Member Function Documentation

◆ Present()

static SerializedItemDescriptor launchdarkly::server_side::integrations::SerializedItemDescriptor::Present	(	std::uint64_t const	version,
		std::string	data
	)

inlinestatic

Constructs a SerializedItemDescriptor from a version and a serialized item.

Parameters

version	Version of item.
data	Serialized item.

Returns: SerializedItemDescriptor.

◆ Tombstone()

static SerializedItemDescriptor launchdarkly::server_side::integrations::SerializedItemDescriptor::Tombstone	(	std::uint64_t const	version,
		std::string	tombstone_rep
	)

inlinestatic

Constructs a SerializedItemDescriptor from a version and a tombstone.

This is used when an item is deleted: the tombstone can be stored in place of the item, and the version checked in the future. Without the tombstone, out-of-order data updates could "resurrect" a deleted item.

Parameters

version	Version of the item.
tombstone_rep	Serialized tombstone representation of the item.

Returns: SerializedItemDescriptor.

Member Data Documentation

◆ deleted

bool launchdarkly::server_side::integrations::SerializedItemDescriptor::deleted

During an Init/Upsert, when this is true, the serializedItem will contain a tombstone representation. If the persistence implementation can efficiently store the deletion state, and version, then it may choose to discard the item.
