public class EnumSetDeserializer extends StdDeserializer<EnumSet<?>> implements ContextualDeserializer
EnumSets.
Note: casting within this class is all messed up -- just could not figure out a way
to properly deal with recursive definition of "EnumSet

| Modifier and Type | Method and Description |
|---|---|
JsonDeserializer<?> |
createContextual(DeserializationContext ctxt,
BeanProperty property)
Method called to see if a different (or differently configured) deserializer
is needed to deserialize values of specified property.
|
EnumSet<?> |
deserialize(JsonParser jp,
DeserializationContext ctxt)
Method that can be called to ask implementation to deserialize
JSON content into the value type this serializer handles.
|
Object |
deserializeWithType(JsonParser jp,
DeserializationContext ctxt,
TypeDeserializer typeDeserializer)
Base implementation that does not assume specific type
inclusion mechanism.
|
boolean |
isCachable()
Because of costs associated with constructing Enum resolvers,
let's cache instances by default.

null is passed instead (in which case impls usually pass 'this' deserializer as is)JsonMappingExceptionpublic EnumSet<?> deserialize(JsonParser jp, DeserializationContext ctxt) throws IOException, JsonProcessingException
JsonDeserializerPre-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. 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.
