Detailed Description

Options for mutate_in().

Since: 1.0.0

Committed: Generally available API and should be preferred in production

Member Function Documentation

◆ access_deleted()

auto access_deleted ( bool value ) -> mutate_in_options &

inline

For internal use only: allows access to deleted documents that are in 'tombstone' form.

Since: 1.0.0

Internal: Internal interface

◆ build()

auto build ( ) const -> built

inlinenodiscard

Validates options and returns them as an immutable value.

Returns: consistent options as an immutable value

Exceptions

std::system_error with code errc::common::invalid_argument if the options are not valid

Since: 1.0.0

Internal: Internal interface

◆ cas()

auto cas ( couchbase::cas cas ) -> mutate_in_options &

inline

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 mutate_in_options for chaining purposes.

Since: 1.0.0

Committed: Generally available API and should be preferred in production

◆ create_as_deleted()

auto create_as_deleted ( bool value ) -> mutate_in_options &

inline

For internal use only: allows creating documents in 'tombstone' form.

Since: 1.0.0

Internal: Internal interface

◆ expiry() [1/2]

auto expiry ( std::chrono::seconds duration ) -> mutate_in_options &

inline

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.

Since: 1.0.0

Committed: Generally available API and should be preferred in production

◆ expiry() [2/2]

auto expiry ( std::chrono::system_clock::time_point time_point ) -> mutate_in_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()

auto preserve_expiry ( bool preserve ) -> mutate_in_options &

inline

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.

Since: 1.0.0

Committed: Generally available API and should be preferred in production

◆ store_semantics()

auto store_semantics ( couchbase::store_semantics semantics ) -> mutate_in_options &

inline

Changes the storing semantics of the outer/enclosing document.

While each individual mutate_in_specs describes the semantics of the respective sub-document section, the store_semantics are applied to the outer enclosing document as a whole. You can think of using the same verb for a store_semantics aligns with the corresponding full document. So for example a store_semantics::insert works semantically similar to a collection#insert() and will fail if the document as a whole already exists.

Parameters

semantics the store semantics to apply to the document.

Returns: this mutate_in_options for chaining purposes.
