_isLenient
protected final boolean _isLenientFlag that indicates what leniency setting is enabled for this deserializer (either dueJsonFormat.Shapeannotation 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.- Since:
- 2.11

deserialize
public LocalDateTime deserialize(JsonParser parser, DeserializationContext context) throws IOException Description copied from class:JsonDeserializerMethod 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 JSONnullliteral to avoid every deserializer from having to handle null values. Instead, theJsonDeserializer.getNullValue(DeserializationContext)method is called to produce a null value. To influence null handling, custom deserializers should overrideJsonDeserializer.getNullValue(DeserializationContext)and usually alsoJsonDeserializer.getNullAccessPattern().- Specified by:
deserializein classJsonDeserializer<LocalDateTime>- Parameters:
parser- Parser used for reading JSON contentcontext- Context that can be used to access information about this deserialization activity.- Returns:
- Deserialized value

logicalType
Description copied from class:JsonDeserializerMethod for accessing logical type of values this deserializer produces. Typically used for further configuring handling of values, for example, to find which coercions are legal.- Overrides:

deserializeWithType
