 <div class="block">ArrowBuf serves as a facade over underlying memory by providing
  several access APIs to read/write data into a chunk of direct
  memory. All the accounting, ownership and reference management
  is done by <a href="../../../../org/apache/arrow/memory/ReferenceManager.html" title="interface in org.apache.arrow.memory"><code>ReferenceManager</code></a> and ArrowBuf can work
  with a custom user provided implementation of ReferenceManager
  <p>
  Two important instance variables of an ArrowBuf:
  (1) address - starting virtual address in the underlying memory
  chunk that this ArrowBuf has access to
  (2) length - length (in bytes) in the underlying memory chunk
  that this ArrowBuf has access to
  </p>
  <p>
  The management (allocation, deallocation, reference counting etc) for
  the memory chunk is not done by ArrowBuf.
  Default implementation of ReferenceManager, allocation is in
  <code>BaseAllocator</code>, <a href="../../../../org/apache/arrow/memory/BufferLedger.html" title="class in org.apache.arrow.memory"><code>BufferLedger</code></a> and <a href="../../../../org/apache/arrow/memory/AllocationManager.html" title="class in org.apache.arrow.memory"><code>AllocationManager</code></a>
