/**
* A window definition.
*
* Window definitions can be
*
* - declared in the
WINDOW clause (see
* {@link SelectWindowStep#window(WindowDefinition...)}
* - referenced from the
OVER clause (see
* {@link AggregateFunction#over(WindowDefinition)}
*
*
* The WINDOW clause is only natively supported by
*
* - {@link SQLDialect#POSTGRES}
* - {@link SQLDialect#SYBASE}
*
*
* If your database supports window functions, but not the WINDOW
* clause, jOOQ will inline window definitions into their respective window
* functions.
