Method Detail

getInstance

public static NamedCurveRegistrySingleton getInstance()

Gets the singleton instance.

Returns:

the singleton instance

setAlgorithmRegistry

public static void setAlgorithmRegistry(NamedCurveRegistry registry)

Assigns the NamedCurveRegistry instance to be used by this singleton. If no instance is assigned, a default implementation of the registry will be used.

Parameters:

registry - the registry to be used by the singleton

getCurve

public NamedCurve getCurve(String name)

Gets a NamedCurve based on its name.

Specified by:

getCurve in interface NamedCurveRegistry

Parameters:

name - the name

Returns:

the NamedCurve or null if no match is found

getCurve

public NamedCurve getCurve(Predicate<NamedCurve> predicate)

Gets a NamedCurve based on the given predicate.

Specified by:

getCurve in interface NamedCurveRegistry

Parameters:

predicate - the predicate

Returns:

the first curve that matches the supplied predicate, or null if no matches are found

getCurves

public List<NamedCurve> getCurves(Predicate<NamedCurve> predicate)

Gets all curves that matches the given predicate.

Specified by:

getCurves in interface NamedCurveRegistry

Parameters:

predicate - the predicate

Returns:

a (possibly empty) list of NamedCurve objects
