MoveNextUnique Method (LockingInfo)

BerkeleyDB

previous page next page

If the cursor is not yet initialized, MoveNextUnique is identical to MoveFirst()()(). Otherwise, move the cursor to the next non-duplicate key in the database, and store the secondary key and primary key/data pair in Current. MoveNextUnique will return false if no non-duplicate key/data pairs exist after the cursor position in the database.

Namespace: BerkeleyDB
Assembly: libdb_dotnet48 (in libdb_dotnet48.dll) Version: 4.8.24.0

Syntax

C#
public bool MoveNextUnique( LockingInfo info )

Visual Basic (Declaration)
Public Function MoveNextUnique ( _ info As LockingInfo _ ) As Boolean

Visual C++
public: bool MoveNextUnique( LockingInfo^ info )

Parameters

info: Type: BerkeleyDB..::.LockingInfo
The locking behavior to use.

Return Value

True if the cursor was positioned successfully, false otherwise.

Remarks

If the database is a Queue or Recno database, MoveNextUnique will ignore any keys that exist but were never explicitly created by the application, or those that were created and later deleted.

If positioning the cursor fails, Current will contain an empty KeyValuePair<(Of <(TKey, TValue>)>).
