Interface Page

All Known Implementing Classes:

PageBase

public interface Page

A page is a fixed size sequence of bytes obtained from a page manager backed by a ByteBuffer. Only the last page may have a smaller size than the others. A page does not provide its own release mechanism. Instead, the page manager returns a Reference<Page>. A page is only released iff all its references are released, hence any release action is associated with the reference. Usually the release action is performed immediately by the thread that releases the last reference.
