Detailed Description

Function object to retrieve data associated with objects in the container.

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

operator()() [1/2]

auto oxy::core::object::get_data_fn::operator()	(	connection_ptr const &	conn,
		oid_t const &	item ) const -> maybe< result_t >

Parameters

conn	- The connection pointer to the container.
item	- The OID of the object to retrieve data for.

Returns

A maybe<contents_t> indicating whether the data was found for the specified OID.

operator()() [2/2]

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

Parameters

conn	- The connection pointer to the container.
items	- A vector of OIDs to retrieve data for.

Returns

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