Method Detail

values

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

Returns:

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

valueOf

public static ECDSAPublicKeyEntryDecoder.ECPointCompression 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

                               String n,
                               BigInteger v,
                               int numElements)
                        throws IOException

Throws:

IOException

fromIndicatorValue

public static ECDSAPublicKeyEntryDecoder.ECPointCompression fromIndicatorValue(int value)

octetStringToInteger

public static BigInteger octetStringToInteger(byte... octets)

Converts the given octet string (defined by ASN.1 specifications) to a BigInteger As octet strings always represent positive integers, a zero-byte is prepended to the given array if necessary (if is MSB equal to 1), then this is converted to BigInteger The conversion is defined in the Section 2.3.8

Parameters:

octets - - octet string bytes to be converted

Returns:

The BigInteger representation of the octet string
