DatabaseNotFoundException | Thrown when an operation requires a database and that database does not exist. |
DeadlockException | DeadlockException is thrown to a thread of control when multiple threads competing for a lock are deadlocked or when a lock request would need to block and the transaction has been configured to not wait for locks. |
EnvironmentLockedException | Thrown by the Environment constructor when an environment cannot be opened for write access because another process has the same environment open for write access. |
LockNotGrantedException | A LockNotGrantedException is thrown when a non-blocking operation fails to get a lock. |
RunRecoveryException | Thrown when the JE environment has encountered an exception or a resource shortfall and cannot continue on safely. |
Foundation for creating environments, databases and transactions; provides cursor based data access.
This package provides a key/data pair model of a database record. Databases and database cursors are the key objects used to access data. An alternative collections based API is available through com.sleepycat.collections.
The Environment class embodies the database environment and is the starting point for the application. Databases and transaction objects are created through the Environment class.
Data can be inserted and retrieved directly through the Database object, or through a Cursor obtained from the Database. A database record consist of a key/data pair, where key and data are each individually represented by a DatabaseEntry object. Classes in com.sleepycat.bind provide optional support for mapping a Java object to a DatabaseEntry.
Configuration classes are used to specify the attributes of particular operations. For example the attributes of a database environment are specified in the EnvironmentConfig class. An instance of that class is required for Environment construction. Likewise, the attributes of a database are described in DatabaseConfig, which is a parameter to the Environment.openDatabase() method.
