public final Enum CBORWriteFeature

Feature that determines how binary tagged negative BigInteger values are encoded: either using CBOR standard encoding logic (as per spec), or using legacy Jackson encoding logic (encoding up to Jackson 2.19). When enabled, uses CBOR standard specified encoding of negative values (e.g., -1 is encoded [0xC3, 0x41, 0x00]). When disabled, maintains behavior of versions prior to 3.0. (e.g., -1 is encoded [0xC3, 0x41, 0x01]) and uses legacy Jackson encoding.

Note that there is the counterpart CBORReadFeature#DECODE_USING_STANDARD_NEGATIVE_BIGINT_ENCODING for encoding.

The default value is true in Jackson 3.x (was false in Jackson 2.x).

Feature that determines if an invalid surrogate encoding found in the incoming String should fail with an exception or silently be output as the Unicode 'REPLACEMENT CHARACTER' (U+FFFD) or not; if not, an exception will be thrown to indicate invalid content.

Default value is false (for backwards compatibility) meaning that an invalid surrogate will result in exception (StreamWriteException).

Feature that determines if string references are generated based on the stringref) extension. This can save storage space, parsing time, and pool string memory when parsing. Readers of the output must also support the stringref extension to properly decode the data. Extra overhead may be added to generation time and memory usage to compute the shared binary and text strings.

Default value is false meaning that the stringref extension will not be used.

Feature that determines whether generator should try to write doubles as floats: if true, will write a double as a 4-byte float if no precision loss will occur; if false, will always write a double as an 8-byte double.

Default value is false meaning that doubles will always be written as 8-byte values.

Feature that determines whether generator should try to use smallest (size-wise) integer representation: if true, will use smallest representation that is enough to retain value; if false, will use length indicated by argument type (4-byte for int, 8-byte for long and so on).

Feature that determines whether CBOR "Self-Describe Tag" (value 55799, encoded as 3-byte sequence of 0xD9, 0xD9, 0xF7) should be written at the beginning of document or not.

Default value is false meaning that type tag will not be written at the beginning of a new document.
