## Public Methods

#### public static ArrayList<T> freezeAndClose (DataBuffer<E> buffer)

Utility helper method to freeze a DataBuffer into a list of concrete entities. The DataBuffer provided here must contain elements that implement the `Freezable` interface.

Note that this will close the buffer, so do not attempt to use it afterwards.

Type T is the type of object returned by freezing an element of the DataBuffer. In most cases, this will be the same as `E`.

Type E is the type of object contained by the DataBuffer. Must implement `Freezable`.

##### Parameters

buffer | `DataBuffer` to freeze contents from.

##### Returns

- ArrayList of objects represented by the buffer.

#### public static boolean hasData (DataBuffer<?> buffer)

Utility function to determine whether a data buffer has data or not.

##### Parameters

buffer | The data buffer to check.

##### Returns

- Whether the data buffer has data or not.

#### public static boolean hasNextPage (DataBuffer<?> buffer)

Utility function to get the "next page" pagination token from a data buffer.

#### public static boolean hasPrevPage (DataBuffer<?> buffer)

Utility function to get the "prev page" pagination token from a data buffer.
