Method Detail

values

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

Returns:

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

valueOf

public static CryptoProtocolVersion 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

supported

public static CryptoProtocolVersion[] supported()

Returns:

Array of supported protocol versions.

supports

public static boolean supports(CryptoProtocolVersion version)

Returns if a given protocol version is supported.

Parameters:

version - version number

Returns:

true if the version is supported, else false

setUnknownValue

public void setUnknownValue(int unknown)

getUnknownValue

public int getUnknownValue()

getDescription

public java.lang.String getDescription()

getVersion

public int getVersion()

toString

public java.lang.String toString()

Overrides:
