Method Detail

getObject

public Object getObject()

Description copied from class: LazyObjectBase

If the LazyObjectBase is a primitive Object, then deserialize it and return the actual primitive Object. Otherwise (array, map, struct), return this.

Specified by:

getObject in class LazyObjectBase

init

public void init(ByteArrayRef bytes,
                 int start,
                 int length)

Description copied from class: LazyObjectBase

Set the data for this LazyObjectBase. 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 class LazyObjectBase

Parameters:

bytes - The wrapper of the byte[].

start - The start position inside the bytes.

length - The length of the data, starting from "start"

hashCode
