Method Detail

• getValueClass

  public Class<?> getValueClass()

  Description copied from class: ValueInstantiator
  Accessor for raw (type-erased) type of instances to create.

  NOTE: since this method has not existed since beginning of Jackson 2.0 series, default implementation will just return Object.class; implementations are expected to override it with real value.

  Overrides:

  getValueClass in class ValueInstantiator

• canInstantiate

  public boolean canInstantiate()

  Description copied from class: ValueInstantiator
  Method that will return true if any of canCreateXxx method returns true: that is, if there is any way that an instance could be created.

  Overrides:

  canInstantiate in class ValueInstantiator

• canCreateUsingDefault

  public boolean canCreateUsingDefault()

  Description copied from class: ValueInstantiator
  Method that can be called to check whether a default creator (constructor, or no-arg static factory method) is available for this instantiator

  Overrides:

  canCreateUsingDefault in class ValueInstantiator

• createUsingDefault

  public Object createUsingDefault(DeserializationContext ctxt)
                            throws IOException

  Description copied from class: ValueInstantiator
  Method called to create value instance from a JSON value when no data needs to passed to creator (constructor, factory method); typically this will call the default constructor of the value object. It will only be used if more specific creator methods are not applicable; hence "default".

  This method is called if ValueInstantiator.getFromObjectArguments(com.fasterxml.jackson.databind.DeserializationConfig) returns null or empty List.

  Overrides:

  createUsingDefault in class ValueInstantiator

  Throws:

  IOException
