Parameters
- key
- Type: BerkeleyDB..::.DatabaseEntry
The key to search for
- data
- Type: BerkeleyDB..::.DatabaseEntry
The data to search for
- BufferSize
- Type: System..::.Int32
The initial size of the buffer to fill with duplicate data items. If the buffer is not large enough, it will be automatically resized.
- txn
- Type: BerkeleyDB..::.Transaction
txn is a Transaction object returned from BeginTransaction()()(); if the operation is part of a Berkeley DB Concurrent Data Store group, txn is a handle returned from BeginCDSGroup()()(); otherwise null.
- info
- Type: BerkeleyDB..::.LockingInfo
The locking behavior to use.
Return Value
A KeyValuePair<(Of <(TKey, TValue>)>) whose Key parameter is key and whose Value parameter is the retrieved data items.Exceptions
Exception | Condition |
---|---|
BerkeleyDB..::.NotFoundException | A NotFoundException is thrown if key and data are not in the database. |
BerkeleyDB..::.KeyEmptyException | A KeyEmptyException is thrown if the database is a QueueDatabase or RecnoDatabase database and key exists, but was never explicitly created by the application or was later deleted. |
