- All Implemented Interfaces:
- LazyObject
- Direct Known Subclasses:
- LazyArray, LazyMap, LazyStruct
public abstract class LazyNonPrimitive
- extends Object
- implements LazyObject
LazyPrimitive stores a primitive Object in a LazyObject.

the actual primitive Object. |

init
public void init(ByteArrayRef bytes,
int start,
int length)
- Description copied from interface:
LazyObject
- Set the data for this LazyObject.
We take ByteArrayRef instead of byte[] so that we will be able to drop
the reference to byte[] by a single assignment.
The ByteArrayRef object can be reused across multiple rows.
- Specified by:
init
in interface LazyObject
- Parameters:
bytes
- The wrapper of the byte[].start
- The start position inside the bytes.length
- The length of the data, starting from "start"- See Also:
ByteArrayRef
getObject
public Object getObject()
- Description copied from interface:
LazyObject
- If the LazyObject is a primitive Object, then deserialize it and return
the actual primitive Object.
Otherwise (array, map, struct), return this.
- Specified by:
getObject
in interface LazyObject
