Method Detail

values

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

Returns:

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

valueOf

public static SymmetricKeyAlgorithm 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

fromId

public static SymmetricKeyAlgorithm fromId(int id)

Return the SymmetricKeyAlgorithm enum that corresponds to the provided numeric id. If an invalid id is provided, null is returned.

Parameters:

id - numeric algorithm id

Returns:

symmetric key algorithm enum

getAlgorithmId

public int getAlgorithmId()

Return the numeric algorithm id of the enum.

Returns:

numeric id
