Class JCloudsBinaryManager

java.lang.Object

org.nuxeo.ecm.core.blob.binary.AbstractBinaryManager

org.nuxeo.ecm.core.blob.binary.CachingBinaryManager

org.nuxeo.ecm.blob.jclouds.JCloudsBinaryManager

All Implemented Interfaces:

BinaryManager

public class JCloudsBinaryManager
extends CachingBinaryManager

A Binary Manager that stores binaries in cloud blob stores using jclouds.

The BLOBs are cached locally on first access for efficiency.

Because the BLOB length can be accessed independently of the binary stream, it is also cached in a simple text file if accessed before the stream.
