All known Subclasses: org.apache.derby.impl.store.raw.data.TempRAFContainer,
| RAFContainer | | class RAFContainer extends FileContainer implements PrivilegedExceptionAction(Code) | | RAFContainer (short for RandomAccessFileContainer) is a concrete subclass of FileContainer
for FileContainers which are implemented on java.io.RandomAccessFile.
|
| Method Summary | |
| protected void | backupContainer(BaseContainerHandle handle, String backupLocation)
Backup the container.
Parameters:
handle - the container handle.
Parameters:
backupLocation - location of the backup container. | | public void | clean(boolean forRemove)
Clean the container.
Write out the container header and sync all dirty pages of this
container to disk before returning.
checkpoint calls this interface through callbacks by telling
the cache manager to clean all containers in the open container
cache. | | final void | closeContainer()
| | synchronized void | createContainer(ContainerKey newIdentity)
| | public Cacheable | createIdentity(Object key, Object createParameter)
| | protected void | encryptContainer(BaseContainerHandle handle, String newFilePath)
Create encrypted version of the container with the
user specified encryption properties. | | protected void | flushAll()
| | synchronized StorageFile | getFileName(ContainerKey identity, boolean stub, boolean errorOK, boolean tryAlternatePath)
| | public synchronized boolean | isDirty()
| | synchronized boolean | openContainer(ContainerKey newIdentity)
| | protected int | preAllocate(long lastPreallocPagenum, int preAllocSize)
| | protected StorageFile | privGetFileName(ContainerKey identity, boolean stub, boolean errorOK, boolean tryAlternatePath)
| | synchronized StorageRandomAccessFile | privGetRandomAccessFile(StorageFile file)
| | protected void | readPage(long pageNumber, byte[] pageData)
Read a page into the supplied array. | | protected void | removeContainer(LogInstant instant, boolean leaveStub)
| | synchronized boolean | removeFile(StorageFile file)
| | public Object | run()
| | public Cacheable | setIdentity(Object key)
| | protected void | truncatePages(long lastValidPagenum)
Truncate pages of a container.
Truncate all pages from lastValidPagenum+1 through the end of the file.
Parameters:
lastValidPagenum - The page number of the last valid page of thefile. | | protected void | writePage(long pageNumber, byte[] pageData, boolean syncPage)
Write a page from the supplied array. |
| needsSync | | protected boolean needsSync(Code) | | |
| clean | | public void clean(boolean forRemove) throws StandardException(Code) | | Clean the container.
Write out the container header and sync all dirty pages of this
container to disk before returning.
checkpoint calls this interface through callbacks by telling
the cache manager to clean all containers in the open container
cache. This sync of the file happens as part of writing and then
syncing the container header in writeRAFHeader().
Parameters:
forRemove - Is clean called because container is being removed?
exception:
StandardException - Standard exception policy. |
| closeContainer | | final void closeContainer()(Code) | | |
| encryptContainer | | protected void encryptContainer(BaseContainerHandle handle, String newFilePath) throws StandardException(Code) | | Create encrypted version of the container with the
user specified encryption properties.
Read all the pages of the container from the original container
through the page cache, encrypt each page data with new encryption
mechanism and write to the specified container file.
Parameters:
handle - the container handle.
Parameters:
newFilePath - file to store the new encrypted version of the container
exception:
StandardException - Derby Standard error policy |
| isDirty | | public synchronized boolean isDirty()(Code) | | |
| preAllocate | | protected int preAllocate(long lastPreallocPagenum, int preAllocSize)(Code) | | Preallocate some pages if need be
|
| truncatePages | | protected void truncatePages(long lastValidPagenum) throws StandardException(Code) | | Truncate pages of a container.
Truncate all pages from lastValidPagenum+1 through the end of the file.
Parameters:
lastValidPagenum - The page number of the last valid page of thefile. All pages after this one are truncated.
exception:
StandardException - Standard exception policy. |
