cache2prst_read

public <R> R cache2prst_read(Function<IntArrayReadOnly,R> code)

Description copied from interface: CachePagedState

Отображение кеша страниц на основную память.

Семантика: cache2prst[ cache_page_index ] = hard_pages_index

Значение (hard_pages_index):

• -1 или меньше - нет отображения
• 0 или больше - отображение есть

  страница может быть чистой или грязной: DirtyPagedDataBase.dirty(int) - где аргумент hard_pages_index

Specified by:
