm> T getAlgorithm(Predicate<Algorithm> predicate,
                                            Class<T> clazz)

Gets the first algorithm that matches the given type and supplied predicate.

If more than one algorithm matches the supplied predicate, the one with the lowest order is returned.

Specified by:

getAlgorithm in interface AlgorithmRegistry

Parameters:

predicate - the predicate to apply

clazz - the type representing the algorithm

Returns:

an Algorithm or null if no algorithms in the registry matches

AlgorithmPredicates

getAlgorithm

public Algorithm getAlgorithm(Predicate<Algorithm> predicate)

Gets the first algorithm that matches the supplied predicate.

If more than one algorithm matches the supplied predicate, the one with the lowest order is returned.

Specified by:

getAlgorithm in interface AlgorithmRegistry

Parameters:

predicate - the predicate to apply

Returns:

an Algorithm or null if no algorithms in the registry matches

See Also:

getAlgorithms

public List<Algorithm> getAlgorithms(Predicate<Algorithm> predicate)

Gets all algorithms that matches the supplied predicate.

The list is sorted with the lowest algorithms with the lowest order index first.

Specified by:

getAlgorithms in interface AlgorithmRegistry

Parameters:

predicate - the predicate to apply

Returns:

a (possibly empty) list of Algorithm objects

getAlgorithms

public <T extends Algorithm> List<T> getAlgorithms(Predicate<Algorithm> predicate,
                                                   Class<T> clazz)

Gets all algorithms that matches the given type and the supplied predicate.

The list is sorted with the lowest algorithms with the lowest order index first.

Specified by:

getAlgorithms in interface AlgorithmRegistry

Parameters:

predicate - the predicate to apply

clazz - the type representing the algorithm

Returns:

a (possibly empty) list of Algorithm objects
