Method Detail

init

public void init(Context context)

Description copied from class: EntityProcessor

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

firstInit

protected void firstInit(Context context)

Description copied from class: EntityProcessorBase

first time init call. do one-time operations here it's necessary to call it from the overridden method, otherwise it throws NPE on accessing zipper from nextRow()

Overrides:

firstInit in class EntityProcessorBase

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
