Examples of org.hornetq.core.paging.impl.PagingStoreImpl.depage()

org.hornetq.core.paging.impl.PagingStoreImpl.depage()
It returns a Page out of the Page System without reading it. The method calling this method will remove the page and will start reading it outside of any locks. This method could also replace the current file by a new file, and that process is done through acquiring a writeLock on currentPageLock Observation: This method is used internally as part of the regular depage process, but externally is used only on tests, and that's why this method is part of the Testable Interface
