- All Implemented Interfaces:
ObjectCodec<short[]>
,ObjectDecoder<short[]>

Method Details

encodeAndGet
Encode the input array into the internal buffer and return it.- Parameters:
input
- the array to encode- Returns:
- a reference to the internal byte buffer
-
maybeGetResizedBuffer
@NotNull public static ByteBuffer maybeGetResizedBuffer(@Nullable short[] input, @Nullable ByteBuffer origBuffer) Inspect the input buffer. If it is large enough to encode input, clear and return it, otherwise allocate a new buffer with an appropriate capacity and return that.- Parameters:
input
- the input to encodeorigBuffer
- the original buffer to maybe resize.- Returns:
- a properly sized byte buffer to encode input.
-
encodeInto
Encode the input values to the specified buffer.- Parameters:
input
- the input, may be null.byteBuffer
- the buffer to encode into
-
decode
Decode a short array from the inputByteBuffer
- Parameters:
byteBuffer
- the buffer containing the encoded short array- Returns:
- the decoded short array
-

encode
@NotNull public byte[] encode(@Nullable short[] input) Description copied from interface:ObjectCodec
Encode the specified input as an array of bytes. Note that it is up to the implementation how to encode null inputs. The use of a zero-length byte array (e.g.CollectionUtil.ZERO_LENGTH_BYTE_ARRAY
) is strongly encouraged.- Specified by:
encode
in interfaceObjectCodec<short[]>
- Parameters:
input
- The input object, possibly null- Returns:
- The output byte array
-
isNullable
public boolean isNullable()Description copied from interface:ObjectCodec
Does this codec support encoding of null values?- Specified by:
isNullable
in interfaceObjectCodec<short[]>
- Returns:
- if null values are supported
-
getPrecision
public int getPrecision()Description copied from interface:ObjectCodec
If applicable, the maximum encodable precision. If precision is not applicable (i.e. for non-numeric types) this method should return zero.- Specified by:
getPrecision
in interfaceObjectCodec<short[]>
- Returns:
- the numeric precision supported by this codec
-
getScale
public int getScale()Description copied from interface:ObjectCodec
If applicable, the maximum encodable scale. If scale is not applicable (i.e. for non-numeric types) this method should return zero.- Specified by:
getScale
in interfaceObjectCodec<short[]>
- Returns:
- the numeric scale (digits after the decimal point) supported by this codec
-
decode
@Nullable public short[] decode(@NotNull byte[] input, int offset, int length) Description copied from interface:ObjectDecoder
Decode an object from an array of bytes.- Specified by:
decode
in interfaceObjectDecoder<short[]>
- Parameters:
input
- The input byte array containing bytes to decodeoffset
- The offset into the byte array to start decoding fromlength
- The length of the byte array to decode from, starting at the offset- Returns:
- The output object, possibly null
-
expectedObjectWidth
public int expectedObjectWidth()Description copied from interface:ObjectDecoder
What width byte array does this ObjectCodec expect to encode and decode?- Specified by:
expectedObjectWidth
in interfaceObjectDecoder<short[]>
- Returns:
- VARIABLE_WIDTH_SENTINEL if the codec must encode and decode variable width columns, otherwise the fixed size of byte array that must be decoded and encoded.
