Method Detail

• readValue

  public abstract <T> T readValue​(JsonParser jp,
                                  Class<T> valueType)
                           throws IOException,
                                  JsonProcessingException

  Method to deserialize JSON content into a non-container type (it can be an array type, however): typically a bean, array or a wrapper type (like Boolean).

  Note: this method should NOT be used if the result type is a container (Collection or Map. The reason is that due to type erasure, key and value types can not be introspected when using this method.

  Throws:

  IOException

  JsonProcessingException

• readValue

  public abstract <T> T readValue​(JsonParser jp,
                                  TypeReference<?> valueTypeRef)
                           throws IOException,
                                  JsonProcessingException

  Method to deserialize JSON content into a Java type, reference to which is passed as argument. Type is passed using so-called "super type token" and specifically needs to be used if the root type is a parameterized (generic) container type.

  Throws:

  IOException

  JsonProcessingException

• readValue

  public abstract <T> T readValue​(JsonParser jp,
                                  JavaType valueType)
                           throws IOException,
                                  JsonProcessingException

  Method to deserialize JSON content as tree expressed using set of JsonNode instances. Returns root of the resulting tree (where root can consist of just a single node if the current event is a value event, not container).

  Throws:

  IOException

  JsonProcessingException

• readTree

  public abstract JsonNode readTree​(JsonParser jp)
                             throws IOException,
                                    JsonProcessingException

  Method to deserialize JSON content as tree expressed using set of JsonNode instances. Returns root of the resulting tree (where root can consist of just a single node if the current event is a value event, not container).

  Throws:

  IOException

  JsonProcessingException
