From 39464a990ff8bdc9a8560469641dec04c13eefe7 Mon Sep 17 00:00:00 2001 From: fyrz Date: Tue, 28 Oct 2014 22:38:08 +0100 Subject: [PATCH] [RocksJava] Options Refactoring 3.6 Summary: Options extends now two interfaces DBOptionsInterface and ColumnFamilyOptionsInterface. There are also further improvements to the Options bindings: Optimize methods were ported to Java. (OptimizeForPointLookup, OptimizeLevelCompaction, OptimizeUniversalCompaction). To align BuiltinComparator with every other Enum it was moved to a separate file.
