Constructor Detail

ASN1UTF8String

public ASN1UTF8String()

Creates an instance.

ASN1UTF8String

public ASN1UTF8String(String s)

Parameters:

s - The string value.

Method Detail

getTag

public int getTag()

Returns the tag of this class.

Overrides:

getTag in class ASN1AbstractType

Returns:

The tag.

setString0

protected void setString0(String s)

Overrides:

setString0 in class ASN1AbstractString

convert

public String convert(byte[] b)
               throws ASN1Exception

Converts the given byte array to a string. The byte array must be in UTF-8 encoding.

Overrides:

convert in class ASN1AbstractString

Parameters:

b - The byte array to convert.

convert

public byte[] convert(String s)
               throws ASN1Exception

Converts the given string to a byte array. The byte array contains the UTF-8 encoding of the given String.

Overrides:

convert in class ASN1AbstractString

Parameters:

s - The string to convert.

convertedLength

public int convertedLength(String s)
                    throws ASN1Exception

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

Overrides:

convertedLength in class ASN1AbstractString

Parameters:

s - The string.
