Class S3Storage

java.lang.Object

de.iip_ecosphere.platform.deviceMgt.minio.S3Storage

All Implemented Interfaces:

de.iip_ecosphere.platform.deviceMgt.storage.Storage

Direct Known Subclasses:

S3PackageStorage

public class S3Storage
extends Object
implements de.iip_ecosphere.platform.deviceMgt.storage.Storage

A S3Storage grants access to the storage through s3. For this purpose it uses MinioClient to communicate with the s3 storage. The storage can be set to a fixed prefix, so it is only working with a subset of the bucket.
