import org.jooq.impl.DSL;

A window specification.

Window specifications are the syntactic clauses that can be passed to both
window definitions in WINDOW clauses, as well as to the
OVER clause of window functions. This makes window
specifications highly reusable across several queries.

Example: 
WindowSpecification spec =
DSL.partitionBy(BOOK.AUTHOR_ID)
   .orderBy(BOOK.ID)
   .rowsBetweenUnboundedPreceding()
   .andCurrentRow();

 Instances can be created using DSL.partitionBy(Field<?>...), DSL.orderBy(OrderField<?>...), and overloads as well as rows / range / groups related methods in DSL.
