Class LookupInSpec

Direct Known Subclasses:

public abstract class LookupInSpec extends Object
Defines specs to lookup parts in a JSON document.

Operations allow specifying an empty path ("") which means that the root document level is used (so it will be applied to the full document). By nature it makes sense to only use such a command in isolation, but it can be combined with xattr (extended attributes, a document metadata section) operations as well.
