This method is called when it starts processing an entity. When it comes back to the entity it is called again. So it can reset anything at that point. For a rootmost entity this is called only once for an ingestion. For sub-entities , this is called multiple once for each row from its parent entity

Overrides:

init in class EntityProcessorBase

Parameters:

context - The current context

nextRow

public Map<String,Object> nextRow()

Description copied from class: EntityProcessorBase

For a simple implementation, this is the only method that the sub-class should implement. This is intended to stream rows one-by-one. Return null to signal end of rows

Overrides:

nextRow in class EntityProcessorBase

Returns:

a row where the key is the name of the field and value can be any Object or a Collection of objects. Return null to signal end of rows
