oid	- The OID of the commit to retrieve.

Returns

A maybe<commit_t> containing the commit if found, or an empty maybe if not found.

operator()() [3/3]

maybe< commit_t > oxy::core::get_commit_fn::operator()	(	const connection_ptr &	conn,
		const reference_t &	ref ) const

Parameters

conn	- A pointer to the database (container) connection from which to retrieve the commit.
ref	- The reference representing the commit to retrieve.

Returns

A maybe<commit_t> containing the commit if found, or an empty maybe if not found.
