◆ build()

◆ cas()
Specifies a CAS value that will be taken into account on the server side for optimistic concurrency.
The CAS value is an opaque identifier which is associated with a specific state of the document on the server. The CAS value is received on read operations (or after mutations) and can be used during a subsequent mutation to make sure that the document has not been modified in the meantime.
If document on the server has been modified in the meantime the SDK will raise a errc::common::cas_mismatch
. In this case the caller is expected to re-do the whole "fetch-modify-update" cycle again. Please refer to the SDK documentation for more information on CAS mismatches and subsequent retries.
- Parameters
-
cas | the opaque CAS identifier to use for this operation. |
- Returns
- the
replace_options
for chaining purposes.

◆ expiry() [1/2]
Sets the expiry for the document.
By default the document will never expire.
The duration must be less than 50 years. For expiry further in the future, use expiry(std::chrono::system_clock::time_point)
.
- Parameters
-
duration | the duration after which the document will expire (zero duration means never expire). |
- Returns
- this options class for chaining purposes.

◆ expiry() [2/2]
auto expiry |
( |
std::chrono::system_clock::time_point | time_point | ) |
-> replace_options&
|
|
inline |
Sets the expiry for the document.
By default the document will never expire.
- Parameters
-
time_point | the point in time when the document will expire (epoch second zero means never expire). |
- Returns
- this options class for chaining purposes.
- Since
- 1.0.0
- Committed
- Generally available API and should be preferred in production
◆ preserve_expiry()
Specifies whether an existing document's expiry should be preserved.
Defaults to false.
If true, and the document exists, its expiry will not be modified. Otherwise the document's expiry is determined by expiry(std::chrono::seconds)
or expiry(std::chrono::system_clock::time_point)
.
Requires Couchbase Server 7.0 or later.
- Parameters
-
preserve | true to preserve expiry, false to set new expiry |
- Returns
- this options class for chaining purposes.
