  Parameters:

  giraphConfiguration - configuration to set.

  jsonObject - input json params

  Throws:

  ClassNotFoundException

• getTypesHolderClass

  public static Class<? extends org.apache.giraph.conf.TypesHolder> getTypesHolderClass​(org.apache.hadoop.conf.Configuration conf)

  Get a class which is parameterized by the graph types defined by user. The types holder is actually an interface that any class which holds all of Giraph types can implement. It is used with reflection to infer the Giraph types.

  The current order of type holders we try are: 1) The TypesHolder class directly. 2) The Computation class, as that holds all the types.

  Parameters:

  conf - Configuration

  Returns:

  TypesHolder or null if could not find one.

• parseJavaFragment

                                       IFragment fragment)

  For input IFragment, we check parse the type arguments, and set to giraphConfiguration.

  Parameters:

  giraphConfiguration - configuration to set.

  fragment - IFragment obj.
