Classes

  ClassDescription
AckPolicy
The AckPolicy class specifies how master and client sites will handle acknowledgment of replication messages which are necessary for "permanent" records. The current implementation requires all sites in a replication group configure the same acknowledgement policy.
ActiveTransaction
The ActiveTransaction class describes a currently active transaction.
BadSecondaryException
A secondary index has been corrupted. This is likely the result of an application operating on related databases without first associating them.
BaseCursor

The abstract base class from which all cursor classes inherit.

Cursors may span threads, but only serially, that is, the application must serialize access to the cursor handle.

BaseDatabase
The base class from which all database classes inherit

BTreeDatabase
A class representing a BTreeDatabase. The Btree format is a representation of a sorted, balanced tree structure.

DatabaseType
A class representing the supported Berkeley DB access methods.
DbThreadID
A class representing a unique identifier for a thread of control in a Berkeley DB application.
DeadlockException
When multiple threads of control are modifying the database, there is normally the potential for deadlock. In Berkeley DB, deadlock is signified by a DeadlockException thrown from the Berkeley DB function. Whenever a Berkeley DB function throws a DeadlockException, the enclosing transaction should be aborted.
DeadlockPolicy
A class to represent what lock request(s) should be rejected during deadlock resolution.
ErrorCodes
Constants representing error codes returned by the Berkeley DB library.
ForeignConflictException

JoinCursor
A class representing a join cursor, for use in performing equality or natural joins on secondary indices. For information on how to organize your data to use this functionality, see Equality join in the Programmer's Reference Guide.
KeyEmptyException
The requested key/data pair logically exists but was never explicitly created by the application, or that the requested key/data pair was deleted and never re-created. In addition, the Queue access method will throw a KeyEmptyException for records that were created as part of a transaction that was later aborted and never re-created.
KeyExistException
A key/data pair was inserted into the database using PutNoOverwrite(DatabaseEntry, DatabaseEntry) and the key already exists in the database, or using PutNoDuplicate(DatabaseEntry, DatabaseEntry) or PutNoDuplicate(DatabaseEntry, DatabaseEntry) and the key/data pair already exists in the database.
KeyRange

A class representing an estimate of the proportion of keys that are less than, equal to, and greater than a given key.

Values are in the range of 0 to 1; for example, if the field less is 0.05, 5% of the keys in the database are less than the key parameter. The value for equal will be zero if there is no matching key, and will be non-zero otherwise.

LeaseExpiredException
The site's replication master lease has expired.
LockingConfig
A class representing configuration parameters for a DatabaseEnvironment's locking subsystem.
LockingInfo
A class representing the locking options for Berkeley DB operations.
LockNotGrantedException
