Method Detail

encode

public static void encode(ByteBuffer buffer,
                          Asn1Type value)
                   throws IOException

Encode value into buffer.

Parameters:

buffer -

value -

Throws:

IOException

encode

public static byte[] encode(Asn1Type value)
                     throws IOException

Encode value and return the result.

Parameters:

value -

Returns:

Throws:

IOException

decode

public static Asn1Type decode(byte[] content)
                       throws IOException

Blindly decode content and return the result ASN1 object.

Parameters:

content -

Returns:

Throws:

IOException

decode

public static Asn1Type decode(ByteBuffer content)
                       throws IOException

See avove.

Throws:

IOException

decode

public static void decode(byte[] content,
                          Asn1Type value)
                   throws IOException

Decode using specified value container. Better to use this when the value type is known prior to the call.

Parameters:

content -

value -

Throws:

IOException

decode

public static void decode(ByteBuffer content,
                          Asn1Type value)
                   throws IOException

See avove.

Throws:

IOException

parse

public static Asn1ParseResult parse(byte[] content)
                             throws IOException

Parse content and return parse result. Note this is different from decode, as it doesn't decode into values, only parse result info like offset, header len, body len and etc. are out.

Parameters:

content -

Returns:

Throws:

IOException

parse

public static Asn1ParseResult parse(ByteBuffer content)
                             throws IOException

See avove.

Throws:

IOException

dump

public static void dump(Asn1Type value)

Dump out a value.

Parameters:

value -

parseAndDump

public static void parseAndDump(String hexStr)
                         throws IOException

Parse first, and then dump out the parse result.

Parameters:

hexStr -

Throws:

IOException

parseAndDump

public static void parseAndDump(ByteBuffer content)
                         throws IOException

See avove.

Throws:

IOException

parseAndDump

public static void parseAndDump(byte[] content)
                         throws IOException

See avove.

Throws:

IOException

decodeAndDump
