java.lang.Objectcom.fasterxml.jackson.databind.deser.DataFormatReaders
public class DataFormatReaders
Alternative to DataFormatDetector that needs to be used when
using data-binding.
| Nested Class Summary | |
|---|---|
protected class |
DataFormatReaders.AccessorForReader
We need sub-class here as well, to be able to access efficiently. |
static class |
DataFormatReaders.Match
Result class, similar to DataFormatMatcher |
| Field Summary | |
|---|---|
protected int |
_maxInputLookahead
Maximum number of leading bytes of the input that we can read to determine data format. |
protected MatchStrength |
_minimalMatch
Strength of minimal match we accept as the answer, unless better matches are found. |
protected MatchStrength |
_optimalMatch
Strength of match we consider to be good enough to be used without checking any other formats. |
protected ObjectReader[] |
_readers
Ordered list of readers which both represent data formats to detect (in precedence order, starting with highest) and contain factories used for actual detection. |
static int |
DEFAULT_MAX_INPUT_LOOKAHEAD
By default we will look ahead at most 64 bytes; in most cases, much less (4 bytes or so) is needed, but we will allow bit more leniency to support data formats that need more complex heuristics. |
