Member Function Documentation

build()

auto build ( ) const -> built

inline

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 ) -> replace_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 replace_options for chaining purposes.

expiry() [1/2]

auto expiry ( std::chrono::seconds duration ) -> replace_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.

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.

preserve_expiry()

auto preserve_expiry ( bool preserve ) -> replace_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.
