LMDBFlagSet class - lmdb library

LMDBFlagSet class

A class for managing LMDB flag combinations in a type-safe way.

This class provides methods to combine, check and manipulate LMDB flags that control various aspects of database behavior. It handles the bitwise operations internally and provides a clean interface for Dart code.

Example:

// Create a custom flag set
final flags = LMDBFlagSet()
  ..add(MDB_NOSUBDIR)
  ..add(MDB_NOSYNC);

// Or use predefined combinations
final readOnlyFlags = LMDBFlagSet.readOnly;

Constructors

LMDBFlagSet(): Creates an empty flag set with no flags set.
LMDBFlagSet.fromFlags(int _flags): Creates a flag set initialized with the provided flags value.
