## Class ThrowableDeserializer

- java.lang.Object
- - org.codehaus.jackson.map.JsonDeserializer<T>
  - - org.codehaus.jackson.map.deser.std.StdDeserializer<Object>
    - - org.codehaus.jackson.map.deser.BeanDeserializer
      - - org.codehaus.jackson.map.deser.std.ThrowableDeserializer

- All Implemented Interfaces:
    ResolvableDeserializer
  Direct Known Subclasses:
    ThrowableDeserializer

      public class ThrowableDeserializer
      extends BeanDeserializer

  Deserializer that builds on basic `BeanDeserializer` but override some aspects like instance construction.

  Note that this deserializer was significantly changed in Jackson 1.7 (due to massive changes in `BeanDeserializer`).

  Since:
    1.9 (renamed from 'org.codehaus.jackson.map.deser.ThrowableDeserializer')
