Method Detail

values

public static BuiltinDHFactories[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (BuiltinDHFactories c : BuiltinDHFactories.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static BuiltinDHFactories valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getName

public final String getName()

Specified by:

getName in interface NamedResource

Returns:

The resource name

isSupported

public boolean isSupported()

Specified by:

isSupported in interface OptionalFeature

toString

public final String toString()

Overrides:

toString in class Enum<BuiltinDHFactories>

registerExtension

public static void registerExtension(DHFactory extension)

Registered a NamedFactory to be available besides the built-in ones when parsing configuration

Parameters:

extension - The factory to register

Throws:

IllegalArgumentException - if factory instance is null, or overrides a built-in one or overrides another registered factory with the same name (case insensitive).

getRegisteredExtensions

public static SortedSet<DHFactory> getRegisteredExtensions()

Returns:

A SortedSet of the currently registered extensions, sorted according to the factory name (case insensitive)

unregisterExtension

public static DHFactory unregisterExtension(String name)

Unregisters specified extension

Parameters:

name - The factory name - ignored if null/empty

Returns:

The registered extension - null if not found

fromFactoryName

public static BuiltinDHFactories fromFactoryName(String name)

Parameters:

name - The factory name - ignored if null/empty

Returns:

The matching BuiltinDHFactories (case insensitive) or null if no match found

isGroupExchange

public boolean isGroupExchange()

Specified by:

isGroupExchange in interface DHFactory

parseDHFactoriesList

public static BuiltinDHFactories.ParseResult parseDHFactoriesList(String dhList)

Parameters:

dhList - A comma-separated list of ciphers' names - ignored if null/empty

Returns:

A BuiltinDHFactories.ParseResult of all the DHFactory-ies whose name appears in the string and represent a built-in value. Any unknown name is ignored. The order of the returned result is the same as the original order - bar the unknown ones. Note: it is up to caller to ensure that the list does not contain duplicates

parseDHFactoriesList

public static BuiltinDHFactories.ParseResult parseDHFactoriesList(String... dhList)

parseDHFactoriesList

public static BuiltinDHFactories.ParseResult parseDHFactoriesList(Collection<String> dhList)

resolveFactory

public static DHFactory resolveFactory(String name)

Parameters:

name - The factory name

Returns:

The factory or null if it is neither a built-in one or a registered extension
