|---|---|
void |
acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor,
JavaType typeHint)
Default implementation specifies no format.
|
JsonNode |
getSchema(SerializerProvider provider,
Type typeHint)
Default implementation simply claims type is "string"; usually
overriden by custom serializers.
|
void |
serialize(Object value,
com.fasterxml.jackson.core.JsonGenerator gen,
SerializerProvider provider)
Method that can be called to ask implementation to serialize
values of type this serializer handles.
|
void |
serializeWithType(Object value,
com.fasterxml.jackson.core.JsonGenerator gen,
SerializerProvider serializers,
TypeSerializer typeSer)
Although this method should rarely get called, for convenience we should override
it, and handle it same way as "natural" types: by serializing exactly as is,
without type decorations.
