trait ByteBufferSerializer extends AnyRef
Serializer between an object and a ByteBuffer
representing that object.
Implementations should typically extend SerializerWithStringManifest and
in addition to the ByteBuffer
based toBinary
and fromBinary
methods also
implement the array based toBinary
and fromBinary
methods. The array based
methods will be used when ByteBuffer
is not used, e.g. in Akka Persistence.
Note that the array based methods can for example be implemented by delegation like this:
// you need to know the maximum size in bytes of the serialized messages val pool = new akka.io.DirectByteBufferPool(defaultBufferSize = 1024 * 1024, maxPoolEntries = 10) // Implement this method for compatibility with `SerializerWithStringManifest`. override def toBinary(o: AnyRef): Array[Byte] = { val buf = pool.acquire() try { toBinary(o, buf) buf.flip() val bytes = new Array[Byte](buf.remaining) buf.get(bytes) bytes } finally { pool.release(buf) } } // Implement this method for compatibility with `SerializerWithStringManifest`. override def fromBinary(bytes: Array[Byte], manifest: String): AnyRef = fromBinary(ByteBuffer.wrap(bytes), manifest)
