PageActions

Class Summary

Class	Description
AllocExtent	An allocation extent row manages the page status of page in the extent.
AllocPage	An allocation page of the file container.
AllocPageOperation
BaseContainerHandle	A handle to an open container, implememts RawContainerHandle.
BaseDataFileFactory	Provides the abstract class with most of the implementation of DataFactory and ModuleControl shared by all the different filesystem implementations.
BaseDataFileFactoryJ4	This class overloads BaseDataFileFactory to produce RAFContainer4 objects instead of RAFContainer objects.
BufferedByteHolderInputStream
ByteHolderInputStream
CachedPage	A base page that is cached.
ChainAllocPageOperation
CompressSpacePageOperation	Log operation to implement compressing space from a container and returning it to the operating system.
CompressSpacePageOperation10_2	This class overrides the CompressSpacePageOperation class to write CompressSpaceOperation Log Records that do not support negative values for new_highest_page.
ContainerBasicOperation	A Container Operation change the state of the container.
ContainerHandleActionOnCommit	An abstract class that opens the container at commit and delegates the actual work to a sub-class.
ContainerOperation	Log operation to create, drop or remove a container.
ContainerUndoOperation	A Container undo operation rolls back the change of a Container operation
CopyRowsOperation	Represents copying num_rows from one page to another page.
D_BaseContainerHandle	The D_BaseContainerHandle class provides diagnostic information about the BaseContainerHandle class.
D_DiagnosticUtil	This class provides some utility functions used to debug on disk structures of the store.
D_RecordId	The D_RecordId class provides diagnostic information about the BaseContainerHandle class.
D_StoredPage	The D_StoredPage class provides diagnostic information about the StoredPage class.
DecryptInputStream	A DecryptInputStream is used by stream container to access an encrypted stream of bytes.
DeleteOperation	Represents a delete (or undelete) of a record in a page.
DirectActions
DirectAllocActions
DropOnCommit	Drop a table on a commit or abort
EncryptContainerOperation	Log operation to encrypt a container with a new encryption key or to encrypt an unencrypted container while configuring the database for encryption.
EncryptContainerUndoOperation	A Encrypt Container undo operation rolls back the change of a Encrypt Container operation
EncryptOrDecryptData	This class is used to encrypt all the containers in the data segment with a new encryption key when password/key is changed or when an existing database is reconfigured for encryption.
InitPageOperation	This operation initializes the page that is being allocated, this operation does not change the alloc page information.
InsertOperation	Represents an insert of a record onto a page.
InvalidatePageOperation	Represents invalidating a page due to deallocation.
LoggableActions
LoggableAllocActions
LogicalUndoOperation	LogicalUndoOperation is a compensation operation that rolls back the change of an LogicalUndoable operation.
MemByteHolder	A ByteHolder that stores all its bytes in memory.
OverflowInputStream	A OverflowInputStream is used by store to turn a long column into an InputStream.
PageVersion	A per page version number is one way to implement a page time stamp
PhysicalUndoOperation	PhysicalUndoOperation is a compensation operation that rolls back the change of an Undo-able operation.
PurgeOperation	USE WITH EXTREME Caution: Purge records from a Page.
ReclaimSpace	Post commit work to reclaim some space from the raw store.
ReclaimSpaceHelper	This class helps a BaseDataFactory reclaims unused space.
RecordId	Implementation of RecordHandle.
RememberBytesInputStream	A FilterInputStream that remembers read or skipped bytes.
RemoveFileOperation
SetReservedSpaceOperation	Represents shrinking of the reserved space of a particular row on a page.
SpaceInformation	Manage the result information from a single call to ConglomerateController.getSpaceInfo().
StoredFieldHeader	A class to provide static methods to manipulate fields in the field header.
StoredPage	StoredPage is a sub class of CachedPage that stores page data in a fixed size byte array and is designed to be written out to a file through a DataInput/DataOutput interface.
StoredRecordHeader	A class StoredPage uses to cache record headers by passing instances to BasePage, and to write stored versions of record headers.
SyncOnCommit	Flush all pages for a table on a commit
TruncateOnCommit	Truncate a temp table on a commit, abort or rollback to savepoint
UpdateFieldOperation	Represents the update of a particular field of a row on a page.
UpdateOperation	Represents the update of a particular row on a page.

Exception Summary

Exception	Description
LongColumnException	An exception used to pass a specfic "error code" through various layers of software.
