com.couchbase.client.java.document.JsonDocument
Represents a {@link Document} that contains a {@link JsonObject} as the content.The {@link JsonDocument} is one of the most integral parts of the API. It is intended to be used as a canonicalwrapper around retrieval and mutation operations, abstracting away JSON internals. Note that there is no public constructor available, but rather a multitude of factory methods that allow you to work nicely with this immutable value object. It is possible to construct empty/fresh ones, but also copies will be created from passed in documents, allowing you to override specific parts during the copy process. This document is interoperable with other SDKs. It can always be the case that some or all fields of a {@link JsonDocument} are not set, depending on the operationperformed. Here are the accessible fields and their default values: +---------+---------+ | Field | Default | +---------+---------+ | id | null | | content | null | | cas | 0 | | expiry | 0 | | status | null | +---------+---------+ @author Michael Nitschinger @since 2.0
