Method Detail

values

public static BuiltinDigests[] 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 (BuiltinDigests c : BuiltinDigests.values())
    System.out.println(c);

Returns:

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

valueOf

public static BuiltinDigests 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

getAlgorithm

public final String getAlgorithm()

Specified by:

getAlgorithm in interface AlgorithmNameProvider

getBlockSize

public final int getBlockSize()

Specified by:

getBlockSize in interface DigestInformation

Returns:

The number of bytes in the digest's output

toString

public final String toString()

Overrides:

toString in class Enum<BuiltinDigests>

create

public final Digest create()

Specified by:

create in interface Factory<Digest>

Returns:

A new instance

isSupported

public final boolean isSupported()

Specified by:

isSupported in interface OptionalFeature

fromString

public static BuiltinDigests fromString(String s)

Parameters:

s - The Enum's name - ignored if null/empty

Returns:

The matching BuiltinDigests whose Enum.name() matches (case insensitive) the provided argument - null if no match

fromFactory

public static BuiltinDigests fromFactory(NamedFactory<? extends Digest> factory)

Parameters:

factory - The NamedFactory for the cipher - ignored if null

Returns:

The matching BuiltinDigests whose factory name matches (case insensitive) the digest factory name

See Also:

fromFactoryName(String)

fromFactoryName

public static BuiltinDigests fromFactoryName(String name)

Parameters:

name - The factory name - ignored if null/empty

Returns:

The matching BuiltinDigests whose factory name matches (case insensitive) the provided name - null if no match

fromDigest

public static BuiltinDigests fromDigest(Digest d)

Parameters:

d - The Digest instance - ignored if null

Returns:

The matching BuiltinDigests whose algorithm matches (case insensitive) the digets's algorithm - null if no match

fromAlgorithm

public static BuiltinDigests fromAlgorithm(String algo)

Parameters:

algo - The algorithm to find - ignored if null/empty

Returns:

The matching BuiltinDigests whose algorithm matches (case insensitive) the provided name - null if no match
