## Class Overview

Base class for a buffer of typed data. A `DataBuffer` wraps data provided across the binder from Google Play services.

int | describeContents()
abstract T | get(int position) Get the item at the specified position.
int | getCount()
boolean | isClosed() This method is deprecated. `release()` is idempotent, and so is safe to call multiple times
Iterator<T> | iterator()
void | release() Releases resources used by the buffer.
Iterator<T> | singleRefIterator() In order to use this one should correctly override setDataRow(int) in his DataBufferRef implementation.

## Public Methods

#### public final void close ()

This method is deprecated.
use `release()` instead

#### public int describeContents ()

#### public abstract T get (int position)

Get the item at the specified position. Note that the objects returned from subsequent invocations of this method for the same position may not be identical objects, but will be equal in value. In other words:

`buffer.get(i) == buffer.get(i)` may return false.

`buffer.get(i).equals(buffer.get(i))` will return true.

##### Parameters

position | The position of the item to retrieve.

##### Returns

- the item at `position` in this buffer.

#### public int getCount ()

#### public boolean isClosed ()

This method is deprecated.
`release()` is idempotent, and so is safe to call multiple times

#### public Iterator<T> iterator ()

#### public void release ()

Releases resources used by the buffer. This method is idempotent.

#### public Iterator<T> singleRefIterator ()

In order to use this one should correctly override setDataRow(int) in his DataBufferRef implementation. Be careful: there will be single DataBufferRef while iterating. If you are not sure - DO NOT USE this iterator.
