Method Detail

decode

public <T> T decode(InputStream stream,
                    Class<T> objectClass)
         throws Exception

Description copied from interface: IDecoder

Decode object from stream

Specified by:

decode in interface IDecoder

Overrides:

decode in class Decoder

Parameters:

stream - Input stream

objectClass - Class for object

Returns:

Created object from stream

Throws:

Exception

decodeTag

public DecodedObject decodeTag(InputStream stream)
                        throws Exception

Throws:

Exception

skipAlignedBits

protected void skipAlignedBits(InputStream stream)

decodeIntegerValueAsBytes

protected long decodeIntegerValueAsBytes(int intLen,
                                         InputStream stream)
                                  throws Exception

Throws:

Exception

decodeConstraintLengthDeterminant

protected int decodeConstraintLengthDeterminant(int min,
                                                int max,
                                                BitArrayInputStream stream)
                                         throws Exception

Decode the constraint length determinant. ITU-T X.691. 10.9. General rules for encoding a length determinant

Throws:

Exception

decodeLengthDeterminant

protected int decodeLengthDeterminant(BitArrayInputStream stream)
                               throws IOException

Decode the length determinant ITU-T X.691. 10.9. General rules for encoding a length determinant

Throws:

IOException

decodeConstraintNumber

protected long decodeConstraintNumber(long min,
                                      long max,
                                      BitArrayInputStream stream)
                               throws Exception

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.

Throws:

Exception

decodeSemiConstraintNumber

protected int decodeSemiConstraintNumber(int min,
                                         BitArrayInputStream stream)
                                  throws Exception

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.

Throws:

Exception

decodeNormallySmallNumber

protected int decodeNormallySmallNumber(BitArrayInputStream stream)
                                 throws Exception

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.

Throws:

Exception

decodeUnconstraintNumber

protected int decodeUnconstraintNumber(BitArrayInputStream stream)
                                throws Exception

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.

Throws:

Exception

decodeLength

protected int decodeLength(ElementInfo elementInfo,
