Examples of PageFile

org.apache.activemq.store.kahadb.disk.page.PageFile
A PageFile provides you random access to fixed sized disk pages. This object is not thread safe and therefore access to it should be externally synchronized.
The file has 3 parts: Metadata Space: 4k : Reserved metadata area. Used to store persistent config about the file. Recovery Buffer Space: Page Size * 1000 : This is a redo log used to prevent partial page writes from making the file inconsistent Page Space: The pages in the page file.
