Method Details

values

public static MacAlgorithm[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static MacAlgorithm valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null

getName

public String getName()

Returns the algorithm name.

Specified by:

getName in interface JwaAlgorithm

Returns:

the algorithm name

from

public static MacAlgorithm from(String name)

Attempt to resolve the provided algorithm name to a MacAlgorithm.

Parameters:

name - the algorithm name

Returns:

the resolved MacAlgorithm, or null if not found
