Flag set from JavaTimeFeature.ALWAYS_ALLOW_STRINGIFIED_DATE_TIMESTAMPS to determine whether stringified numbers are interpreted as timestamps (enabled) nor not (disabled) in addition to a custom pattern ({code DateTimeFormatter}).

_isLenient

protected final boolean _isLenient

Flag that indicates what leniency setting is enabled for this deserializer (either due JsonFormat.Shape annotation on property or class, or due to per-type "config override", or from global settings): leniency/strictness has effect on accepting some non-default input value representations (such as integer values for dates).

Note that global default setting is for leniency to be enabled, for Jackson 2.x, and has to be explicitly change to force strict handling: this is to keep backwards compatibility with earlier versions.

Note that with 2.12 and later coercion settings are moving to CoercionConfig, instead of simple yes/no leniency setting.

deserialize

public T deserialize(JsonParser parser,
 DeserializationContext context)
              throws IOException

Description copied from class: JsonDeserializer

Method that can be called to ask implementation to deserialize JSON content into the value type this serializer handles. Returned instance is to be constructed by method itself.

Pre-condition for this method is that the parser points to the first event that is part of value to deserializer (and which is never JSON 'null' literal, more on this below): for simple types it may be the only value; and for structured types the Object start marker or a FIELD_NAME.

The two possible input conditions for structured types result from polymorphism via fields. In the ordinary case, Jackson calls this method when it has encountered an OBJECT_START, and the method implementation must advance to the next token to see the first field name. If the application configures polymorphism via a field, then the object looks like the following.

      {
          "@class": "class name",
          ...
      }
  

Jackson consumes the two tokens (the @class field name and its value) in order to learn the class and select the deserializer. Thus, the stream is pointing to the FIELD_NAME for the first field after the @class. Thus, if you want your method to work correctly both with and without polymorphism, you must begin your method with:

       if (p.currentToken() == JsonToken.START_OBJECT) {
         p.nextToken();
       }
  

This results in the stream pointing to the field name, so that the two conditions align.

Post-condition is that the parser will point to the last event that is part of deserialized value (or in case deserialization fails, event that was not recognized or usable, which may be the same event as the one it pointed to upon call).

Handling null values (JsonToken.VALUE_NULL)
: Note that this method is never called for the JSON null literal to avoid every deserializer from having to handle null values. Instead, the JsonDeserializer.getNullValue(DeserializationContext) method is called to produce a null value. To influence null handling, custom deserializers should override JsonDeserializer.getNullValue(DeserializationContext) and usually also JsonDeserializer.getNullAccessPattern().

Specified by:

parser - Parser used for reading JSON content
