Description

Interface Summary

BtreePrefixCalculator	An interface specifying how Btree prefixes should be calculated.
ErrorHandler	An interface specifying a callback function to be called when an error occurs in the Berkeley DB library.
FeedbackHandler	An interface specifying a function to be called to provide feedback.
Hasher	An application-specified, database hash function.
LogRecordHandler	A function to process application-specific log records.
MessageHandler	An interface specifying a callback function to be called to display informational messages.
PanicHandler	An interface specifying a function to be called if the database environment panics.
RecordNumberAppender	An interface specifying a callback function that modifies stored data based on a generated key.
ReplicationTransport	An interface specifying a replication transmit function, which sends information to other members of the replication group.
SecondaryKeyCreator	An interface specifying how secondary keys for a SecondaryDatabase are created.

Class Summary

BtreeStats	The BtreeStats object is used to return Btree or Recno database statistics.
CacheFile	This class allows applications to modify settings for a Database using the Database.getCacheFile.
CacheFilePriority	Priorities that can be assigned to files in the cache.
CacheFileStats	Statistics for a file in the cache.
CacheStats	Cache statistics for a database environment.
CheckpointConfig	Specifies the attributes of an application invoked checkpoint operation.
Cursor	A database cursor.
CursorConfig	Specify the attributes of database cursor.
Database	A database handle.
DatabaseConfig	Specify the attributes of a database.
DatabaseEntry	Encodes database key and data items as a byte array.
DatabaseStats	Statistics for a single database.
DatabaseType	Database types.
Environment	A database environment.
EnvironmentConfig	Specifies the attributes of an environment.
HashStats	The HashStats object is used to return Hash database statistics.
JoinConfig	The configuration properties of a JoinCursor.
JoinCursor	A specialized join cursor for use in performing equality or natural joins on secondary indices.
KeyRange	An object that returns status from the Database.getKeyRange method.
Lock	The locking interfaces for the database environment are methods of the Environment handle.
LockDetectMode	Deadlock detection modes.
LockMode	Locking modes for database operations.
LockOperation	Operations that can be performed on locks.
LockRequest	The LockRequest object is used to encapsulate a single lock request.
LockRequestMode	When using the default lock conflict matrix, the LockRequestMode class defines the set of possible lock modes.
LockStats	Lock statistics for a database environment.
LogCursor	The LogCursor object is the handle for a cursor into the log files, supporting sequential access to the records stored in log files.
LogSequenceNumber	The LogSequenceNumber object is a log sequence number which specifies a unique location in a log file.
LogStats	Log statistics for a database environment.
MultipleDataEntry	A DatabaseEntry that holds multiple data items returned by a single Database or Cursor get call.
MultipleEntry	An abstract class representing a DatabaseEntry that holds multiple results returned by a single Cursor get method.
MultipleKeyDataEntry	A DatabaseEntry that holds multiple key/data pairs returned by a single Database or Cursor get call.
MultipleRecnoDataEntry	A DatabaseEntry that holds multiple record number/data pairs returned by a single Database or Cursor get call.
OperationStatus	Status values from database operations.
PreparedTransaction	The PreparedTransaction object is used to encapsulate a single prepared, but not yet resolved, transaction.
QueueStats	The QueueStats object is used to return Queue database statistics.
RecoveryOperation	The recovery operation being performed when LogRecordHandler.handleLogRecord is called.
ReplicationStats	Replication statistics for a database environment.
ReplicationStatus	The return status from processing a replication message.
SecondaryConfig	The configuration properties of a SecondaryDatabase extend those of a primary Database.
SecondaryCursor	A database cursor for a secondary database.
SecondaryDatabase	A secondary database handle.
Sequence	A Sequence handle is used to manipulate a sequence record in a database.
SequenceConfig	Specify the attributes of a sequence.
SequenceStats	A SequenceStats object is used to return sequenece statistics.
StatsConfig	Specifies the attributes of a statistics retrieval operation.
Transaction	The Transaction object is the handle for a transaction.
TransactionConfig	Specifies the attributes of a database environment transaction.
TransactionStats	Transaction statistics for a database environment.
VerifyConfig	Specifies the attributes of a verification operation.

Exception Summary

DatabaseException	The root of all database exceptions.
DeadlockException	DeadlockException is thrown to a thread of control when multiple threads competing for a lock are deadlocked, when a lock request has timed out or when a lock request would need to block and the transaction has been configured to not wait for locks.
LockNotGrantedException	A LockNotGrantedException is thrown when a lock requested using the Environment.getLock or Environment.lockVector methods, where the noWait flag or lock timers were configured, could not be granted before the wait-time expired.
MemoryException	This exception is thrown when a DatabaseEntry passed to a Database or Cursor method is not large enough to hold a value being returned.
ReplicationHandleDeadException	Thrown when a database handle has been invalidated because a replication election unrolled a committed transaction.
RunRecoveryException	Thrown when the database environment needs to be recovered.

Package com.sleepycat.db Description

Berkeley DB Java API
[reference guide] [Java programming notes].

This package is a wrapper around the Berkeley DB library. It uses JNI to provide access to Berkeley DB, which is implemented in C. That means that a shared library or DLL must be available when applications use this package.

There are also several utilities provided with Berkeley DB that make administrative tasks possible from the command line. For more information, see the page Berkeley DB Supporting Utilities.
