Patch to Phantom 1.8.x for ByteBuffer handling

gistfile1.scala

// Primitive.scala - only change is asCql method

  implicit object BlobIsPrimitive extends Primitive[ByteBuffer] {

    override type PrimitiveType = java.nio.ByteBuffer

    val cassandraType = CQLSyntax.Types.Blob

    override def fromRow(column: String, row: Row): Try[ByteBuffer] = nullCheck(column, row) {
      r => r.getBytes(column)
    }

    override def asCql(value: ByteBuffer): String = Bytes.toHexString(value)

    override def fromString(value: String): ByteBuffer = Bytes.fromHexString(value)

    override def clz: Class[java.nio.ByteBuffer] = classOf[java.nio.ByteBuffer]
  }


// Addition to PrimitiveTest.scala

  it should "convert ByteBuffers to valid hex bytes" in {
    val buf = ByteBuffer.wrap(Array[Byte](1, 2, 3, 4, 5))
    Primitive[ByteBuffer].asCql(buf) shouldEqual "0x0102030405"

    buf.position(2)   // Non-zero position
    Primitive[ByteBuffer].asCql(buf) shouldEqual "0x030405"

    val slice = buf.slice()   // Slice with non-zero arrayOffset
    Primitive[ByteBuffer].asCql(slice) shouldEqual "0x030405"
  }
