GSF.ASN1 BER OID Encoding Implemented by Alan Gutzeit.

Adds encoding to passed result array. Note that result array must already have adequate capacity.

Decode of the constrained whole number ITU-T X.691. 10.5. NOTE – (Tutorial) This subclause is referenced by other clauses, and itself references earlier clauses for the production of a nonnegative-binary-integer or a 2's-complement-binary-integer encoding.

Decode the semi-constrained whole number ITU-T X.691. 10.7. NOTE – (Tutorial) This procedure is used when a lower bound can be identified but not an upper bound. The encoding procedure places the offset from the lower bound into the minimum number of octets as a non-negative-binary-integer, and requires an explicit length encoding (typically a single octet) as specified in later procedures.

Decode the normally small number ITU-T X.691. 10.6 NOTE – (Tutorial) This procedure is used when encoding a non-negative whole number that is expected to be small, but whose size is potentially unlimited due to the presence of an extension marker. An example is a choice index.

Decode the unconstrained whole number ITU-T X.691. 10.8. NOTE – (Tutorial) This case only arises in the encoding of the value of an integer type with no lower bound. The procedure encodes the value as a 2's-complement-binary-integer into the minimum number of octets required to accommodate the encoding, and requires an explicit length encoding (typically a single octet) as specified in later procedures.

Encoding of the choice structure ITU-T X.691. 22. NOTE – (Tutorial) A choice type is encoded by encoding an index specifying the chosen alternative. This is encoded as for a constrained integer (unless the extension marker is present in the choice type, in which case it is a normally small non-negative whole number) and would therefore typically occupy a fixed length bit-field of the minimum number of bits needed to encode the index. (Although it could in principle be arbitrarily large.) This is followed by the encoding of the chosen alternative, with alternatives that are extension additions encoded as if they were the value of an open type field. Where the choice has only one alternative, there is no encoding for the index.

Dummy class declaration for ASN.1 NULL type

This class implements an output stream in which the data is written into a reverse byte array. The buffer automatically grows as data is written to it. The data can be retrieved using toByteArray() and toString(). Closing a ByteArrayOutputStream has no effect. The methods in this class can be called after the stream has been closed without generating an IOException.
