Package Samples:

• org.apache.derby.impl.store.access.conglomerate

Classes:

• GenericScanController: Generic class implementing shared ScanController methods. Logically a scancontroller is used to scan a set of rows that meet some specified qualification. Rows that meet the qualification may be operated upon by the scan to fetch, delete, or replace. The ScanController also supports the notion or "repositioning" the scan, which simply resets the beginning of the scan to a new place, and allows the user to continue from there. This class attempts to abstract out some of the parts of the scan such that maybe multiple access methods can share code, even if they perform parts of the scan wildly differently. ...
• OpenConglomerate: A Generic class which implements the basic functionality needed to operate on an "open" conglomerate. This class assumes the following general things about the access method. The access method is page based and contained in a single container maintained by raw store.
• ConglomerateUtil: Static utility routine package for all Conglomerates. A collection of static utility routines that are shared by multiple Conglomerate implementations.
• BinaryOrderableWrapper: The BinaryOrderableWrapper is a wrapper class which intercepts the readExternal() callback made by raw store during a fetch, and does a comparison instead.
• GenericConglomerate: A class that implements the methods shared across all implementations of the Conglomerate interface.
• RowPosition: Just an easy way to pass information back and forth about current position of a row in a table.
• OpenConglomerateScratchSpace: A utility class to store and use temporary scratch space associated with a conglomerate.
• GenericCostController: A Generic class which implements the basic functionality needed for a cost controller.
