Class Summary

Modifier and Type	Class and Description
pack-priv class	AllocationCache An auxiliary object to cache the allocation information for a file container.

public class	AllocPage An allocation page of the file container.
public class	AllocPageOperation
pack-priv abstract class	BaseContainer BaseContainer is an abstract class that provides the locking bahaviour for an object representing an active container, that is the actual storage container, not the ContainerHandle interface.

public class	ChainAllocPageOperation
public class	CompressSpacePageOperation Log operation to implement compressing space from a container and returning it to the operating system.
public class	CompressSpacePageOperation10_2 This class overrides the CompressSpacePageOperation class to write CompressSpaceOperation Log Records that do not support negative values for new_highest_page.
pack-priv abstract class	ContainerActionOnCommit An Observer that can be attached to a transaction to implement some action when the transaction commits or rollsback in some way.
public abstract class	ContainerBasicOperation A Container Operation change the state of the container.
public abstract class	ContainerHandleActionOnCommit An abstract class that opens the container at commit and delegates the actual work to a sub-class.
public class	ContainerOperation Log operation to create, drop or remove a container.
public class	ContainerUndoOperation A Container undo operation rolls back the change of a Container operation
public class	CopyRowsOperation Represents copying num_rows from one page to another page.

public class	D_RecordId The D_RecordId class provides diagnostic information about the BaseContainerHandle class.
public class	D_StoredPage The D_StoredPage class provides diagnostic information about the StoredPage class.
public class	DecryptInputStream A DecryptInputStream is used by stream container to access an encrypted stream of bytes.
public class	DeleteOperation Represents a delete (or undelete) of a record in a page.
public class	DirectActions
public class	DirectAllocActions
public class	DropOnCommit Drop a table on a commit or abort
public class	EncryptContainerOperation Log operation to encrypt a container with a new encryption key or to encrypt an unencrypted container while configuring the database for encryption.
public class	EncryptContainerUndoOperation A Encrypt Container undo operation rolls back the change of a Encrypt Container operation
public class	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.
pack-priv abstract class	FileContainer FileContainer is an abstract base class for containers which are based on files.
public class	InitPageOperation This operation initializes the page that is being allocated, this operation does not change the alloc page information.
pack-priv class	InputStreamContainer A class that uses a ZipEntry to be a single container file, but read-only.
public class	InsertOperation Represents an insert of a record onto a page.
public class	InvalidatePageOperation Represents invalidating a page due to deallocation.
public class	LoggableActions
public class	LoggableAllocActions
pack-priv abstract class	LogicalPageOperation An abstract class that is used for logical log operation.
public class	LogicalUndoOperation LogicalUndoOperation is a compensation operation that rolls back the change of an LogicalUndoable operation.
public class	LongColumnException An exception used to pass a specfic "error code" through various layers of software.
public class	MemByteHolder A ByteHolder that stores all its bytes in memory.
pack-priv class	NoSpaceOnPage An exception used to pass a specfic "error code" through various layers of software.
public class	OverflowInputStream A OverflowInputStream is used by store to turn a long column into an InputStream.
pack-priv abstract class	PageBasicOperation A PageBasicOperation changed the content of a page, this is the root class of all page oriented operation.
pack-priv class	PageCreationArgs This class holds information that is passed to `CachedPage.createPage()` and used when a page object (either a `StoredPage` or an `AllocPage`) is created.
public class	PageVersion A per page version number is one way to implement a page time stamp
pack-priv abstract class	PhysicalPageOperation An abstract class that is used for physical log operation.
public class	PhysicalUndoOperation PhysicalUndoOperation is a compensation operation that rolls back the change of an Undo-able operation.
public class	PurgeOperation USE WITH EXTREME Caution: Purge records from a Page.
pack-priv class	RAFContainer RAFContainer (short for RandomAccessFileContainer) is a concrete subclass of FileContainer for FileContainers which are implemented on java.io.RandomAccessFile.
pack-priv class	RAFContainer4 RAFContainer4 overrides a few methods in FileContainer/RAFContainer in order to use FileChannel from Java 1.4's New IO framework to issue multiple IO operations to the same file concurrently instead of strictly serializing IO operations using a mutex on the container object.
pack-priv class	RawField
public class	ReclaimSpace Post commit work to reclaim some space from the raw store.
public class	ReclaimSpaceHelper This class helps a BaseDataFactory reclaims unused space.</nl>
public class	RecordId Implementation of RecordHandle.
public class	RememberBytesInputStream A FilterInputStream that remembers read or skipped bytes.
pack-priv class	RemoveFile
public class	RemoveFileOperation
pack-priv class	RFResource
public class	SetReservedSpaceOperation Represents shrinking of the reserved space of a particular row on a page.
public class	SpaceInformation Manage the result information from a single call to ConglomerateController.getSpaceInfo().
public class	StoredFieldHeader A class to provide static methods to manipulate fields in the field header.
public class	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.
public class	StoredRecordHeader A class StoredPage uses to cache record headers by passing instances to BasePage, and to write stored versions of record headers.
pack-priv class	StreamFileContainer The format of this stream file is: (RH) (FH) (field data) (FH) (field data) ........
pack-priv class	StreamFileContainerHandle A handle to an open stream container, implememts StreamContainerHandle.
