Class ByteBufferProxy

java.lang.Object

org.lmdbjava.ByteBufferProxy

public final class ByteBufferProxy
extends Object

ByteBuffer-based proxy.

There are two concrete ByteBuffer proxy implementations available:

• A "fast" implementation: ByteBufferProxy.UnsafeProxy
• A "safe" implementation: ByteBufferProxy.ReflectiveProxy

Users nominate which implementation they prefer by referencing the PROXY_OPTIMAL or PROXY_SAFE field when invoking Env.create(org.lmdbjava.BufferProxy).

Field Details

PROXY_OPTIMAL

public static final BufferProxy<ByteBuffer> PROXY_OPTIMAL

The fastest ByteBuffer proxy that is available on this platform. This will always be the same instance as PROXY_SAFE if the UnsafeAccess.DISABLE_UNSAFE_PROP has been set to true and/or UnsafeAccess is unavailable. Guaranteed to never be null.

PROXY_SAFE

public static final BufferProxy<ByteBuffer> PROXY_SAFE

The safe, reflective ByteBuffer proxy for this system. Guaranteed to never be null.
