Constructor Detail

ASN1UniversalString

public ASN1UniversalString()

ASN1UniversalString

public ASN1UniversalString(String s)

Creates an instance with the given string value. No constraints could be set yet so none are checked.

Parameters:

s - The string value.

Method Detail

getTag

public int getTag()

Returns the ASN.1 tag of this type.

Overrides:

getTag in class ASN1AbstractType

Returns:

The tag value.

convert

public String convert(byte[] b)
               throws ASN1Exception

Converts the given byte array to a string by reading four bytes per character from the array and concatenating them into a Unicode character.

Overrides:

convert in class ASN1AbstractString

Parameters:

b - The byte array to convert.

convert

public byte[] convert(String s)

Converts the given string to a byte array where each character is transformed into 4 consecutive bytes.

Overrides:

convert in class ASN1AbstractString

Parameters:

s - The string to convert.

convertedLength

public int convertedLength(String s)

Returns the number of bytes required to store the converted string.

Overrides:

convertedLength in class ASN1AbstractString

Parameters:

s - The string.
