com.fasterxml.jackson.core.JsonProcessingException

Specified by:

deserialize in class com.fasterxml.jackson.databind.JsonDeserializer<Object>

Throws:

IOException

com.fasterxml.jackson.core.JsonProcessingException

deserializeWithType

public Object deserializeWithType(com.fasterxml.jackson.core.JsonParser jp,
 com.fasterxml.jackson.databind.DeserializationContext ctxt,
 com.fasterxml.jackson.databind.jsontype.TypeDeserializer typeDeserializer)
                           throws IOException
