Package org.apache.jackrabbit.oak.upgrade.cli.blob

Class LoopbackBlobStore

  • All Implemented Interfaces:
    java.lang.AutoCloseable, org.apache.jackrabbit.oak.spi.blob.BlobStore
    public class LoopbackBlobStore
extends java.lang.Object
implements org.apache.jackrabbit.oak.spi.blob.BlobStore
    Utility BlobStore implementation to be used in tooling that can work with a FileStore without the need of the DataStore being present locally. Additionally instead of failing it tries to mimic and return blob reference passed in by caller by passing it back as a binary. Example: requesting blobId = e7c22b994c59d9 it will return the e7c22b994c59d9 text as a UTF-8 encoded binary file.
