Detailed Description

template<typename TReal>
struct zk::basic_version< TReal >

Base type for version types.

These are distinct so we can emit a compilation error on attempts to use the incorrect version type (for example, client::set_acl does a check on acl_version instead of the standard version).

acl_version

Member Function Documentation

template<typename TReal>

static constexpr TReal zk::basic_version< TReal >::any ( )

inlinestatic

When specified in an operation, this version specifier will always pass.

It is the equivalent to not performing a version check.

Definition at line 122 of file types.hpp.

template<typename TReal>

static constexpr TReal zk::basic_version< TReal >::invalid ( )

inlinestatic

An invalid version specifier.

This will never be returned by the database and will always be rejected in commit operations. This is a good value to use as a placeholder when you are searching for the proper version.
