Method that may be called to check whether this deserializer provider would provide deserializer for values of given type, without attempting to construct (and possibly fail in some cases) actual deserializer. Mostly needed to support validation of polymorphic type ids. Note implementations should take care NOT to claim supporting types that they do not recognize as this could to incorrect assumption of safe support by caller. Method added in Jackson 2.13 now that Java 8 default implementations are available for use with interface definitions.

Combined into a single class to eliminate bunch of one-off implementation
classes, to reduce resulting jar size (mostly).

| public Object deserialize(JsonParser p, DeserializationContext ctxt) throws IOException Overrides com. Doc from com. 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). Note that this method is never called for JSON null literal, and thus deserializers need (and should) not check for it.
