public interface WindowBeforeOverStep<T> extends WindowOverStep<T>, Field<T>
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 WindowOverStep, OVER() is an optional clause clause.
