This type is used for the window function DSL API.

Example: 
field.firstValue()
     .ignoreNulls()
     .over()
     .partitionBy(AUTHOR_ID)
     .orderBy(PUBLISHED_IN.asc())
     .rowsBetweenUnboundedPreceding()
     .andUnboundedFollowing()

 Unlike in WindowBeforeOverStep, OVER() is a mandatory
clause.
