               java.lang.String id)

IndexId

        throws java.io.IOException

Throws:

java.io.IOException

Method Detail

getName

public java.lang.String getName()

The name of the index.

getId

public java.lang.String getId()

The unique ID for the index within the repository. This is *not* the same as the index's UUID, but merely a unique file/URL friendly identifier that a repository can use to name blobs for the index. We could not use the index's actual UUID (See Index.getUUID()) because in the case of snapshot/restore, the index UUID in the snapshotted index will be different from the index UUID assigned to it when it is restored. Hence, the actual index UUID is not useful in the context of snapshot/restore for tying a snapshotted index to the index it was snapshot from, and so we are using a separate UUID here.
