Interface Summary
AccessFactory Module interface for an access manager.
AccessFactoryGlobals Global constants provided by the Access Interface.
BinaryOrderable The Orderable interface represents a value that can be linearly ordered.
ColumnOrdering The column ordering interface defines a column that is to be ordered in a sort or index, and how it is to be ordered.
ConglomerateController A conglomerate is an abstract storage structure (they correspond to access methods).
ConglomPropertyQueryable ConglomPropertyable provides the interfaces to read properties from a conglomerate.
DatabaseInstant A DatabaseInstant is a quantity which the database associates with events to collate them.
DynamicCompiledOpenConglomInfo Information that can be "compiled" and reused per transaction per open operation.
FileResource Management of file resources within a database.
GenericScanController The set of interfaces implemented by all types of ScanControllers.
GroupFetchScanController This scan controller can only be used for group fetch, no update operations are supported, use ScanController if you need scan interfaces other than group fetch.
Qualifier A structure which is used to "qualify" a column.
RowCountable RowCountable provides the interfaces to read and write row counts in tables.
RowLocationRetRowSource A RowLocationRetRowSource is the mechanism for iterating over a set of rows, loading those rows into a conglomerate, and returning the RowLocation of the inserted rows.
RowSource A RowSource is the mechanism for iterating over a set of rows.
ScanController A scan is the mechanism for iterating over the rows in a conglomerate, the scan controller is the interface through which access clients control the underlying scan.
ScanInfo This object provides performance information related to an open scan.
SortController A sort controller is an interface for inserting rows into a sort.
SortCostController  
SortInfo This object provides performance information related to a sort.
SortObserver A SortObserver is an object that is used as a callback by the sorter.
SpaceInfo Manage the result information from a single call to ConglomerateController.getSpaceInfo().
StaticCompiledOpenConglomInfo Information that can be "compiled" once and then used over and over again at execution time.
StoreCostController The StoreCostController interface provides methods that an access client (most likely the system optimizer) can use to get store's estimated cost of various operations on the conglomerate the StoreCostController was opened for.
StoreCostResult Manage the result information from a single call to StoreCostController.getScanCost().
TransactionController The TransactionController interface provides methods that an access client can use to control a transaction, which include the methods for gaining access to resources (conglomerates, scans, etc.) in the transaction controller's storage manager.
TransactionInfo  
XATransactionController This interface allows access to commit,prepare,abort global transactions as part of a two phase commit protocol, during runtime.
 

Class Summary
BackingStoreHashtable A BackingStoreHashtable is a utility class which will store a set of rows into an in memory hash table, or overflow the hash table to a tempory on disk structure.
GlobalXact This abstract class represents a global transaction id which can be tested for equality against other transaction ids, which can be hashed into a hash table, and which can be output as a string.
KeyHasher Provides the ability to hash on multiple objects.
RowUtil A set of static utility methods to work with rows.
