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. 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.

Specified by:

deserialize in class JsonDeserializer<java.lang.Enum<?>>

Parameters:

jp - Parsed used for reading Json content

ctxt - Context that can be used to access information about this deserialization activity.

Returns:

Deserializer value

Throws:

java.io.IOException

JsonProcessingException
