Detailed Description

Function object to retrieve objects from the container.

This function object provides three operator() overloads: one that takes a connection pointer and returns a coroutine pull type that yields all objects in the container, another that takes a connection pointer and a vector of OIDs and returns a coroutine pull type that yields the corresponding objects, and a third that takes a connection pointer and a single OID and returns a maybe<object_t> indicating whether the object was found. It is designed to be used in a coroutine-based context for efficient retrieval of objects.

operator()() [1/3]

auto oxy::core::object::get_fn::operator()

(

connection_ptr const &

conn

)

const -> coro_t::pull_type

Parameters

conn	- The connection pointer to the container.

Returns

A coroutine pull type that yields all objects in the container.

operator()() [2/3]

auto oxy::core::object::get_fn::operator()	(	connection_ptr const &	conn,
		oid_t const &	oid ) const -> maybe< object_t >

Parameters

conn	- The connection pointer to the container.
oid	- The OID of the object to retrieve.

Returns

A maybe<object_t> indicating whether the object was found.

operator()() [3/3]

auto oxy::core::object::get_fn::operator()	(	connection_ptr const &	conn,
		std::vector< oid_t > const &	oids ) const -> coro_t::pull_type

Parameters

conn	- The connection pointer to the container.
oids	- A vector of OIDs to retrieve objects for.

Returns

A coroutine pull type that yields the corresponding objects for the specified OIDs.
