3 9%Egy%@sndZddlZGdddZddZddZd d Zd d Zd dZddZ ddZ ddZ ddZ ddZ dS)a Functions to interact with Arrow memory allocated by Arrow Java. These functions convert the objects holding the metadata, the actual data is not copied at all. This will only work with a JVM running in the same process such as provided through jpype. Modules that talk to a remote JVM like py4j will not work as the memory addresses reported by them are not reachable in the python process.
