      Overridable fluent factory method used for creating contextual instances.

    • createContextual

      public com.fasterxml.jackson.databind.JsonDeserializer<?> createContextual(com.fasterxml.jackson.databind.DeserializationContext ctxt, com.fasterxml.jackson.databind.BeanProperty property) throws com.fasterxml.jackson.databind.JsonMappingException
      Method called to finalize setup of this deserializer, after deserializer itself has been registered. This is needed to handle recursive and transitive dependencies.
      Specified by:
      createContextual in interface com.fasterxml.jackson.databind.deser.ContextualDeserializer
      Throws:
      com.fasterxml.jackson.databind.JsonMappingException

    • deserializeWithType

      public Object deserializeWithType(com.fasterxml.jackson.core.JsonParser p, com.fasterxml.jackson.databind.DeserializationContext ctxt, com.fasterxml.jackson.databind.jsontype.TypeDeserializer typeDeserializer) throws IOException
      Base implementation that does not assume specific type inclusion mechanism. Sub-classes are expected to override this method if they are to handle type information.
      Overrides:
      deserializeWithType in class com.fasterxml.jackson.databind.JsonDeserializer<T extends org.pcollections.PMap<Object,Object>>
      Throws:
      IOException

    • deserialize

      public T deserialize(com.fasterxml.jackson.core.JsonParser p, com.fasterxml.jackson.databind.DeserializationContext ctxt) throws IOException

    • createEmptyMap

      protected abstract T createEmptyMap()

    • _deserializeEntries

      protected T _deserializeEntries(com.fasterxml.jackson.core.JsonParser p, com.fasterxml.jackson.databind.DeserializationContext ctxt) throws IOException
      Throws:

    • _handleNull

      protected T _handleNull(com.fasterxml.jackson.databind.DeserializationContext ctxt, Object key, com.fasterxml.jackson.databind.JsonDeserializer<?> valueDeser, T map) throws IOException
      Overridable helper method called when a JSON null value is encountered. Since PCollections Maps typically do not allow null values, special handling is needed; default is to simply ignore and skip such values, but alternative could be to throw an exception.
      Throws:
      IOException
