Public methods
freezeAndClose
public static ArrayList<T> <T, E extends Freezable<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 theFreezable 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 asE.
Type E is the type of object contained by the DataBuffer. Must implementFreezable.
| Parameters | |
|---|---|
DataBuffer<E> buffer |
|
| Returns | |
|---|---|
ArrayList<T> | ArrayList of objects represented by the buffer. |
hasData
public static boolean hasData(DataBuffer<Object> buffer)
Utility function to determine whether a data buffer has data or not.
| Parameters | |
|---|---|
DataBuffer<Object> buffer | The data buffer to check. |
| Returns | |
|---|---|
boolean | Whether the data buffer has data or not. |
hasNextPage
public static boolean hasNextPage(DataBuffer<Object> buffer)
Utility function to get the "next page" pagination token from a data buffer.
hasPrevPage
public static boolean hasPrevPage(DataBuffer<Object> buffer)
Utility function to get the "prev page" pagination token from a data buffer.
