A document slice is a document built from a data slice of an existing document. It's completely separate from the original document and has its own store and internalList. The new document's data also contains the entirety of the original document's internal list. It's possible to create a document slice of data located inside the internal list, in which case the resulting document will contain that data twice (one mutable copy at the top level, and one immutable copy in the internal list). ve.dm.Document.js: * Optionally take an internalList in the constructor. This allows us to create a document with a clone of an existing internalList rather than an empty one. * Add edgeMetadata flag to getFullData() ve.dm.IndexValueStore.js, ve.dm.InternalList.js: * Make these classes cloneable Change-Id: I93e06f764ace16aee9df941b07f8c2bff1a28e2b
