Method Detail

values

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

Returns:

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

valueOf

public static DigestAlgorithm 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

fromString

public static DigestAlgorithm fromString(String algorithmName,
                                         DigestAlgorithm defaultAlgorithm)

Gets the digest algorithm from an algorithm name

Parameters:

algorithmNam - The digest algorithm name

defaultAlgorithm - The default algorithm to return is a corresponding name cannot be found

Returns:

A digest algorithm enumeration object corresponding the name
