Enum Algorithm

java.lang.Object

java.lang.Enum<Algorithm>

org.jpos.security.Algorithm

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<Algorithm>

public enum Algorithm
extends java.lang.Enum<Algorithm>

Defines the cryptographic algorithm with which the key contained in the key block will be used.

Each value repesents byte 7 of the Keyblok Header.

Method Detail

values

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

Returns:

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

valueOf

public static Algorithm valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null

getCode

public char getCode()

Get algorithm code.

Returns:

character algorithm code

getName

public java.lang.String getName()

Get algorithm name.

Returns:

the algorithm name

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Enum<Algorithm>

valueOfByCode

public static Algorithm valueOfByCode(char code)

Returns the enum constant of this type with the specified code.

Parameters:

code - the string must match exactly with identifier specified by ISO 8583-1:2003(E) Table A.22 — Transaction type codes

Returns:

the enum constant with the specified processing code or null if unknown.
