public class BinaryIntArrayReference
extends AbstractReference
implements ByteableIntArrayValues, BytesMarshallable

Array of 32-bit values laid out as [capacity][used][values...] in little-endian order. Each entry is shifted by SHIFT bytes from VALUES.

Example usage:

 BytesStore bytesStore = ...
 BinaryIntArrayReference arrayRef = new BinaryIntArrayReference();
 arrayRef.bytesStore(bytesStore, 0, bytesStore.capacity());
 arrayRef.setOrderedValueAt(5, 12345);
 int value = arrayRef.getValueAt(5);
 

Note: This class is not thread-safe. External synchronisation may be required if instances are shared between threads.
