Compare Field

BerkeleyDB

The Secondary Hash key comparison function.

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

Syntax

C#
public EntryComparisonDelegate Compare
Visual Basic (Declaration)
Public Compare As EntryComparisonDelegate
Visual C++
public:
EntryComparisonDelegate^ Compare

Remarks

The comparison function is called whenever it is necessary to compare a key specified by the application with a key currently stored in the tree.

If no comparison function is specified, the keys are compared lexically, with shorter keys collating before longer keys.

If the database already exists, the comparison function must be the same as that historically used to create the database or corruption can occur.
