Interface Indexable

public interface Indexable

An interface implemented to let users access data classes via an Indexer. The class implementing this interface can choose the type (byte, short, etc.) of the indexer, and whether it is array-based or direct. The Indexer.release() method should also be overridden to copy back any data written in the case of non-direct indexers.

Method Detail

createIndexer

<I extends Indexer> I createIndexer(boolean direct)

Factory method called by the user to get an indexer to access the data. Eventually, Indexer.release() should be called to have changes reflected in the underlying data.

Type Parameters:

I - the type of the returned object

Parameters:

direct - a hint for the implementation, leaving the choice up to the user, since buffers are slower than arrays on Android, but not with OpenJDK, for example

Returns:

a concrete Indexer

Throws:

NullPointerException - when there is no data
