Examples of ByteArrayRef

org.activiti.engine.impl.persistence.entity.ByteArrayRef
Encapsulates the logic for transparently working with {@link ByteArrayEntity}.

Make sure that instance variables (i.e. fields) of this type are always initialized, and thus never null.

For example:
```
 private final ByteArrayRef byteArrayRef = new ByteArrayRef(); 
```

org.apache.hadoop.hive.serde2.lazy.ByteArrayRef
ByteArrayRef stores a reference to a byte array. The LazyObject hierarchy uses a reference to a single ByteArrayRef, so that it's much faster to switch to the next row and release the reference to the old row (so that the system can do garbage collection if needed).

Examples of org.apache.hadoop.hive.serde2.lazy.ByteArrayRef

        
        // Keys are always primitive
        LazyPrimitive<?, ?> key = LazyFactory.createLazyPrimitiveClass(
            (PrimitiveObjectInspector)
            ((MapObjectInspector) getInspector()).getMapKeyObjectInspector());
        ByteArrayRef keyRef = new ByteArrayRef();
        keyRef.setData(columnKey);
        key.init(
          keyRef, columnFamily.length, columnKey.length - columnFamily.length);
        
        // Value
        LazyObject value = LazyFactory.createLazyObject(
          ((MapObjectInspector) getInspector()).getMapValueObjectInspector());
        ByteArrayRef valueRef = new ByteArrayRef();
        valueRef.setData(columnValue);
        value.init(valueRef, 0, columnValue.length);
        
        // Put it into the map
        cachedMap.put(key.getObject(), value.getObject());
      }
