## Class AbstractTypeMaterializer

- java.lang.Object
- - com.fasterxml.jackson.databind.AbstractTypeResolver
  - - com.fasterxml.jackson.module.mrbean.AbstractTypeMaterializer

- All Implemented Interfaces:
    com.fasterxml.jackson.core.Versioned

      public class AbstractTypeMaterializer
      extends com.fasterxml.jackson.databind.AbstractTypeResolver
      implements com.fasterxml.jackson.core.Versioned

  Nifty class for pulling implementations of classes out of thin air.

  ... friends call him Mister Bean... :-)
